RNA testing is a cutting edge technology which is used to detect ribonucleic acid from the Hepatitis C virus (also called HCV). There are many different types of RNA technologies, among them the most frequently and predominantly used version is the Polymerase Chain Reaction (PCR) test. PCR viral load testing estimates the amount of hep C virus circulating in your blood. It is performed to confirm Hepatitis C and also during the treatment and after the treatment of Hepatitis C. The test can also measure the exact titer in your blood. The quantitative HCV RNA test is performed on a patient who is currently on diagnosis. The lab report will provide a definitive conclusion regarding the existence of Hepatitis C virus in your body, a numerical result to be specific.
