When do I qualify for an HIV test?
Anyone who believes that they might have been exposed to an HIV infection is adviced to get themselves tested.
Some people are at a higher risk of being exposed to HIV because their lifestyle involves a higher risk. We recommend that the following group must get themselves tested regularly.
- men who have sex with men (MSM);
- heterosexuals who have had sex with more than one sexual partner in the last 12 months;
- people who inject drugs;
- people who work in the sex industry;
- people whose partner is HIV positive.
HIV tests should be offered in the laboratory in the following situations:
- suspicion or diagnosis of an STD or hepatitis B or C;
- suspicion or diagnosis of tuberculosis;
- attempt or intention to get pregnant;
- first prescription of contraceptives;
- sexual assault;
- in case of signs that indicate the presence of an HIV infection.
It is important to emphasise that if the risk of exposure has occurred in the last 48 hours, the person concerned must immediately report to the emergency department for a consultation and possible prescription for prophylaxis after exposure.
How long must I wait before I do the test to get a reliable result?
The INSTI ® HIV Test can already detect an HIV infection after 21-22 days after infection. Please keep in mind that in some cases it might take 3 months before HIV antibodies can be detected. It is recommended to repeat the test 3 months after a possible infection.
How reliable is the INSTI test?
An incorrect test result may be due to improper use. Extensive research has shown that INSTI is extremely accurate if done properly. It has a proven sensitivity (a measure for the reliability that the test will be positive for people who are HIV positive) of 99.8 %.
The test also has a demonstrable specificity (a measure for the reliability that the test will be negative for people who are not infected with HIV) of 99.5%. So, the test is very accurate but a test that is 100% certain is not available yet. Re-testing in case of a positive result is always necessary and you must also immediately contact your general practitioner.
What should I do in case of a negative result?
The result of the INSTI HIV self-test can be read within 60 seconds, in case of a negative result you will see one dot at the top of the membrane and as pictured in the instructions for use. This means that you have not been infected in the last 3 months. A confirming laboratory test is not necessary, unless you suspect that you have made an error when you did the test. In that case we recommend that you do another test at the GGD (Dutch communal healthcare service) or the laboratory.
If your test is negative it does not mean that your sexual partner or partners is/are not infected with HIV.
What should I do in case of a positive result?
After you have done the test you will see 2 dots in the membrane, as pictured in the instructions for use, in case of a positive result. As the test is not 100% certain, a positive result does not necessarily mean that you are infected with HIV. However, given the high accuracy we recommend that your consult your doctor or go to the GGD (Dutch communal healthcare service). It is very important that you do this as soon as possible. We also recommend that you do not have any sexual intercourse anymore with your partner or partners.
It is important to start with the treatment as soon as possible.
What should I do if the test is inconclusive?
The INSTI HIV self-test is inconclusive if you do not see any dot or 1 dot at the bottom of the membrane, examples for this can be found on page 7 of the self-test booklet that is included in your test kit. We recommend that you buy a new test from your pharmacist.
How often can I use the INSTI HIV self-test?
The INSTI HIV self-test can only be used once and is suitable for one person.
Can I still use the INSTI HIV self-test after the expiry date?
The INSTI HIV test cannot be used after the expiry date.
Are there optimal circumstances for the use of the INSTI HIV self-test?
The INSTI HIV self-test can be used at any time, however it is very important that you read the instructions for use carefully before you do the test.
It is important that you consider before you do the test what you will do in case the result is positive. We recommend that you consult your doctor or the GGD (Dutch communal healthcare service) if the result is positive.
