Hi Andy77 ** this response is also on the dedicated site, please go to:- PEBL HIV SELF TEST Thanks for getting in touch with us. After the window period has elapsed (which is the period in which HIV infection cannot be detected by a class of test devices, in this case 3 months) a negative result from a BioSURE HIV Self Test is very accurate, greater than 999 times in every 1,000 negative results. You should consider your HIV status to be negative. The symptoms you describe are not indicative of HIV and the exposure described would have been too soon to have caused any damage to your immune system. I would advise getting the symptoms described checked out by your GP, but you can go to that appointment confident in the knowledge that they are not as a result of an HIV infection. I hope this answers your question. Kind regards Gary Carpenter BioSure (UK) Limited
