The company behind a controversial genetic test that claims to reveal your risk of cancer or Alzheimer's has defended its decision to launch in the UK, despite its health screenings being banned in the US.
Google-backed 23andMe claims the test results could be relied upon to make lifestyle and health changes - most without consulting a doctor. For £125, the test screens your genes using a saliva sample taken at home.
The test is on sale in the UK from today and 10,000 people in this country have already taken it by ordering it from abroad.
It carries out over 100 different tests on health and genetic traits and claims to predict how likely you are to develop conditions including breast cancer, Parkinson's disease and Anaemia.
The home-administered test also claims to uncover genetic traits such as why people are more prone to smoking, how people metabolise coffee, if they are predisposed to long-distance running and details of their genetic ancestry.
But the Department of Health today warned against relying on the data offered by 23andMe, saying people should "think carefully before using private genomic services as no test is 100% reliable."
The US Food and Drug Authority (FDA) went a step further, banning 23andMe's tests in 2013 because the company failed to provide credible evidence to back its advertising claims.
But according to 23andMe, the new tests are "quite different" from the banned US screenings.
“There have been a number of changes to the health reports that we are offering," she said. "We’ve done a lot of work on them in conversation with the medical community,” Angela Calman-Wonson, the company's vice president of communications, told The Huffington Post UK.
"A lot of it has to do with the fact that we are offering information on things like carrier status [for diseases] and information on how you respond to medication - things which have critical validity and that are well-understood in the medical and scientific community, but have a lot of controversy and debate around them."
Calman-Wonson said that people could use the results of the test to make changes to their lives without speaking to a doctor.
“Many of the tests do not requite seeing a physician to make changes to your lifestyle, except in a few cases. For example, if the test gives you information about how you metabolise a drug, we would not recommend for someone to change their medication without talking to a physician."
She denied that the tests would cause people to seek unnecessary medical treatment, placing additional stress on the NHS. 23andMe claims only 4% of those who have used the test in the UK so far have booked an extra GP appointment as a result.
"Many people talk to their families [after taking the test], or make lifestyle changes, rather than going to the GP."
She added: "It's meant to help inform your choices. It’s a screening test, not a diagnostic. So if you were sick, you wouldn’t take this test to find out what was wrong with you, you’d go to your doctor.”
She said the company, in which Google owns a stake, has now submitted more information to the FDA to try to get the tests approved in the US.
“The FDA determined that we needed to go through the process of being cleared as a medical device, which is above and beyond what other genentic testing companies do. We have our first submission with them, with the data to show the validity of the process.”
The UK tests are CE marked, meaning they have been approved by the European Commission.
23andMe - named after the 23 pairs of chromosomes in human DNA - has already "genified" 800,000 people worldwide.
