Inexpensive Blood Test Reveals Your Viral Exposure History?

A international team of scientists has just developed a comprehensive screening mechanism called VirScan. This technology is a high-throughput method that comprehensively analyzes antiviral antibodies using immunoprecipittion and parallel DNA sequencing of a bacteriophage library that displays proteome-wide peptides from all known human viruses. While it might not be a complete history, VirScan revealed the presence of antibodies to 10 or more different viral species per person in a 569-person study that included subjects from the United States, Peru, Thailand, and South Africa. At least two of the individuals tested had at least antibodies against 84 different viral species. The study found 206 different viral species in total, and over 1000 strains.
            Widespread adoption of VirScan could be a great diagnostic and research tool. Current serological testing is usually focused on testing for one pathogen at a time. The analysis costs about $25 per person and only 1 microliter of blood. One of the unexpected results of VirScan was that different people produced structurally similar antibodies to a small number of “public” epitopes for many different viral species. The team hopes that VirScan can be used to study the effect of host-virome interactions on human health, and possibly be expanded for test for bacterial, fungal, and protozoan pathogens.
            Clinically, VirScan could be used to identify antibodies for a virus that a patient might not be aware he/she was exposed to, especially latent viruses that can lead to cancer (e.g. hepatitis C). VirScan could also be used to draw associations between viruses and chronic conditions such as diabetes and chronic fatigue syndrome.

An amazing testimony on a spell caster who brought my wife back to me, My name is Eric Gomez, i lives in Los Angeles CA. and I'm happily married to a lovely and caring wife,with two kids, A very big problem occurred in my family seven months ago,between me and my wife so terrible that she took the case to court for a divorce she said that she never wanted to stay with me again,and that she did not love me anymore So she packed out of my house and made me and my children passed through severe pain. I tried all my possible means to get her back,after much begging,but all to no avail and she confirmed it that she has made her decision,and she never wanted to see me again. So on one evening,as i was coming back from work,i met an old friend of mine who asked of my wife So i explained every thing to her,so she told me that the only way i can get my wife back,is to visit a spell caster,because it has really worked for her too So i never believed in spell,but i had no other choice,than to follow her advice. Then she gave me the email address of the spell caster whom she visited.(}, So the next morning,i sent a mail to the address she gave to me,and the spell caster assured me that i will get my wife back the next day what an amazing statement!! I never believed,so he spoke with me,and told me everything that i need to do. Then the next morning, So surprisingly, my wife who did not call me for the past seven {7}months,gave me a call to inform me that she was coming back So Amazing!! So that was how she came back that same day,with lots of love and joy,and she apologized for her mistake,and for the pain she caused me and my children. Then from that day,our relationship was now stronger than how it were before,by the help of a spell caster . So,you can visit his Web site to know more about him: if you have any problem contact Dr Frank Ojo, i give you 100% guarantee that he will help you. So thanks to Dr Frank Ojo for bringing back my wife,and brought great joy to my family once again.{}, Thanks..
