LONDON (Reuters) - Online health information and disease-risk tests can mislead, confuse and create needless anxiety, and governments should do more ensure the people who use them know what they are buying, UK experts said on Tuesday.

A report by a British medical ethics group said private DNA tests may be "medically or therapeutically meaningless" and could give false results or information that is "unclear, unreliable or inaccurate."

The Nuffield Council on Bioethics called on the government to set up an accreditation scheme for providers of online health records, and for DNA testing and body scanning services to be better regulated to help protect consumers.

"The internet is now often the first port of call for people to find out more about their health. People need to know where they can get accurate health information, how to buy medicines online safely and how any personal information about their health posted online might be used," said Christopher Hood, one of the leading authors of the report.

The report also looked at direct-to-consumer personal genetic tests that say they can predict the risk of a person developing certain diseases in the future.

These tests, and body scanning services involving computed tomography (CT) or magnetic resonance imaging (MRI) scans, are often promoted online as health check-ups, the experts said.

"The reliability of these tests is questionable," Nikolas Rose, another of the report's authors, told reporters at a briefing. "And even if the tests were reliable, the increases in risk over that in the general population that are given to you by these tests are usually minimal, and in almost all circumstances they have no clinical relevance."

Online genetic tests are often marketed to health people online as a way for them to find out their risks of developing serious conditions such as diabetes, heart diseases, Parkinson's or cancer. Those who buy them are asked to provide a DNA sample, usually saliva, which is then analyzed.   Continued...
