I read on one post concerning false negative that they can be caused by ‘sticky’ antibodies. I’ve never heard of sticky antibodies. I have taken 2 Biosure tests, well outside the window period and they were both negative, considering the unlikelihood of 2 false negatives can I be confident of the results?

Hi JLP - thanks for your kind comments about the PEBL site! Our aims are to 'keep it simple' - 'keep it anonymous' - 'keep it helpful'. We agree, the Biosure people who post answers to questions and concerns are great - wouldn't it be brilliant if all businesses were as responsible as that??!! With best wishes from the PEBL team.

Hi JLP, yes this answer also applies to your concern. The chances of one test giving a false result is extremely low and 2 is virtually impossible. You should not worry about sticky antibodies, this was just an easy way to explain the mechanism of how the HIV antibodies in various positive samples can vary and is not something to worry about. The fact that you have had two negative test results outside of the window period mean you can be confident in your BioSure test results. I would recommend against testing again as this will only prolong the acceptance of your negative result. I hope this helps put your mind at rest. Kindest regards Francesca Bard, BioSure (UK) Ltd

While awaiting a reply I found this on the site. Can I assume this also applies to my concerns?

Dear Anxiety111 The chances of both of your tests providing an incorrect result are around 1 in a million. We would strongly advise against testing again and you can be confident in the knowledge of your negative HIV status. I hope that this helps. Kind regards Gary Carpenter BioSure (UK) Limited
