Tang sieve results were taken today, which is high risk. So, what do you think of the results of Down’s screening?
determines the risk of Tang Screening, and mainly depends on three indicators:
1. Alpha-fetoprotein (AFP) Alpha-fetoprotein is a specific globulin of the fetus, and the normal value should be greater than 2.5MoM. For pregnant women who are pregnant with congenital fetuses, the serum alpha-fetoprotein level is 70% of that of normal pregnant women. The lower the test value, the higher the chance of the fetus suffering from Down's disease. MoM is a multiple of the median value, which refers to the detection results of serum markers in pregnant women in prenatal screening are the median serum marker concentrations of normal pregnant women at this gestational week.
2. Free-β subunit - chorionic gonadohormone (Free hCGβ) Pregnant women with congenital foetus have ankylosing levels of chorionic gonadohormone in serum, and the higher the index, the higher the chance of the fetus suffering from Down's disease.
3. Free estriol (uE3) Free estriol is the main estrogen produced by the fetal placenta. Pregnant women with congenital foetus have a decrease in the uE3 value in the blood.
Blood test screening value: If the blood test screening value is greater than 1/270 of the international standard, pregnant women are at high risk. The high-risk group just says that the fetus is Down's child , and the low-risk group may also give birth to the Down's child. 
Of course, it doesn’t matter if you don’t understand what you said above. The Tang Screen Report is very clear, whether it is high or low risk is clear at a glance.
You can certainly feel at ease if you have low risks, while high risks require further prenatal diagnosis, such as amniotic fluid puncture . I made an appointment for amniotic fluid puncture, and I hope there will be no problem with the diagnosis by then!
