Frequently Asked Questions

What does PCR testing stand for?

PCR stands for Polymerase Chain Reaction and is a common way of testing for a variety of different organisms. The overall process of extracting and amplifying the genetic material of an organism (in this case HIV) and then testing for it with a PCR test is called Nucleic-acid Amplification Testing or NAT.

How accurate are PCR tests?

A PCR test (viral load test) are neither approved or recommended for routine HIV testing by people who just want to test more quickly than the four weeks recommended with an antigen/antibody test. They are less accurate (actual infections can easily be missed), more expensive and require more complicated laboratory technology.

What does a PCR test look for?

For example, PCR tests can detect and identify pathogenic organisms in patients, especially those that are difficult to cultivate (for example, HIV and other viruses and certain fungi).

What is a PCR test used to identify?

PCR tests are also used to identify and characterize genetic mutations and rearrangements found in certain cancers. However, PCR tests have been modified and extended into many aspects of scientific investigations including evolutionary biology, genetic fingerprinting, forensic investigations, and many others.
