Hiv Duo is Positive - Western Blot is Indeterminate

I decided to test on 28th day. ...

Vidas Duo test and result is :

ELFA (HIV Duo ULTRA -VIDAS)
RESULT (HIV 1/2 Ab) : POZITIVE
PATIENT VALUE: 0.48
Cut-off : Negative <0.25 T.V.
RESULT (HIV p24 Ag ) : NEGATIVE
PATIENT VALUE: 0.00
Cut-off : Negative <0.25 T.V.

then lab. validate with WB (same sample of blood).

the result is : INDETERMINATE (only p31 band positive)


What does mean ? Am I HIV patient ?

Please give me suggestions and ideas....

Since your last reply was over 2 years ago, I am wondering whether you have got confirmation of your HIV status.
I'm working in laboratory, on HIV testings, and sometimes the results for HIVDUO are positive, slightly above cutoff value, like your result. Just once we have got a feedback from one old granny, who was also found to be positive, but confirmation tests turn out to be negative, and she told us that she had received a vaccine against flu that winter before first HIV testing, so we're thinking that might be an interference. Do you remember doing anything similar in that period? That might be very helpful information for me.

this result belongs to hiv duo.

but our result is 0.48 , means positive.

State your exposure so we can help determine your risk. I don't understand how 0.48 is considered positive. What I know is anything above 1 is positive.

Is there any relationship between EBV (infectious mononucleosis) and p31 band ?

perhaps your infection was acquired from a different episode hence the antigen part is no longer positive. correct me if I'm wrong. your interdeterminate WB is nothing to worry about now. Wait for 3 months and test again with an antibody test. Take care.
