Patient's question:
Pregnant for over 3 months, I went to the hospital for a prenatal screening test a few days ago. I did a thorough check, but I won't know the results until later. I'd like to understand what the normal value range is for the Tissue Screening test.Doctor's answer:
The critical value for trisomy 21 is 1/2718. The critical value for trisomy 21 is 1/350. When the risk value for trisomy 21 is greater than 1/2718, or the risk value for trisomy 21 is greater than 1/350, high-risk populations need further testing and verification. If the screening risk value is relatively lower than 1/27, it proves that the fetus is healthy, and no further detailed examination is needed. The pregnant woman can rest assured and focus on caring for the fetus. During the process of nurturing the fetus, avoid eating any random or miscellaneous foods to prevent interfering with the fetus.
