This test is 1 of several tests that look for HIV infection. Some of these tests take
a few days for results. Rapid HIV tests can give your results in about 20 minutes.
Getting an early diagnosis of HIV is important because you can start treatment early
and also take steps to keep from spreading the virus to others.
Why do I need this test?
You may have this test if your healthcare provider thinks that you have HIV infection.
These are signs and symptoms of HIV infection:
Sudden weight loss
Night sweats or fever
Swollen lymph nodes
White spots in your mouth or throat

People who had unprotected sex with anyone who might have the above risk factors
People who have multiple sexual partners and had unprotected sex with any partner
You may also have this test if you are pregnant or plan to become pregnant.

What do my test results mean?
Test results may vary depending on your age, gender, health history, the method used
for the test, and other things. Your test results may not mean you have a problem.
Ask your healthcare provider what your test results mean for you.
Rapid tests for HIV change color if they detect antibodies that your immune system
has created against HIV infection.
Normal results are negative. This means that no antibodies were found and that you
may not be infected with HIV. Most people who become infected with HIV will develop
antibodies to the virus within 2 months. During this time, you may have HIV but this
test can't detect it. You may want to repeat the test more than 3 months after your
possible exposure if your results are negative.
A positive result means that HIV antibodies were found and that you may have HIV.
You may get a false-positive result. This means there was an error in your test.
How is this test done?
Rapid HIV testing is done with a sample of either blood or saliva. For a blood sample,
a needle is used to draw blood from a vein in your arm or hand. For a saliva sample,
your healthcare provider will rub a special swab against your gums.
Does this test pose any risks?
Having a blood test with a needle carries some risks. These include bleeding, infection,
bruising, and feeling lightheaded. When the needle pricks your arm or hand, you may
feel a slight sting or pain. Afterward, the site may be sore.
What might affect my test results?
Having the test too soon after you are infected with HIV may give you a false-negative
result. This means there was an error in your test.
How do I get ready for this test?
You don't need to prepare for this test. Be sure your healthcare provider knows about
all medicines, herbs, vitamins, and supplements you are taking. This includes medicines
that don’t need a prescription and any illegal drugs you may use.
