Hi everyone I just had a call from my doctors surgery asking me to come and do repeat bloods in 4 weeks (Ive just had 12 week scan and bloods approx 2 weeks ago) my nuchal results came back with low risk for downs so I was just wondering why they would test again in 4 weeks? Its my first pregnancy so not sure what is normal or not! The receptionist didnt know why she suggested I could be borderline but borderline what? Has any of you ladies had this or much experience of blood tests? Thanks
