Good evening! I'm pregnant at 32 weeks. I had blood tests for infections and a general blood analysis. At that time, I was treating thrush with antifungal medication. The syphilis test was negative, but the antibody test was positive. I went to see my gynecologist and told her it couldn't be, she said "I don't know". She advised me to go to KVD, maybe someone else has had this. I am very worried. Although I am sure of my husband and myself. If only during blood collection they accidentally took some, then it is unlikely.
