The Test Sample
|
| |
What is being tested?HIV, human immunodeficiency virus, is the virus that causes AIDS (acquired immunodeficiency syndrome), which destroys the immune system and leaves the body vulnerable to debilitating infections. This test detects HIV antibodies in the blood. Antibodies to HIV are produced by the body and can be detected in the blood about 2–4 weeks after exposure to the virus.
How is the sample collected for testing?
Blood is drawn through a needle placed in a vein in your arm. There also are tests available that can be performed on urine and/or oral fluid.
NOTE: If undergoing medical tests makes you or someone you care for anxious, embarrassed, or even difficult to manage, you might consider reading one or more of the following articles: Coping with Test Pain, Discomfort, and Anxiety, Tips on Blood Testing, Tips to Help Children through Their Medical Tests, and Tips to Help the Elderly through Their Medical Tests.
Another article, Follow That Sample, provides a glimpse at the collection and processing of a blood sample and throat culture.
