Question: Rubella positive with high avidity
|shi_81 - Tue May 25, 2010 5:57 am||
am 28 yrs old and 8 weeks pregnant. and I am rubella positive with high avidity.
Rubella IGG : 150.95
RUBGELLA IGM : 1.79
RUBELLA AVIDITY : 90%
Is it safe to carry the pregnancy.
It is my second pregnancy. First one was aborted because of rubella itself (last year april'09). after that I was vaccinated (RVAC) in may'09.
My gynea said as avidity is high rubella will have neglligible effect but we are still very confused. Please help us out.
Your early advice will be of great help for us.

As time goes by following rubella infection, avidity increases. Along with a low IGG (<10IU/mL), reinfection might be possible but if IGG is high, it would indicate immunity to the disease. Yours is >150 (I assume IU/mL) so I think you are at low risk for any fetal consequence. The levels are showing immunity; not infection. Had you been immunized prior to becoming infected? In other words, did your immunization fail you or had you never had the vaccine before? Some people are not able to develop immunity but if I am understanding these values correctly it does not appear to be the case.
It never hurts to ask your doctor to further explain the meaning of the labwork.
