Interpretation of pregnancy examination indicators

In this paper, the free /hCG β, hAFP, NTD risk and 2 1 trisomy risk in pregnancy test will be deeply interpreted to help expectant mothers better understand their physical condition and fetal health.

Free hCG β

During pregnancy, the level of free hCGβ changes constantly. At first, the concentration of free hCGβ increased rapidly, reached the peak in the eighth week of pregnancy, and then gradually decreased, and maintained at a certain level until about 18 weeks. The serum free hCGβ level of pregnant women with congenital stupid fetus is rigid, and the average MoM value is 2.3-2.4MoM.

hAFP

AFP is synthesized by yolk sac in early pregnancy 1-2 months, followed by fetal liver, and a small amount of AFP can also be synthesized in fetal digestive tract and enter fetal blood circulation. The serum AFP level of pregnant women with congenital stupid fetus is 70% of that of normal pregnant women, that is, the average MoM value is 0.7-0.8MoM.

NTD risk

Neural tube defect (NTD) is one of the most common congenital defects. China is a country with high incidence of neural tube defects, and the birth rate in the north is higher than that in the south. Neural tube defects include anencephaly, open spina bifida, closed spina bifida, encephalocele and hydrocephalus. Among all perinatal infants with birth defects, the incidence of neural tube defects is the highest, accounting for about 2 1% of the total number of defects. The average incidence rate of normal population is about 7‰.

2 1 trisomy risk

Your above test results are within the normal range, so it is low risk. I wish you a healthy baby.
