Patient's question:
I have been pregnant for several months and have been very particular about the timing of the baby's delivery. Before going to the hospital for prenatal care, I did a Down syndrome screening test. The test results show many data, and I would like to ask what the normal value of the first-trimester Down syndrome screening (UE3) is?Doctor's answer:
The reference values for Down screening results are: AFP: 0.7-2.5; HCG: 0.25-2.5; UE3: 0.5-2.0. However, if the test reagents are not many hospitals may have a slight tremor, so it is necessary to check the reference range behind. The critical values for other neural tube defect risks and 21 trisomy risks are: 1:280/370. The test results will be shown to the obstetrician and gynecologist of the hospital where you are tested to see if an amniocentesis is needed.
