HIV antibody tests
If more than 3 months have gone by then an antibody test is sufficient. Detection is extremely high with these tests (up to 99.99%)
We can do these tests either here in Madrid or in your local blood collection centre.

Can I do this test from home?
Unfortunately we can’t do this test from home. There are other HIV tests that we can do from home, such as the test we do after 3 weeks.

Can I do this test without going to Madrid?
Yes, we can organize for your blood to be taken in a clinic in your region (subject to availability). They will send us your blood for testing at Open House and then we will get the result back to you by email within 48h of receiving your sample.

Just 3 to 4 weeks have gone by

After 3 weeks there is a test you can do at home.
If three weeks have gone by then you can do the PCR test from home!!
This test looks for the genetic material of the virus and all it requires is for you to collect your own dried blood sample. The test is very sensitive if three weeks have gone by and will detect just 1000 copies of the virus in every millilitre of blood. The detection with this test after three weeks is calculated to be around 99.9%. And all with the convenience of testing from home. With this result there is no need to wait out the standard 3 month window period.
You buy your kit online. When it arrives it explains how to take your sample which is quick and easy. When the blood sample is dry you just send it back to us by handing in the return envelope at the Post Office. We will send you the results by email in just 48 working hours once we receive your sample.
Do you need a medical consultation? We can organise a phone consultation before or after you do the test

Just 10 days have gone by

If only 10 days have gone by then you can do the sensitive PCR test.
This test looks for the genetic material of the virus. The test is very sensitive if 10 days have gone by because it can detect just 300 copies of the virus in every millilitre of blood. The detection with this test after 10 days is calculated to be around 98%.

Can I do this test from home?
Unfortunately we can’t do this test from home. There are other HIV tests that we can do from home, such as the version of this test we do after 3 weeks.

Between 3 and 10 days

If three days have now gone by then the possibility of administering “shock treatment” is no longer an option (see the next section). But if you still haven’t reached the 10 days cut-off point then we are unable to do the PCR test (see the previous section)
You will have to wait a few more days which may seem like a torture to you, but in our experience when most people read for the first time what the true risks of HIV are in each kind of sex (oral, vaginal and anal) they feel calmer.

If you’re not sure if the sex you have had is considered a risk for HIV, this information is available in our website.

Less than 3 days ago

If 3 days have still not gone by since the last high risk contact, a possibility exists which consists in administrating anti-HIV mediation to dramatically reduce the possibilities of infection. This treament is not for everybody, nor for all kinds of sexual contacts but ….

– if you have had vaginal or anal sex with someone who you know has HIV
– if you have had passive anal sex with someone with an unknown HIV status

….it may be possible that you are a candidate. You need to go to the Emergency Room in the first 72 hours and ask for their help.
