HIV Testing: Care Instructions

Skip Navigation

Top of the page

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 virus itself. Some home tests use saliva to check for HIV antibodies. Follow the instructions for these tests carefully.

What do the results mean?

Normal (negative)

  • No HIV antibodies, antigens, RNA or DNA 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, RNA, or DNA were found.
  • If you haven't had an RNA or DNA 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.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and contact your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
