Hello doctors. I am having thyroid and pcos. I was diagnosed with high blood pressure, gestational diabetes too in my last pregnancy due to which my baby couldn't make it long and fetal heart stop beating at 32 weeks of gestation period all because of IUGR. Baby weight was 350gms only. I had a normal delivery then. Its almost one year now and I am trying to conceive again but having 3 failed cycles. Ovulation does take place at day 13 or 14 but I am not able to conceive. This time my doctors prescribe me few test- FDS, TSH, AGS, TORCH (igg & igm), HIV for both husband and wife, VDRL for both husband and wife, ESR, GLYCOSYLATED Hb. What are these test for? And what is the difference between FDS & RDS? Bcz I think my doctor misspel it. On one prescription she has written RDS and on other lab prescription FDS? Both test are same or different?
