A new blood test has been developed that reads your entire virus history by analysing the antibodies in your bloodstream
A revolutionary new blood test will allow doctors to discover every virus that has ever infected a patient – and determine what will affect them in the future.
Called VirScan it was developed by researchers at Harvard Medical School who insist that once it’s refined it will be cheap enough to mass produce. They estimate it will cost a mere £16 for the average person to take.
It works by analysing blood for antibodies for over 1,000 different strains of 206 human viruses simultaneously.
Because antibodies produced by the immune system to fight viruses stay in the blood stream for many years, the test can produce an accurate history of infections.
Up until now, most tests have revolved around looking for just a single virus. But the brains behind VirScan say it can process 100 samples in two to three days.
“We’ve developed a screening methodology to basically look back in time in people’s [blood] sera and see what they have experienced,” said Dr Stephen Elledge from Harvard Medical School, who led the development team.
“Instead of testing for one individual virus at a time, which is labour intensive, we can assay all these at once. It’s one-stop shopping,” he said.
