HIV DNA by PCR

This test can detect the actual virus in a person's bloodstream by using advanced polymerase chain reaction (PCR) technology. PCR allows the amplification and identification of specific DNA sequences from a patient's blood sample. Because PCR can directly detect the presence of a virus in a person's genetic material, it has emerged as the "gold standard" in identifying and managing infectious diseases like HIV/AIDS and hepatitis. This test, in most cases is able to identify HIV infection prior to the evolution of HIV antibodies.

This test was originally designed to identify HIV infection in babies born to HIV positive mothers', and to clarify indeterminate HIV antibody results. Since it takes a person's body a while longer to produce antibodies, many people have opted to take this test in lieu of the standard antibody assay. Researchers have determined that the most effective time to take this test for early detection is approximately 28 days (or later) after suspected infection.

Many people question why this test isn't used routinely, replacing the antibody test. The first consideration is cost. DNA by PCR technology is much more labor intensive than the antibody screen, making it more expensive to the consumer. Time is also a consideration. While the antibody test can render results quite quickly, the DNA test will take longer to yield results. The average turnaround time is 3-4 working days. Finally, this test, while being extremely specific, will not identify all HIV strains (rare subtypes)100% of the time. It is therefore advisable to follow this test with the standard antibody assay at a later date.
