To get tested for HIV, you give a blood sample to a clinic, a laboratory or a nurse who visits you, or you use a self-test with an oral swab or finger-prick. A lab antigen/antibody blood test can usually detect HIV 18 to 45 days after exposure, according to the CDC. Results take from 20 minutes for a self-test to a few days for a lab test.
If the possible exposure was in the last 72 hours, do not wait for a test. Go to a hospital emergency department now and ask about PEP (see below).
What types of HIV test are there?
There are three main types of HIV test, as the CDC explains:
- Antigen/antibody test (4th generation): looks for HIV antibodies and the p24 antigen, a part of the virus. A lab test uses blood from a vein. A rapid version uses a finger-prick. This is the usual first test.
- Antibody test: looks only for antibodies, in blood or oral fluid. Most rapid tests and self-tests are antibody tests.
- Nucleic acid test (NAT, or HIV RNA PCR): looks for the virus itself in blood. It detects HIV soonest. The CDC suggests it after a recent exposure, or for early symptoms with a negative antibody or antigen/antibody test.
How soon after exposure can each HIV test detect HIV?
Every test has a window period, the time between infection and when the test can detect it. The CDC gives these usual ranges:
- NAT (HIV RNA PCR): 10 to 33 days after exposure
- Lab antigen/antibody test (4th generation, vein blood): 18 to 45 days
- Rapid antigen/antibody test (finger-prick): 18 to 90 days
- Antibody test, including most self-tests: 23 to 90 days
If you test inside the window period and the result is negative, test again after the window period for that test. A negative 4th generation lab test 45 days or more after exposure usually rules out HIV from that exposure. Ask a doctor if you are unsure.
Where can you get an HIV test in Dubai?
- At home, at your hotel or at your office: a licensed nurse takes a blood sample and sends it to a laboratory. Medilife offers this 24/7 across Dubai. See HIV test at home in Dubai.
- At a clinic or hospital: a doctor orders the test and a sample is taken on site.
- At a diagnostic laboratory: you give a blood sample at the lab.
- With a self-test: you swab your gums or prick your finger and read the result yourself. A positive self-test always needs a laboratory test to confirm it, as the CDC advises.
How fast can you get HIV test results?
Rapid tests and self-tests give a result in 30 minutes or less, but a reactive result needs a lab test. Lab tests take longer, and the CDC says a lab result may take several days at some locations.
With Medilife, the nurse collects your blood at home and you choose the speed:
- Standard HIV test (4th generation): AED 250, report in 24 to 48 hours
- Fast Track HIV test: AED 450, report in 6 to 8 hours, for a same-day result
- HIV RNA PCR test: AED 1,299, report in 24 to 48 hours, for testing from 10 days after exposure
Prices include the nurse visit. Results are sent privately to your phone or email. See HIV test at home in Dubai to book.
What if the exposure was in the last 72 hours?
Go to a hospital emergency department straight away and ask about PEP (post-exposure prophylaxis). PEP is a 28-day course of HIV medicines that can stop HIV from taking hold. CDC guidelines say PEP should start as soon as possible, and no later than 72 hours after exposure. A test at this stage cannot show if you caught HIV from that exposure, so you will need tests later as well.
What does a reactive HIV test result mean?
A reactive (positive) screening result is not a diagnosis. Every reactive result needs a follow-up test to confirm it. In a laboratory, the follow-up test is often run on the same sample. If you used a self-test or a rapid test, you need a lab test. The CDC explains that only when the follow-up test is also positive does it mean you have HIV.
If HIV is confirmed, a doctor will refer you to an HIV specialist. HIV can be treated with medicines, and testing positive for HIV does not mean you have AIDS.
When should you see a doctor?
- You had a possible exposure in the last 72 hours: go to an emergency department for PEP.
- You think you have early symptoms of HIV after a possible exposure, even with a negative test: see a doctor and ask about an RNA test.
- Your screening test is reactive: see a doctor for confirmation and advice.
- You are pregnant or planning a pregnancy: ask your doctor about HIV testing.
How often should you test for HIV?
Test again after the window period following any new possible exposure. The CDC advises testing at least once a year if you have ongoing risk, such as a new partner or more than one partner. If you are on PrEP, you will be tested regularly as part of your care. For other infections, see how to test for STDs at home.
Frequently asked questions
Can I get same-day HIV test results in Dubai?
Yes. A rapid test gives a result in 30 minutes or less, and Medilife’s Fast Track lab test reports in 6 to 8 hours for AED 450, with the nurse visit included.
Which HIV test is the most accurate?
All approved tests are accurate when taken after their window period. The NAT (HIV RNA PCR) detects HIV earliest, from about 10 days. A 4th generation lab test is the usual choice from about 18 to 45 days.
Do I need to fast before an HIV test?
No. You do not need to fast or prepare for an HIV blood test.
Is an HIV self-test reliable?
Self-tests are antibody tests, so they can miss a recent infection for up to 90 days. You must follow the instructions exactly, and a positive result needs a lab test.
Can I test for other STDs at the same time?
Yes. The nurse can collect samples for HIV and other STDs at one visit. STD tests start from AED 250. See STD testing at home.
