Question

Why do I have a number on my negative test result?

28 August 2016. Related: All topics, HIV testing.

I have taken an HIV test and my index value is 0.08 which is negative, what does this mean?

Answer

Answer: Muirgen Stack

Some tests (not usually in the UK) include a number (ie 0.31 or 0.64).

  • If the number is less than 1.0 the result is negative.
  • If the result is above 1.0 the result is positive
  • If the result is very close to 1.0 (higher than 0.90) the doctor may repeat the test.

A higher number below 1.0 does NOT indicate a higher chance of having HIV.

    I have a low risk result. I dont sleep with other people. I can’t understand how this is possible. I have done the retest. What is the chance of it being positive?

    Hi, firstly you didn’t have sex that would put you are risk. Secondly, the tests show you are both HIV negative. Please take time to read about HIV and risk so that you can enjoy sex more freely in the future. Info about testing and transmission is linked to this answer:
