Talking about home testing for HIV

Tell your story





Dear Biosure team,

I recently tested negative with your test.
In these days I am studying for a nursing exam and I red that during capillary sampling squeezing the finger can cause blood hemolysis that could affect laboratory results. I remember that I squeezed a lot because at begininnig my drop was very small. Could this cause a false negative? Thanks

Hi Anna Thanks for getting in touch again. We have studies that show that hemolysis has no effect on the outcome of the test. I hope that this helps. Kind regards Gary

Thank you Gary, to be sure, do you mean that the hemolysis does not affect the reaction between antibodies and reagents? Anna.

Hi Anna Thanks for getting in touch with BioSure. Squeezing your finger to encourage blood flow has been shown to have no affect on your result. As long as you have generated a control line, the upper line on the test strip, this shows that the test has been performed with the correct amount of the right sample. Hemolysis itself has also been shown to have no effect on the test result when read at 15 minutes. I hope that this answers your question. Kind regards Gary Carpenter BioSure (UK) Limited
