Patient's question:
I got married last year. Recently, I've been experiencing lower abdominal pain, especially during my period. I'm very worried it might affect fertility, and I also feel extremely cold and afraid of the cold. Could you please explain what an obstetric NT scan is?Doctor's answer:
It is to check the thickness of the fetal neck translucency, commonly used for prenatal screening, which can help diagnose chromosomal diseases and early detect various causes of fetal abnormalities. If it exceeds 3mm, it often indicates potential issues. Generally, blood tests for screening are conducted between weeks 24 and 28 for those without high-risk factors, while high-risk individuals should undergo screening at their initial consultation. High-risk factors include: advanced maternal age (over 30 years old), pre-pregnancy weight exceeding 60 kilograms, excessive weight gain during pregnancy, a family history of diabetes, a history of smoking, gestational hypertension, or a history of previous adverse pregnancies.
