HIV Diagnosed In 15 Minutes




Columbia University men of science have developed a $1 plastic chip that can diagnose HIV and syphilis in 15 minutes. The chip named the "mChip", a credit-card-sized piece of plastic that is made applying a plastic injection molding process, examinations for multiple diseases with just one pinprick of blood. Nothing moves inside the chip, and the microfluidics-based chip can be examined with assist from a cheap visual sensor.




Concording to results issued this week in Nature Medicine, the chip detects 100% of cases when utilized to test HIV or syphilis and human immunodeficiency virus together, with a 4% to 6% false positive rate. That's same to what is ascertained with common laboratory exams in the developed world.


An mChip that can diagnose prostatic adenocarcinoma has already been authorized for use in Europe. In the future, Columbia investigator Samuel K. Sia trusts to practice the chip to examine pregnant women in Rwanda for HIV and other STDs. Numerous of these women domiciliate too far away from laboratories to be diagnosed with conventional techniques. "When you’re in these villages, you may have the drugs for many STDs, but you don’t know who to give treatments to, so the challenge really comes down to diagnostics," Sia explained in a statement.
