First test



Do I test again?

Hi – taken biosure test after possible exposure 5 years ago result came back as negative, I see on the forum people take more than one test for single exposure out of the three month window do you think this is necessary thanks.

I thought that you get overall probability by multiplying the two together. If that's true then the chances of 2 tests being wrong are very very small cos that is 2/1000 x 2/1000 which would be 4 in a million. So I reckon you really don't have to worry if 2 tests gave negative results. If it was me I would trust just one test. Good luck to you Bro/Sis - hope this helps.

Hi all - Can you answer my question please about second test and false negative? I saw on the forum where Gary said a few posts ago about chance of a false negative on second test about 250.000 to 1 but on much earlier posts 1 million to 1 are mentioned. Why has this changed? thanks.

Thanks for reply I saw on forum that odds of a false negative are about 2 in a 1000 but if taking second test they increase to 1 in 250.000 but saw on earlier post back in 2016 odds on second test were 1 in a million is this true thanks

Hi First test. There is no need to re-test given that your exposure was 5 years ago. It is only recommended to re-test if your exposure was less than 3 months before you tested. I hope this helps. Kindest regards Francesca Bard, BioSure (UK) Ltd
