HIV Viral Load
What is HIV Viral Load?
HIV viral load tests measure the amount of HIV in a person's blood. These tests are important for monitoring the effectiveness of medication in managing HIV infection.
Preparation for an HIV Viral Load Test
Testing for HIV virus is usually done when the patient is hospitalized or has a confirmed diagnosis. Generally, no special preparation is needed for an HIV viral load test.
Procedure For HIV Viral Load Test
An HIV viral load test is performed by taking a small sample of blood from the patient. The blood is then sent to a laboratory for testing. The laboratory will measure the amount of HIV virus in the blood sample using a technique called polymerase chain reaction (PCR). PCR can detect even small amounts of the HIV virus in the blood.
Types of HIV Viral Load Tests
- Quantitative HIV-1 viral load tests: These tests measure the amount of virus in a person's blood. They are often used to monitor the response to HIV treatment.
- Qualitative HIV-1 viral load tests: These tests detect the presence of the HIV virus but do not measure the amount. These tests are usually used to diagnose HIV infection.
Risks of HIV Viral Load Tests
There are no known risks associated with HIV viral load tests. The test is performed by taking a small blood sample, which may cause some minor discomfort.
When To Get An HIV Viral Load Test?
HIV viral load tests are typically ordered as part of routine care for people with HIV infection. For people who have recently been diagnosed with HIV, the test may be ordered in order to measure the amount of virus in the blood. For people who are already on HIV treatment, the test may be performed to monitor the effectiveness of the treatment.
Why Get An HIV Viral Load Test?
HIV viral load tests are important for monitoring the progress of HIV infection. By measuring the amount of virus in the blood, doctors can determine if the treatment is working and if the HIV virus is under control. Knowing the amount of virus in the body can also help guide decisions about when to start or switch HIV treatments.
