Determination of Medians of Biochemical Serum Markers in First Trimester of Healthy Pregnant Women in Tertiary Care Setup.
Pak Armed Forces Med J Jan ;72(2):668-71.

Objective: To determine medians of pregnancy-associated plasma protein-A (PAPP-A) and free β subunit of Human Chorionic Gonadotropin (hCG-β) in the first trimester of healthy pregnant women visiting tertiary care hospital. Study Design: Cross-sectional study. Place and Duration of Study: Department of Chemical Pathology and Endocrinology, Armed Forces Institute of Pathology (AFIP) from May 2018 to May 2019. Methodology: Healthy pregnant women with a singleton pregnancy reported for an antenatal checkup in Obstetric OPD, Pak Emirates Military Hospital (PEMH) and Combined Military Hospital (CMH) Rawalpindi were included in the study. PAPP-A level was determined by enzyme-linked immunosorbent assay (ELISA) method using PR 4100 Microplate Reader®, and serum hCG-β were analysed on random access IMMULITE 2000®. Results: A total of 135 pregnant women were enrolled in the current study. The mean age of subjects was 27.66 ± 4.24 years, mean maternal weight was 59.91 ± 8.87 kgs and mean gestational age was 10.37 ± 1.16 weeks. Median value of PAPP-A was 1289.43 mIU/L (range: 510.8-5965.99) and hCGβ was 120985 mIU/ml (range: 23592-290000). Conclusion: Median values of PAPP-A and HCGβ can be used to calculate (Multiple of Medians) MoM during the first trimester in tertiary care setup.
