Patient's question:
I have an itchy lower body, and my underwear is always yellow. What's going on? Can I eat papaya yogurt during my period?Doctor's answer:
You can have the Down syndrome screening between weeks 14-18 of pregnancy. The Down syndrome screening is a non-invasive test method for the fetus, which is economical, simple, safe, and conducted between weeks 14-18. It only requires 2 milliliters of blood drawn from the pregnant woman's vein after fasting for 12 hours. The results will be available 2-3 weeks after the blood draw. If the serum screening is positive, further amniocentesis is needed to confirm the diagnosis and determine the treatment plan. The Down syndrome screening can also detect high-risk pregnant women for neural tube defects, 18-trisomy syndrome, and 13-trisomy syndrome. You cannot eat or drink during the Down syndrome screening.On the other hand, the 4D ultrasound is performed between weeks 22-26 of pregnancy for a 4D color Doppler ultrasound to check for fetal abnormalities and the development of major organs.
Therefore, the above two tests are based on the duration of the pregnant woman's gestation.
