HIV Viral Load Test
HIV Viral Load Test
Test Overview
A viral load test measures how much HIV is in the blood. It's first measured when you're diagnosed with HIV. This serves as the baseline. Future measurements are compared with it. With treatment, the viral load should go down. Within a few months, there should be very little virus in your blood.
Why It Is Done
Why It Is Done
A viral load test is done to watch for changes in an HIV infection. Your doctor uses it to see how well your treatment is working. This information helps guide your treatment options.
A goal of treatment is to reach an undetectable viral load. This means that the amount of the virus is too low for the test to detect. When the virus is undetectable, you cannot pass HIV to other people through sex.
How To Prepare

In general, there's nothing you have to do before this test, unless your doctor tells you to.
How It Is Done

Results
Results
Each lab has a different range for what's normal. Your lab report should show the range that your lab uses for each test.
Viral load results are reported as the number of HIV copies in a milliliter (copies/mL) of blood. Each virus is called a "copy," because HIV reproduces by making copies of itself (replicating).
HIV viral load
|
Normal:
|
HIV is not detected (undetectable) in the blood.
|
|
Abnormal:
|
HIV is detected in the blood. Your doctor will compare your current measurement with previous values.
|
If the viral load drops, it means that the infection is being suppressed or controlled.
If no HIV copies are found, this does not mean that you don't have HIV anymore. It means that the amount of HIV in the blood was too low for the test to detect.
