Patient's question:
From the time of conception to now, nine weeks have passed. I've heard that after getting pregnant, one needs to undergo a Down syndrome screening. How is the Down syndrome screening done? Has anyone done it before?Doctor's answer:
Tang screen is one of the essential pregnancy tests that must be implemented. It mainly evaluates the probability of fetal Down syndrome by testing the pregnant woman's blood to comprehensively assess the pregnant woman's age, weight, and gestational age. The best time for the examination is in the early pregnancy, 16-20 weeks. The screening results can be obtained within one week after blood draw. Down syndrome screening is an important part of prenatal examinations and an effective control measure for preventing the birth of Down syndrome children. It only requires a vein on the pregnant woman's upper limb, and blood draw is not very painful.
