You can now order all kinds of medical tests online. Our research shows this is (mostly) a bad idea

Many of us have done countless rapid antigen tests (RATs) over the course of the pandemic. Testing ourselves at home has become second nature.
But there’s also a growing worldwide market in medical tests sold online directly to the public. These are “direct-to-consumer” tests, and you can access them without seeing a doctor.
While this might sound convenient, the benefits to most consumers are questionable, as we discovered in a recent study.
What are direct-to-consumer tests?
Let’s start with what they’re not. We’re not talking about patients who are diagnosed with a condition, and use tests to monitor themselves (for example, finger-prick testing to monitor blood sugar levels for people with diabetes).
We’re also not talking about home testing kits used for population screening, such as RATs for COVID, or the “poo tests” sent to people aged 50 and over for bowel cancer screening.
Direct-to-consumer tests are products marketed to anyone who is willing to pay, without going through their GP. They can include hormone profiling tests, tests for thyroid disease and food sensitivity tests, among many others.
Some direct-to-consumer tests allow you to complete the test at home, while self-collected lab tests give you the equipment to collect a sample, which you then send to a lab. You can now also buy pathology requests for a lab directly from a company without seeing a doctor.

What we did in our study
We searched (via Google) for direct-to-consumer products advertised for sale online in Australia between June and December 2021. We then assessed whether each test was likely to provide benefits to those who use them based on scientific literature published about the tests, and any recommendations either for or against their use from professional medical organisations.
We identified 103 types of tests and 484 individual products ranging in price from A$12.99 to A$1,947.
We concluded only 11% of these tests were likely to benefit most consumers. These included tests for STIs, where social stigma can sometimes discourage people from testing at a clinic.
A further 31% could possibly benefit a person, if they were at higher risk. For example, if a person had symptoms of thyroid disease, a test may benefit them. But the Royal Australian College of General Practitioners does not recommend testing for thyroid disease in people without symptoms because evidence showing benefits of identifying and treating people with early thyroid disease is lacking.
Some 42% were commercial “health checks” such as hormone and nutritional status tests. Although these are legitimate tests – they may be ordered by a doctor in certain circumstances, or be used in research – they have limited usefulness for consumers.
A test of your hormone or vitamin levels at a particular time can’t do much to help you improve your health, especially because test results change depending on the time of day, month or season you test.
Most worryingly, 17% of the tests were outright “quackery” that wouldn’t be recommended by any mainstream health practitioner. For example, hair analysis for assessing food allergies is unproven and can lead to misdiagnosis and ineffective treatments.
More than half of the tests we looked at didn’t state they offered a pre- or post-test consultation.

Products available may change outside the time frame of our study, and direct-to-consumer tests not promoted or directly purchasable online, such as those offered in pharmacies or by commercial health clinics, were not included.
But in Australia, ours is the first and only study we know of mapping the scale and variety of direct-to-consumer tests sold online.
Research from other countries has similarly found a lack of evidence to support the majority of direct-to-consumer tests.
4 questions to ask before you buy a test online
Many direct-to-consumer tests offer limited benefits, and could even lead to harms. Here are four questions you should ask yourself if you’re considering buying a medical test online.
1. If I do this test, could I end up with extra medical appointments or treatments I don’t need?
Doing a test yourself might seem harmless (it’s just information, after all), but unnecessary tests often find issues that would never have caused you problems.
For example, someone taking a diabetes test may find moderately high blood sugar levels see them labelled as “pre-diabetic”. However, this diagnosis has been controversial, regarded by many as making patients out of healthy people, a large number of whom won’t go on to develop diabetes.
2. Would my GP recommend this test?
If you have worrying symptoms or risk factors, your GP can recommend the best tests for you. Tests your GP orders are more likely to be covered by Medicare, so will cost you a lot less than a direct-to-consumer test.
3. Is this a good quality test?
A good quality home self-testing kit should indicate high sensitivity (the proportion of true cases that will be accurately detected) and high specificity (the proportion of people who don’t have the disease who will be accurately ruled out). These figures should ideally be in the high 90s, and clearly printed on the product packaging.
For tests analysed in a lab, check if the lab is accredited by the National Association of Testing Authorities. Avoid tests sent to overseas labs, where Australian regulators can’t control the quality, or the protection of your sample or personal health information.
4. Do I really need this test?
There are lots of reasons to want information from a test, like peace of mind, or just curiosity. But unless you have clear symptoms and risk factors, you’re probably testing yourself unnecessarily and wasting your money.
Direct-to-consumer tests might seem like a good idea, but in most cases, you’d be better off letting sleeping dogs lie if you feel well, or going to your GP if you have concerns.

Psychedelics and Psychotherapy – Edited by Dr. Tim Read & Maria Papaspyrou
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
A quick note on authorship, first: this book is edited by the psychiatrist and psychotherapist credited above, but after the introductory section, the rest of the chapters are written by experts on the individual topics.As such, the style will vary somewhat, from chapter to chapter.
What this book isn’t: “try drugs and feel better!”
Rather, the book explores the various ways in which assorted drugs can help people to—even if just briefly—shed things they didn’t know they were carrying, or otherwise couldn’t put down, and access parts of themselves they otherwise couldn’t.
We also get to read a lot about the different roles the facilitator can play in guiding the therapeutic process, and what can be expected out of each kind of experience. This varies a lot from one drug to another, so it makes for very worthwhile reading, if that’s something you might consider pursuing. Knowledge makes for much more informed choices!
Bottom line: if you’re curious about the therapeutic potential of psychedelics, and want a reference that’s more personal than dry clinical studies, but still more “safe and removed” than diving in by yourself, this is the book for you.

Alzheimer’s: The Bad News And The Good

Dr. Devi’s Spectrum of Hope
This is Dr. Gayatri Devi. She’s a neurologist, board-certified in neurology, pain medicine, psychiatry, brain injury medicine, and behavioral neurology.
She’s also a Clinical Professor of Neurology, and Director of Long Island Alzheimer’s Disease Center, Fellow of the American Academy of Neurology, and we could continue all day with her qualifications, awards and achievements but then we’d run out of space. Suffice it to say, she knows her stuff.
Especially when it comes to the optimal treatment of stroke, cognitive loss, and pain.
In her own words:
❝Helping folks live their best lives—by diagnosing and managing complex neurologic disorders—that’s my job. Few things are more fulfilling! For nearly thirty years, my focus has been on brain health, concussions, Alzheimer’s and other dementias, menopause related memory loss, and pain.❞
Alzheimer’s is more common than you might think
According to Dr. Devi,
❝97% of patients with mild Alzheimer’s disease don’t even get diagnosed in their internist offices, and half of patients with moderate Alzheimer’s don’t get diagnosed.
What that means is that the percentage of people that we think about when we think about Alzheimer’s—the people in the nursing home—that’s a very, very small fraction of the entirety of the people who have the condition❞
As for what she would consider the real figures, she puts it nearer 1 in 10 adults aged 65 and older.
Source: Neurologist dispels myths about Alzheimer’s disease
Her most critical advice? Reallocate your worry.
A lot of people understandably worry about a genetic predisposition to Alzheimer’s, especially if an older relative died that way.
See also: Alzheimer’s, Genes, & You
However, Dr. Devi points out that under 5% of Alzheimer’s cases are from genetics, and the majority of Alzheimer’s cases can be prevented be lifestyle interventions.

Lastly, she wants us to skip the stigma
Outside of her clinical practice and academic work, this is one of the biggest things she works on, reducing the stigma attached to Alzheimer’s both publicly and professionally:

Federal Panel Prescribes New Mental Health Strategy To Curb Maternal Deaths
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
BRIDGEPORT, Conn. — Milagros Aquino was trying to find a new place to live and had been struggling to get used to new foods after she moved to Bridgeport from Peru with her husband and young son in 2023.
When Aquino, now 31, got pregnant in May 2023, “instantly everything got so much worse than before,” she said. “I was so sad and lying in bed all day. I was really lost and just surviving.”
Aquino has lots of company.
Perinatal depression affects as many as 20% of women in the United States during pregnancy, the postpartum period, or both, according to studies. In some states, anxiety or depression afflicts nearly a quarter of new mothers or pregnant women.
Many women in the U.S. go untreated because there is no widely deployed system to screen for mental illness in mothers, despite widespread recommendations to do so. Experts say the lack of screening has driven higher rates of mental illness, suicide, and drug overdoses that are now the leading causes of death in the first year after a woman gives birth.
“This is a systemic issue, a medical issue, and a human rights issue,” said Lindsay R. Standeven, a perinatal psychiatrist and the clinical and education director of the Johns Hopkins Reproductive Mental Health Center.
Standeven said the root causes of the problem include racial and socioeconomic disparities in maternal care and a lack of support systems for new mothers. She also pointed a finger at a shortage of mental health professionals, insufficient maternal mental health training for providers, and insufficient reimbursement for mental health services. Finally, Standeven said, the problem is exacerbated by the absence of national maternity leave policies, and the access to weapons.
Those factors helped drive a 105% increase in postpartum depression from 2010 to 2021, according to the American Journal of Obstetrics & Gynecology.
For Aquino, it wasn’t until the last weeks of her pregnancy, when she signed up for acupuncture to relieve her stress, that a social worker helped her get care through the Emme Coalition, which connects girls and women with financial help, mental health counseling services, and other resources.
Mothers diagnosed with perinatal depression or anxiety during or after pregnancy are at about three times the risk of suicidal behavior and six times the risk of suicide compared with mothers without a mood disorder, according to recent U.S. and international studies in JAMA Network Open and The BMJ.
The toll of the maternal mental health crisis is particularly acute in rural communities that have become maternity care deserts, as small hospitals close their labor and delivery units because of plummeting birth rates, or because of financial or staffing issues.
This week, the Maternal Mental Health Task Force — co-led by the Office on Women’s Health and the Substance Abuse and Mental Health Services Administration and formed in September to respond to the problem — recommended creating maternity care centers that could serve as hubs of integrated care and birthing facilities by building upon the services and personnel already in communities.
The task force will soon determine what portions of the plan will require congressional action and funding to implement and what will be “low-hanging fruit,” said Joy Burkhard, a member of the task force and the executive director of the nonprofit Policy Center for Maternal Mental Health.
Burkhard said equitable access to care is essential. The task force recommended that federal officials identify areas where maternity centers should be placed based on data identifying the underserved. “Rural America,” she said, “is first and foremost.”
There are shortages of care in “unlikely areas,” including Los Angeles County, where some maternity wards have recently closed, said Burkhard. Urban areas that are underserved would also be eligible to get the new centers.
“All that mothers are asking for is maternity care that makes sense. Right now, none of that exists,” she said.
Several pilot programs are designed to help struggling mothers by training and equipping midwives and doulas, people who provide guidance and support to the mothers of newborns.
In Montana, rates of maternal depression before, during, and after pregnancy are higher than the national average. From 2017 to 2020, approximately 15% of mothers experienced postpartum depression and 27% experienced perinatal depression, according to the Montana Pregnancy Risk Assessment Monitoring System. The state had the sixth-highest maternal mortality rate in the country in 2019, when it received a federal grant to begin training doulas.
To date, the program has trained 108 doulas, many of whom are Native American. Native Americans make up 6.6% of Montana’s population. Indigenous people, particularly those in rural areas, have twice the national rate of severe maternal morbidity and mortality compared with white women, according to a study in Obstetrics and Gynecology.
Stephanie Fitch, grant manager at Montana Obstetrics & Maternal Support at Billings Clinic, said training doulas “has the potential to counter systemic barriers that disproportionately impact our tribal communities and improve overall community health.”
Twelve states and Washington, D.C., have Medicaid coverage for doula care, according to the National Health Law Program. They are California, Florida, Maryland, Massachusetts, Michigan, Minnesota, Nevada, New Jersey, Oklahoma, Oregon, Rhode Island, and Virginia. Medicaid pays for about 41% of births in the U.S., according to the Centers for Disease Control and Prevention.
Jacqueline Carrizo, a doula assigned to Aquino through the Emme Coalition, played an important role in Aquino’s recovery. Aquino said she couldn’t have imagined going through such a “dark time alone.” With Carrizo’s support, “I could make it,” she said.
Genetic and environmental factors, or a past mental health disorder, can increase the risk of depression or anxiety during pregnancy. But mood disorders can happen to anyone.
Teresa Martinez, 30, of Price, Utah, had struggled with anxiety and infertility for years before she conceived her first child. The joy and relief of giving birth to her son in 2012 were short-lived.
Without warning, “a dark cloud came over me,” she said.
Martinez was afraid to tell her husband. “As a woman, you feel so much pressure and you don’t want that stigma of not being a good mom,” she said.
In recent years, programs around the country have started to help doctors recognize mothers’ mood disorders and learn how to help them before any harm is done.
One of the most successful is the Massachusetts Child Psychiatry Access Program for Moms, which began a decade ago and has since spread to 29 states. The program, supported by federal and state funding, provides tools and training for physicians and other providers to screen and identify disorders, triage patients, and offer treatment options.
But the expansion of maternal mental health programs is taking place amid sparse resources in much of rural America. Many programs across the country have run out of money.
The federal task force proposed that Congress fund and create consultation programs similar to the one in Massachusetts, but not to replace the ones already in place, said Burkhard.
In April, Missouri became the latest state to adopt the Massachusetts model. Women on Medicaid in Missouri are 10 times as likely to die within one year of pregnancy as those with private insurance. From 2018 through 2020, an average of 70 Missouri women died each year while pregnant or within one year of giving birth, according to state government statistics.
Wendy Ell, executive director of the Maternal Health Access Project in Missouri, called her service a “lifesaving resource” that is free and easy to access for any health care provider in the state who sees patients in the perinatal period.
About 50 health care providers have signed up for Ell’s program since it began. Within 30 minutes of a request, the providers can consult over the phone with one of three perinatal psychiatrists. But while the doctors can get help from the psychiatrists, mental health resources for patients are not as readily available.
The task force called for federal funding to train more mental health providers and place them in high-need areas like Missouri. The task force also recommended training and certifying a more diverse workforce of community mental health workers, patient navigators, doulas, and peer support specialists in areas where they are most needed.
A new voluntary curriculum in reproductive psychiatry is designed to help psychiatry residents, fellows, and mental health practitioners who may have little or no training or education about the management of psychiatric illness in the perinatal period. A small study found that the curriculum significantly improved psychiatrists’ ability to treat perinatal women with mental illness, said Standeven, who contributed to the training program and is one of the study’s authors.
Nancy Byatt, a perinatal psychiatrist at the University of Massachusetts Chan School of Medicine who led the launch of the Massachusetts Child Psychiatry Access Program for Moms in 2014, said there is still a lot of work to do.
“I think that the most important thing is that we have made a lot of progress and, in that sense, I am kind of hopeful,” Byatt said.

Learning to Love Midlife – by Chip Conley
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
While the book is titled about midlife, it could have said: midlife and beyond.
Some of the benefits discussed in this book really only kick in during one’s 50s, 60s, or 70s, usually. Which, for all but the most optimistic, is generally considered to be stretching beyond what is usually called “midlife”.
However! Chip Conley makes the argument for midlife being anywhere from one’s early 30s to mid-70s, depending on what (and how) we’re doing in life.
He talks about (as the subtitle promises) 12 reasons life gets better with age, and those reasons are grouped into 5 categories, thus:
- Physical life
- Emotional life
- Mental life
- Vocational life
- Spiritual life
It may surprise some readers that there are physical benefits that come with aging, but we do get two chapters in that category.
The writing style is very casual, yet with references to science throughout, and a bibliography for such.
Bottom line: if you’d like to make sure you’re making the most of your midlife and beyond, this a book that offers a lot of guidance on doing so!

Taurine’s Benefits For Heart Health And More
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Taurine: Research Review
First, what is taurine, beyond being an ingredient in many energy drinks?
It’s an amino acid that many animals, including humans, can synthesize in our bodies. Some other animals—including obligate carnivores such as cats (but not dogs, who are omnivorous by nature) cannot synthesize taurine and must get it from food.
So, as humans are very versatile omnivorous frugivores by nature, we have choices:
- Synthesize it—no need for any conscious action; it’ll just happen
- Eat it—by eating meat, which contains taurine
- Supplement it—by taking supplements, including energy drinks, which generally (but not always) use a bioidentical lab-made taurine. Basically, lab-made taurine is chemically identical to the kind found in meat, it’s just cheaper and doesn’t involve animals as a middleman.
What does it do?
Taurine does a bunch of essential things, including:
- Maintaining hydration/electrolyte balance in cells
- Regulating calcium/magnesium balance in cells
- Forming bile salts, which are needed for digestion
- Supporting the integrity of the central nervous system
- Regulating the immune system and antioxidative processes
Thus, a shortage of taurine can lead to such issues as kidney problems, eye tissue damage (since the eyes are a particularly delicate part of the CNS), and cardiomyopathy.
If you want to read more, here’s an academic literature review:
Taurine: A “very essential” amino acid
On the topic of eye health, a 2014 study found that taurine is the most plentiful amino acid in the eye, and helps protect against retinal degeneration, in which they say:
❝We here review the evidence for a role of taurine in retinal ganglion cell survival and studies suggesting that this compound may be involved in the pathophysiology of glaucoma or diabetic retinopathy. Along with other antioxidant molecules, taurine should therefore be seriously reconsidered as a potential treatment for such retinal diseases❞

Taurine for muscles… In more than sports!
We’d be remiss not to mention that taurine is enjoyed by athletes to enhance athletic performance; indeed, it’s one of its main selling-points:
See: Taurine in sports and exercise
But! It’s also useful for simply maintaining skeleto-muscular health in general, and especially in the context of age-related decline and chronic disease:
Taurine: the appeal of a safe amino acid for skeletal muscle disorders
On the topic of safety… How safe is it?
There’s an interesting answer to that question. Within safe dose ranges (we’ll get to that), taurine is not only relatively safe, but also, studies that looked to explore its risks found new benefits in the process. Specifically of interest to us were that it appears to promote better long-term memory, especially as we get older (as taurine levels in the brain decline with age):
Taurine, Caffeine, and Energy Drinks: Reviewing the Risks to the Adolescent Brain
^Notwithstanding the title, we assure you, the research got there; they said:
❝Interestingly, the levels of taurine in the brain decreased significantly with age, which led to numerous studies investigating the potential neuroprotective effects of supplemental taurine in several different experimental models❞
What experimental models were those? These ones:
- Taurine protects cerebellar neurons of the external granular layer
- Effects of taurine on alterations of neurobehavior and neurodevelopment key proteins expression
- Neuroprotective role of taurine in developing offspring affected by maternal alcohol consumption
…which were all animal studies, however.
The same systematic review also noted that not only was more research needed on humans, but also, existing studies have had a strong bias to male physiology (in both human and assorted other animal studies), so more diverse study is needed too.
What are the safe dose ranges?
Before we get to toxicity, let’s look at some therapeutic doses. In particular, some studies that found that 500mg 3x daily, i.e. 1.5g total daily, had benefits for heart health:
- Taurine and atherosclerosis
- The Anti-Inflammatory Effect of Taurine on Cardiovascular Disease
- Taurine supplementation has anti-atherogenic and anti-inflammatory effects before and after incremental exercise in heart failure
- Taurine Supplementation Lowers Blood Pressure and Improves Vascular Function in Prehypertension
- Taurine improves the vascular tone through the inhibition of TRPC3 function in the vasculature
Bottom line on safety: 3g/day has been found to be safe:
