Pregnant and indeterminate, please help!

Hi, I am 32 weeks pregnant.  I have been in an exclusive sexual relationship with my husand for one year (married for 5 months).  A few weeks before we got together a year ago, I had a casual,unprotected encounter with a white male, and I have not thought much about it until now.  I was tested for HIV at my first prenatal visit, and the result was negative (6 months post possible exposure with the random guy).  New laws in Texas require 3rd trimester testing, so I was surprised to find that my results from this test (11 months post possible exposure) were ELISA reactive, Western Blot indeterminate.  My husband has tested negative (last week).  How is this possible??!?!  What are the chances my indeterminate will become positive?  Please help!

Were you advised that you could test positive on the ELISA and Western Blot because you are pregnant? It's normal...

No, no one told me that. Is it possible that I am still in the seroconversion process?

[Teak]

NO.

Thank you, Teak, for the info. My husband and I have been flipping out. I want to strangle my doctor now. He actually sat there and told me I was positive without explaining what "indeterminate meant."I was so confused and upset. He now refuses to see me, and has sent me to a high risk OBGYN.

Sounds like a good move to see another doctor. Congrads on the up coming birth and good luck on further testing.

I work in a lab so understand the process a bit. The westernblot is more specific and serves to confirm the ELISA result. It kind of also depends on how high the reactivity was on the ELISA test. If the reactivity was low like around 3 or 4 units, then it could have been a false positive. However, if it was >50, it probably was not a false positive.

We send out positive ELISA tests all the time and the westernblot mostly comes out positive or negative. An indeterminite definitely needs a retest to confirm the ELISA test. While it may have been due to your pregnancy, running a second test with the same results would most likely be accurate.

All positive test have to be confirmed.

My second WB came back negative, and so were the DNA/PCR and CD4! : )  To all you preggos out there, rest assured--it's the TEST!!!  What a heart attack for no reason!
