Genetic testing companies are offering tests that analyze the ends of your chromosomes – telomeres – to gauge your health and your real age. But is there scientific evidence to support such tests?
If you’ve got the raw data, why not mine it for more info?
New research investigated who uses the wide array of tools available to people who've received their own raw genetic data and want to maximize what they learn from it.
A woman uses a lancet on her finger to check her blood sugar level with a glucose meter.
Direct-to-consumer genetic testing company 23andMe is now offering a new 'polygenic risk score' that reveals your risk of developing Type 2 diabetes. Does it work? Are our family physicians ready?
When you share your genetic data – even with the NHS – you don't know where it will end up, or how it will be used.
Researchers find 351 genetic variants associated with a person's chronotype. Before this study, we knew of only 24.
Genetic testing is available to people who want to know if they carry a variant of a gene that confers susceptibility for Alzheimer’s. But knowing whether to get tested is hard.
Alzheimer's is not only the third leading cause of death in the U.S. but also the most dreaded diagnosis. Genetic testing can help determine susceptibility, but knowing whether to test isn't easy.
Users may want to know more than what’s in a basic report from a genetic testing company.
Data and privacy issues are tangled up in the DNA reports consumers get from big genetic testing companies – and the third-party sites they turn to in order to glean more from their raw DNA.
It all begins with spitting in a tube like this one.

More people are sending off saliva samples to find out about their genetic roots. But the raw DNA results go way beyond genealogical data – and could deliver unintended consequences.
Genetic testing for breast cancer gene mutations is now available. But it could lead to over treatment.
A genetics testing company recently won approval from the FDA to market a test that can identify a breast cancer gene mutation. But what are women supposed to do with that information? There's risk involved.
DNA peddling needs to be banned.
The market for personal genome services is facing a reality check. While the most prominent and innovative company 23andMe has flourished so far, in the past few years many of its competitors have gone…
Welcome to nowhere, says FDA.
Genetic testing is a powerful tool. Two years ago, with the help of my colleagues, it was this tool that helped us identify a new disease. The disease, called Ogden Syndrome, caused the death of a four-month…
