Multiplex Early Detection

The multiplex test is a blood test, and is sometimes also referred to as a ‘PCR’ test (polymerase chain reaction), or NAAT (Nucleic Acid Amplification), which works by analysing DNA to detect tiny amounts of viral genetic material. It is the test that can be taken soonest after exposure to the HIV virus (a minimum of 10 days), as early detection is key in preventing the spread of these infections and ensuring effective treatment. Multiplex testing is particularly beneficial among sexually active populations, where the risk of exposure to multiple STIs is higher.

You will need to come in so that we can take a blood sample. Trace amounts of DNA from the sample are then amplified and compared to the virus’ own unique DNA sequence.

The test is highly sensitive and highly accurate, and your results will be available within a week.

How is the Multiplex PCR test different from the antibodies test?
The Multiplex PCR test detects the presence of genetic HIV material, rather than antibodies. Multiplex testing locates the DNA copy of the HIV virus itself. This is usually present sooner than the antibodies that the body produces in response to an infection.
How accurate is the Multiplex PCR test in detecting HIV?
Recent research suggests that the Multiplex test is 98% accurate if taken 10 days after exposure.
Is the test painful?
Multiplex testing is done using a blood sample, so the test procedure is no different to other sexual health blood screenings. The blood test is quick and relatively painless; you may feel a slight scratch or pricking feeling when the needle is inserted.
