Talking about home testing for HIV

Tell your story




Could anything else have affected result?

I took your biosure test at 12 and 15 weeks following a possible exposure and although I recieved negative for both tests I still find myself worrying that they could be wrong. I have a few questions to help ease my mind please?

1. Are your tests affected by anything? I have a hormonal IUD and I’ve had covid and I’m deathly scared that that and anything else could have affected my result? I’ve often read that they aren’t affected by outside circumstances but I can’t stop my mind from wandering….and I’m really scared.

2. Can I trust my negative result?

Your advice would be greatly appreciated so I can move on with my life

Hi JJ, I believe that your negative results with the 4th and 5th gen tests are conclusive as these tests usually have a window period of 4 weeks. But I would double-check with the clinics that performed the tests just to be sure. Hope this helps, Becky

Hi I had unprotected oral sex and tested for HIV in the lab on 10, 13, 37 (instant 4th generation test), 41and 47 (lab-based 5th generation test). I got flu, sore throat, running nose on the 59th day. Do I still need to take HIV test ? Are my tests conclusive?

Hi Help1.0, An IUD would not interfere with antibody production. It has been proven that around 99.9% of people will have produced detectable levels of antibodies by 12 weeks. No need to apologise, happy to put your mind at ease... you're totally right, Google is my enemy when it comes to self-diagnosis! But yes, you can try to put this behind you and move on as your negative results are both extremely accurate and you do not need to retest. All the best, Becky

So having an IUD wouldn’t have impacted my antibody production? I’m just worried that I maybe hadn’t produced enough antibodies by the 15 weeks? So I can trust my result and move on? So sorry to bother with all the anxious questions- my mind ha just been running wild and googling hasn’t helped at all!!

Hi Help1.0, 1. There is no evidence to suggest that an IUD or previous COVID infection could interfere with the results of the tests. The only type of medications that are known to cause cross-reactivity are antiretroviral treatments for HIV. 2. Both of your negative results at 12 and 15 weeks are extremely reliable and are in fact conclusive which means that you do not need to retest. You can rely on your negative results. Hope this helps. All the best, Becky
