What if you are HIV positive but test negative at a later point?
HIV expert Dr Sindisiwe van Zyl says that, generally, if a
person has been on antiretroviral treatment (ARV) for a long time, the HIV
antibodies in their system go down.
If that person were to take an HIV
ELISA fingerprick test, there is a high chance that the test would come back
as negative or the positive line would be extremely faint.
This is why
if someone is on treatment and they say 'they have been healed', she always requests a laboratory HIV ELISA test where blood is taken from a vein
in the arm and sent to a lab.
