Talking about home testing for HIV

discolored/white T line?

I’ve made a HIV rapid test. I put a smaller than required amount of blood and the right amount of buffer. For unknown reasons the buffer run through the strip immediately after I dropped with no blood. After 10 minutes no control line showed up and a discolored “line” (white indeed) showed on test area. After 45 minutes (longer than the reading time) there was a light control line and the discolored “line” was still at the test area. I brushed my finger on the strip and the control line kept but the discolored white line disappeared.
I think that this test did not work properly. I bought two other tests from the same manufacturer and both worked properly coming out as non reactive (negative).
My question is “what did that discolored/white T line mean?”
Thank you in advance!

Hi AJ, unfortunately I am unable to comment on your test as I do not have enough knowledge. My advice would be to contact the manufacturer / place where you purchased the tests to get answers to your questions. I would also like to highlight that you should only be testing with products that are approved for home testing/self testing - this is usually a CE mark that can be found on the box. If you wish for me to help you further I would recommend testing with BioSure (available on, amazon or selected Superdrug and Boots stores) otherwise I hope you manage to get answers to your questions. Kindest regards Francesca Bard, BioSure (UK) Ltd
