Patient's question:
What is the Tandem Screen? Who should undergo this test?Doctor's answer:
Hello, TPS is the abbreviation for Triple Screen, which is a method of detecting the concentration of alpha-fetoprotein and human chorionic gonadotropin in maternal serum by drawing pregnant women's blood, and calculating the risk coefficient of giving birth to a child with Down syndrome by combining the pregnant woman's due date, age, weight, and gestational age at the time of blood collection. The best time for screening is between 15 and 20 weeks of pregnancy. Generally, pregnant women can receive screening results within one week after blood draw. If the result is high-risk, there is no need to panic, as further amniocentesis and fetal chromosome examination are required to confirm the diagnosis.
