As humans, we are exposed to a lot of disease causing organisms daily, and at such we contact some virus which we are not even aware of.Now Scientists have developed a new blood test which requires only a drop of your blood to tell you ‘nearly’ every virus you’ve been exposed to in your life time.The test called VirScan (from virus scan) has been conducted on over 570 people in the U.S., Thailand, Peru and South Africa and it was discovered that on average, the participants had been exposed to about 10 different types of virus.The usual methods employed by medical doctors is ‘testing for one virus at a time’. For instance, you’re sick and the symptoms you’re showing are related to, say, Malaria, Fever or Cancer, if the doctor is not sure, he would have to conduct a blood test for each cases. But with this new test (which is still undergoing experiments), it would be easy for the doctor to know your ‘medical history’ at once.VirScan, which costs $25 to perform, can also determine a person’s immunity level to a particular virus and so the doctor would know if one needs more vaccine to guard against that virus.This new test can be seen as a time-saver, a money-saver and also a blood saver (for God knows how I detest the sight of a syringe).So what do you think about virScan? would you love to know all your medical secrets (lol) at once? let us know using the comment box below.
