What Does This HIV Test Result Indicate?
Question: Sir
My hiv test is negative it's value is 0.032 if negative why is the value not 0
My hiv test is negative it's value is 0.032 if negative why is the value not 0
Brief Answer:
certain antibody titres give a false positive range
Detailed Answer:
Hi, welcome to HCM, certain antibody titres give a false positive range below which the test is not positive. This is true for your HIV test too. Only if it crosses that range(which will happen if the antibody titres are more and you have an actual infection) the test will be considered positive.
Sometimes if the test is done very early after exposure, it can give a low level.
Also sometimes the basic ELISA test that you have probably done may show an undecided result. To confirm, a Western Blot test which is more accurate may have to be done.
Regards

Brief Answer:
In the HIV test, a sample of your blood is placed at the end of the testing
Detailed Answer:
Hi XXXX,
In the HIV test, a sample of your blood is placed at the end of the testing stick. A chemical, called a buffer, to facilitate the testing process is added.
The chemical causes the antibodies in the blood to flow along the test stick. When they pass over the section with the antigens (known HIV proteins), if there are any antibodies for HIV present then they will stick to these antigens and change colour.
By spectroscopy, the amount of antibodies absorbed by the antigen is calculated.
Sample absorbance is the amount of blood sample that is absorbed.
There is a small range that is standardised and set in each lab, below which the test is considered negative.
Negative does not mean zero.
I hope this answers your question. Regards
