PCR
This is a PCR test that looks for tiny amounts of the virus’s RNA (This is the genetic instructions that the virus uses to make copies of itself). You will only have the virus RNA in your blood if you currently have the virus. This is a very specific and confirmatory test as two viruses cannot have the same genetic make up. This test covers Hepatitis A RNA, Hepatitis B DNA, Hepatitis C RNA, HIV-1 and HIV-2 RNA amongst others.
