Dual Marker Test is used to measure the presence of two hormones which are Beta Human Chorionic Gonadotropin (Beta hCG) and Pregnancy Associated Plasma Protein (PAPP-A) in blood. The hormone levels are used to estimate a risk for Down Syndrome and 2 other chromosome abnormalities together with the NT scan result.

Hi doctor, what is the normal range for women with gestational week 12-13. I took the test on 12 week 6 day and PAPP-A and Beta HCG value as 1.13 miu/ml and 17.8 ng/ml is this normal.
