The HIGHER the concentration

The higher the concentration of HIV in semen or genital fluids, the more likely it is that HIV will be transmitted to a sex partner.

To determine the concentration of HIV in semen or genital fluids, a laboratory test called a viral load test is typically performed. This test measures the amount of HIV in a given volume of the person's blood or bodily fluids.

To get an accurate viral load measurement, the following steps are typically taken:

1. A healthcare professional collects a blood sample or a sample of seminal fluid or genital fluids from the individual.
2. The sample is then sent to a laboratory equipped to perform viral load testing.
3. In the lab, the sample is processed, usually through a technique called polymerase chain reaction (PCR), which amplifies the genetic material of the virus.
4. The lab then quantifies the amount of HIV RNA (genetic material) in the sample using specialized instruments.
5. The concentration is reported as the number of HIV RNA copies per milliliter (mL) of fluid or as a log10 value (e.g., log10 copies/mL).

By measuring the viral load in semen or genital fluids, healthcare professionals can assess the risk of HIV transmission to sexual partners. It is important to note that even individuals with undetectable viral load can still transmit HIV, albeit at a lower risk compared to those with higher concentrations. Safer sex practices and the use of pre-exposure prophylaxis (PrEP) can further reduce the risk of transmission.
