PCR and Viral Load Tests?
Qualitative PCR Test - Do I still have the virus?
If an antibody
test is positive, the next test is to check if the virus
is still in your body using a 'qualitative' PCR (polymerase chain
reaction) test. The PCR test determines whether you are currently
infected by detecting active hepatitis C virus replication in the
blood.
A positive PCR test means the virus has been detected in your
body so your immune system was not able to get rid
of the virus by itself during the acute stage. You now have a chronic Hepatitis C
infection.
Viral load/Quantitative PCR test - How much virus ?
A quantitative PCR test (also called a Viral Load Test) is used
to measure the amount of virus in your blood. This is undertaken at
the beginning of treatment to find out how much virus you have in
your body.
The number of viruses in a tiny measurement of your blood is
counted and recorded.
This Viral Load test is then repeated at intervals throughout
your treatment,
so doctors can check how well you are responding.
