There are actually 5 different kinds of Hepatitis C test procedures. Each of these tests serves different purposes.
Anti-HCV Tests
These tests primary detect the presence of virus in the body by testing for antibodies. The presence of antibodies indicates that the patient being tested has been exposed to HCV. Unfortunately, these tests do not really indicate whether or not the infection is active or not. This only indicates whether or not you have exposed to hepatitis C virus in the past. Although the test often states whether the patient is “positive” or “negative”, there are instances when the test comes back “weakly positive”. Such result does not conclusively indicate exposure to the virus. It is advised that a patient be tested once again for HCV before a final conclusion is reached.
HCV RIBA Test
This is a hepatitis C test which helps confirm other tests. This determines the presence of antibodies. This test helps determine the validity of an anti-HCV test. It helps determine whether the positive anti-HCV test result was due to actual exposure to the virus or whether the negative result indicates false signal. There are some cases, however, when this test give out an indeterminate result. Like the previous procedure mentioned above, this hepatitis C test fails to determine whether you are currently infected or whether you have only been exposed to the virus.
HCV RNA Test
This type of test helps determine the presence of the virus in your blood. This indicates whether or not you have active HCV infection as well. This test is also requested when there is a need to determine the existence or elimination of the virus from the body after treatment.
Viral Load or Quantitative HCV Tests
This hepatitis C test helps measure the volume of viral RNA particles in the patient’s blood. This is often recommended before and during treatment in order to determine how the patient is faring and responding. Usually, the second test is taken three months after the first one.
Viral Genotyping
This hepatitis C test helps determine the kind of virus one is infected with. There are actually 6 kinds of HCV, the common of which is the genotype 1. Unfortunately, this virus is also less likely to respond to treatment compared to other genotypes specifically the 2 and 3. Genotyping helps determine the kind of treatment that is required. There are viruses that will require longer therapy and treatment while other viruses usually respond fatter than others.
