What The Rapid Hiv Test Involves
You finger will be pricked with a needle. The drop of blood that is produced is mixed with chemicals and the result will be known in just a few seconds. Results from the rapid test are considered to be very reliable, but if your result is positive, a normal blood sample will always be taken and sent to a laboratory for analysis.
During an initial discussion, you will be told that the result of an HIV test is about 80% certain around two to three weeks after you become infected. Not until three months later will the result of the test be 100% certain. Any questions you may have about the test will also be answered.
What Happens When You Go For A Test
Normally, testing involves taking a small sample of blood from your finger or your arm, or an oral swab. This is where you rub the testing pen along your gums to collect cells from your mouth.
How long it takes for HIV test results to come back will depend on the type of test you are taking. If youre taking a rapid test, you will be given your results within 20 minutes. Other types of tests will be sent to a laboratory and it may take between a few days and a few weeks for you to receive a final result.
Tests these days are very reliable, but if your result comes back positive, you should have a second confirmatory test to double check your result. If this is also positive, you will get an HIV diagnosis, after which you can start treatment.
Remember, HIV treatment these days is very effective and people with HIV can live long and healthy lives just like anyone else.
Window Periods Of Rapid Tests
The window period refers to the time after infection and before seroconversion, during which markers of infection are still absent or too scarce to be detectable. Tests cannot reliably detect HIV infection until after the window period has passed. All tests have a window period, which varies from test to test.
Delaney and colleagues estimated window periods for a handful of rapid tests in a 2017 study. However, all these estimates were based on testing blood plasma. In practice, tests are usually done on fingerprick blood and the window period is likely to be several days longer.
The fourth-generation Determine HIV-1/2 Ag/Ab Combo was estimated to have a median window period of 19 days . This indicates that half of all infections would be detected between 15 and 25 days after exposure. Ninety-nine per cent of HIV-infected individuals would be detectable within 43 days of exposure.
The third-generation INSTI HIV-1/HIV-2 test was estimated to have a median window period of 26 days . This indicates that half of all infections would be detected between 22 and 31 days after exposure. Ninety-nine per cent of HIV-infected individuals would be detectable within 50 days of exposure.

How Long Does An Hiv Test Take
How long does it take to get results from an HIV test?
Waiting for test results can certainly be stressful â and while the past few decades of research on human immunodeficiency virus and acquired immune deficiency syndrome have made great advances in testing technology, its tough to give an exact estimate of how long it takes to get test results. There are many factors to consider, including: the type of HIV test completed, how long it takes for a particular community health center or lab to analyze and report the test result to the patient, and how long someone has waited to get tested after an exposure . Also, sometimes the results must go through a health care provider first, who will then relay them to the patient, which can take more time. The good news is that many testing options are fairly quick. While the most rigorous lab-based tests can take several days to produce a result, some rapid tests can take as little as 20 minutes.
In general, the turn around time for HIV testing depends on the type of testing performed. These tests include:
- NAT: 10 to 33 days after exposure
- Laboratory antigen/antibody test: 18 to 45 days after exposure
- Rapid antigen/antibody test and antibody self-test: 18 to 90 days after exposure
Hereâs hoping you didnât have to wait long to get results from this response!
What Are The Rapid Hiv Test Options

Can Hiv Be Prevented
There is currently no vaccine to protect you against HIV, but avoiding high-risk activities such as having unprotected sex and sharing needles for injecting drugs can help to prevent its spread.
While there is no vaccine, the CDC and the World Health Organization recommend that individuals without HIV infection but at high risk for it consider taking pre-exposure prophylaxis , a daily pill to help prevent infection. For people taking PrEP consistently, the risk of HIV infection was significantly lower compared to those who didn’t take it.
If you have HIV, early diagnosis of your infection is important to prevent its transmission to others and to allow evaluation, monitoring, and treatment. Healthcare workers can protect themselves from HIV infection by following universal precautions, such as wearing gloves and avoiding needle sticks.
Post-exposure prophylaxis is another strategy for preventing HIV. PEP is taking antiretroviral medication after recent possible exposure to the virus. PEP should only be used in emergency situations and must be taken within 72 hours of possible HIV exposure. Talk to your healthcare practitioner or emergency department doctor about PEP right away if you:
- Think you have may been exposed through sex
- Think you were exposed through sharing needles or other works for injecting drugs
- Were sexually assaulted
- Are a healthcare worker and think you were exposed to HIV at work
How Can Someone Test For Other Stds At Home
People can test for other sexually transmitted diseases , such as gonorrhea and chlamydia, using home testing kits. These tests usually consist of taking a urine sample or a swab from the genital area and sending it to a lab facility for testing.
The test should be repeated if a person received negative results, but theyre experiencing STD symptoms.
Another option is to have a healthcare professional order another test to ensure that the results are accurate.

Making Hiv Testing Routine
You might want to test more regularly than this, for example, if you are having sex with a new partner or feel you are more at risk. Groups who are more at risk are recommended to test more regularly. Testing every 3-6 months is often advised for men who have sex with men.
Testing regularly helps keep your mind at rest, and if you test positive, it means you can start treatment quickly, protecting your health.
Im Pregnant When Should I Test
Testing for HIV during your pregnancy is very important. Left undiagnosed and untreated women living with HIV can pass the virus on to their unborn babies. In most countries, HIV tests are a routine part of the care women receive during pregnancy . Partners of pregnant women should also get tested during this time.
The earlier you test in your pregnancy the better. You’ll usually be tested in your first appointment, ideally before your tenth week. These tests should be repeated, either every three months or at least once again in your third trimester.
Your doctor will tell you everything you need to know about HIV testing alongside the other blood tests they do during pregnancy.
If you find out you are positive, youll be given treatment to prevent passing HIV on to your child. The earlier you start treatment, the greater the chance your child will be born HIV-negative. Check out our section on Pregnancy, childbirth & breastfeeding for more information.

THE IMPORTANCE OF TESTING
Sex without the use of an effective HIV prevention tool or sharing injecting equipment are all activities that can put you at risk of HIV by allowing bodily fluids or vaginal fluid) to enter your body, and possibly your bloodstream.
The only way to know your HIV status is through testing. Testing for HIV is important because it enables the individual to know their status, seek treatment and support if necessary and take steps to prevent onward transmission.
Being tested regularly for HIV is simple, quick and made convenient with multiple testing sites in major cities and towns across Australia. Testing is also available through general practitioners.
There are also a number of community-based testing services around the country, including those that are led by peers.
REGULARITY IS KEY
Gay men and other men who have sex with men are recommended to have a comprehensive sexual health check at least twice a year, and up to four times a year if they are in one or more of these categories:
- have had any condomless anal sex
- have more than 10 sexual partners in 6 months
- participate in group sex
- use crystal meth.
UNDERSTANDING HIV RAPID TESTING
Traditional HIV testing, where blood is drawn and sent to the laboratory for testing can take several days or more to get a result. Rapid Testing uses a pinprick of the finger and returns results within 10 to 20 minutes.

SIGNS & SYMPTOMS
What Are The Treatments For Hiv/aids
Currently, there is no cure for HIV infection or AIDS. However, early diagnosis allows for treatment with antiretroviral therapy that can help to suppress levels of virus in your body and greatly improve your long-term health. The U.S. Department of Health and Human Services as well as the World Health Organization recommend that all individuals diagnosed with HIV infection receive treatment as soon as possible, including pregnant women. With advances in treatment, individuals with HIV infection are living longer, healthier lives.
People typically take at least three drugs from two different classes in order to prevent or minimize virus replication and the emergence of drug-resistant strains. Combinations of three or more antiretroviral drugs are referred to as highly active antiretroviral therapy or HAART. Read the Treatment section of the article on HIV Infection and AIDS for additional details.

The Accuracy Of Different Rapid Tests
A wide range of point-of-care tests have been manufactured in many countries, but only a few of them have been subject to rigorous, independent evaluations, and even fewer are marketed in the UK. Research on HIV tests is only occasionally published in medical journals. Informally, laboratory professionals may have insights into which tests perform best.
It is important to verify that any test used is CE marked. This should mean that the test conforms to European health and safety legislation, although it does not necessarily mean that test performance has been independently evaluated.
There are variations in accuracy from one test to another, with some older tests that are not usually marketed in the UK having a sub-optimal sensitivity and specificity. However, evaluations by the World Health Organization of several rapid diagnostic tests that either have CE marks or are approved by the US Food and Drug Administration , indicate that most are extremely accurate. The key measures of accuracy are sensitivity and specificity .
Of note, in the World Health Organization data below, the tests were performed with samples of plasma or serum. However, the tests are less sensitive when testing whole blood sampled from a finger prick. Moreover, the blood was taken from people who had chronic HIV infection, but the tests are less accurate in cases of recent infection.
“All HIV tests need to have reactive results confirmed with further tests.”
What Are The Advantages Of A Rapid Hiv Test
The rapid test allows for testing of more individuals. According to the CDC, 1.2 million Americans have HIV, but up to one in eight don’t know it. About 44,000 Americans per year become infected with HIV. This number has decreased recently due, in part, to more testing. Among those who get tested using traditional methods, 31% of those who test positive do not return for their results .
People give a variety of reasons for not returning for their test results. The frequency of each response depends on the population being tested. The most commonly given reasons include the following:
- Fear of a positive result
- Lack of transportation
- Relocating to a new city
- Belief that they are at low risk for HIV and therefore the result will be negative
- Fear that their HIV status will be disclosed to someone else
Significant benefits of the rapid HIV test include the following:
Once important difference between the conventional laboratory test and rapid tests is the ability to detect very early or acute HIV infection. This is done with the addition of an HIV RNA PCR or NAT test. HIV RNA appears in the blood within the first few days of infection. If the antibody test is negative but the NAT is positive, this may indicate that the patient is very newly infected. NAT testing is also used to confirm a positive result of the third- or fourth-generation test. Western Blot testing is no longer routinely used.
