HIV Testing: Care Instructions

Overview

You can get tested for the human immunodeficiency virus (HIV). Most doctors use a blood test to check for HIV antibodies and antigens in your blood. It may also check for the genetic material (RNA) of HIV. Some tests use saliva to check for HIV antibodies. But these aren't as accurate. For example, they may give a false result if you've just been infected.

What do the results mean?

Normal (negative)

• No HIV antibodies, antigens, or RNA were found.
• You may need more testing. It can make sure your test results are correct.

Uncertain (indeterminate)

• Test results didn't clearly show if you have an HIV infection.
• HIV antibodies or antigens may not have formed yet.
• Some other type of antibody or antigen may have affected the results.
• You will need another test to be sure.

Abnormal (positive)

• HIV antibodies, antigens, or RNA were found.
• If you haven't had an RNA test yet, one will be done. If it's positive, you have HIV.
• If your test result is positive, your doctor will talk to you. You will discuss starting treatment.
