Hi again, my husband tested positive to the anti Cw and anti E antigens and I have been getting monthly blood tests. The results have been very positive and the titres are as low as can be detected and less than 1. They haven't risen throughout the pregnancy. I just received the latest results and it said "antibody non reactive by iat". Just wondering what this could mean for me. Can antibodies be low one day and higher the next? I am yet to find a dr who can fully explain these results or antibodies and this site has been invaluable. Any information would be greatly appreciated! Thank you Kelly
