DNA vs RNA PCR tests
Jan 11, 2009

Dear Dr Howarth What is the difference between the two in terms of accuracy and when to test (accepting that anti-body testing is best form of diagnosis).

Thanks in advance HT

Response from Dr. Horwath

The HIV antibody tests are the most effective screening tools for detecting HIV infection. The DNA and RNA PCR tests are primarily used to monitor disease progression and to assist in making treatment decisions. They use different methodologies but have comparable levels of accuracy in measuring viral load.
