Might I have sticky antibodies?

I have done 2 Biosure self tests well outside the window period and both were negative.

I am trying to move on with my life but i continue to have symptoms that i believe are consistent with and specific to HIV infection.

How likely is that i have ‘sticky’ antibodies that are not detectable via 2 biosure tests? Or that i am hiv positive but hiv antibody negative? I have read about people with hiv but constantly tested negative via antibody testing.

As i say i am trying to move on but the ongoing symptoms make me doubt my results and its affecting my mental health.

Thank you

Hi Sid, Sorry for not getting back to you sooner. It is a hard subject to explain as there is little research available regarding their involvement with antibody production. The chances of a test giving a false result is extremely low and our test specifically has been proven to be able to accurately detect infection in 99.9% of people by 12 weeks. Sticky antibodies is simply a term used to explain how the HIV antibodies in various positive samples can vary. An extremely small percentage of people are said to have 'sticky' antibodies and it is not something to worry about. I hope this helps. Kindest regards, Becky

Could you please explain what sticky antibodies are and how they can affect the test. Your answer seems to suggest that they could play a roll in giving false Negatives. Is this the case ?

What are sticky antibodies?

Hi Ethan25, The fact that you have tested twice, both outside of the window period, is extremely reliable. The percentage of those who are said to have 'sticky' antibodies is in fact extremely low. If you were to have been infected more than 12 weeks ago, antibodies would be present in your immune system and therefore will be detectable. The fact that you are still experiencing symptoms is a bold indication that you are not HIV positive as those who have been recently infected will experience symptoms within the first few weeks of infection. After the seroconversion period, infected individuals will become asymptomatic and therefore will not experience symptoms related to HIV infection. I am confident in saying that your 2 negative results are reliable, given that you have tested outside of the window period on both occasions. I know that it can be hard to trust your results but you must try to move on from this knowing that you are healthy and HIV free. I really hope this helps, if you have any other questions, please feel free to leave them below. Thanks, Becky.
