window period

[lauraEG022483]

I had a test at six weeks and ten weeks.  Both were negative.  I guess I need one more to meet the three month window period.  However, I am not sure if twelve weeks or thirteen weeks would be considered conclusive.  three months can be interpreted as either.  I will be 36 weeks pregnant at the twelve week mark and would like to go ahead and do the test.  The longer I wait the more chance I have of going into labor without a conclusive result.  My doctor doesn't seem to know about the other types of testing available.  They are using the LabCorp HIV 1/0/2 ICMA antibody test.  I can't get a lot of information on this test. I know it is not an ELISA and that really bothers me.  I had a full std panel done at 6 weeks from exposure and then an hiv only test at ten weeks. I am going to ask for another full std panel at 12 weeks to include another hiv antibody test.

1. For hiv, is 12 weeks conclusive or do I need to wait until 13 weeks?
2. Is Labcorps ICMA hiv 1/0/2 ICMA antibody test as sensitive and accurate as a 3rd generation ELISA?
3. Is it likely that a negative 10 week test will change or should I feel pretty confident that my results will still be negative?

thank you for your input.

The US uses 13 weeks all others use 12 doesn't really pose a difference.

Either is conclusive.

thank you Teak.  Is twelve weeks considered conclusive or thirteen weeks?  Three months confuses me because I am not sure if that is considered 12 or 13 weeks.

You can feel confident but your conclusive negative test result is 3 months post exposure.

1. Either 2.YES 3.NO 4.You should feel extremely confident that your results will be negative again.
