Hi XXXXX,

Thanks for writing in.

Diarrhea can be caused by multiple causes like bacterial/viral /parasitic infection.
HIV is not the only cause in diarrhea.

CMIA/DUO rouche ASSAY is very dependable test after 28 days.

Negative result rules out the HIV infection. Also the very fact that your exposure was with known person reduces the risk .

Still it has to be repeated after 3 months to be absolute confirmation.

Your symptoms are unlikely to be due to HIV and you can relaxed about it.

Diarrhea in HIV is seen in late stages and is persistent for weeks together.

It is very unlikely in your case.

Hope this helps you .

Hi XXXXX,

Thanks for details.

White tongue can be due to candidiasis (fungal infection)or coated tongue (due to dehydration or diarrhea etc).

Candidiasis can be associated infection with HIV, whereas coated tongue is common in dehydration and diarrhea.

So you should not worry about the symptoms and get tested for HIV at 28 days.

Risk is very low in your case as the partner was known.Repeat test will confirm the negative status.
Hope this helps.

Hi ,
You should take the test on 28th day only.Although it does not make much of difference by a day or two but for safe side you should get tested on 28th day itself.
If you are satisfied with the answer you can accept it and rate it at the end.

hi Doctor ,

thank you for your reply .
i got tested today, last month may 27th morning around 8 clock i had exposure.
today i tested, result was negative. index value remains same .43 .

report contains HIV combo(ROUCHE) .43 COI below mentioned as non-reactive.
method :CMIA/DUO.

how accurate is this result, because i en-quired lab technician who do no know any information about this whether it contains antigen detection or not. she told only antibody. i ask general physician, he also mentioned the same. but in the report they mentioned CMIA/DUO. how much accurate is this report, i will redo the test at 6 week ,8 week and 12 weeks.

i am little depressed , not able to predict. people are not answering my question.

i attached my test report as well

Follow up: Dr. Sudarshan (1 hour later)

do you suggest me to take another test tomorrow by another method called ELFA
or CMIA is the best method.

i did CMIA test at 20th day and 28 day exposure, that is today, index value is .43 which remains same. is it good indicator or bad one ?

please guide me

Hi Again,
Sorry for replying late but I had busy schedule.

The Chemiluminscence (CMIA) HIV test is extremely accurate and reliable, and most CMIA tests include detection of the p24 antigen, which allows for earlier HIV infection detection. This is because an exposure which leads to an infection can take up to 3 days & P24 antigens are detectable immediately after infection, until your body's antibody response takes over (at which time the antibodies bind to the antigens, making them no longer detectable). However, not all CMIA tests may include p24 antigen detection, so retesting at 12 weeks is suggested.

While I do not expect your "non-reactive", or "negative" results to change, As HIV specialist I do recommend re-testing at 12 weeks.
The index value 0.43 does not hold any significance,its not indicator at all.

Hope this clears your doubt.
