Higher Median Levels of Free β-hCG and PAPP-A in the First Trimester of Pregnancy in a Chinese Ethnic Group

12 Dec 2005

Abstract excerpt

OBJECTIVE: To study the effect of ethnic Chinese on the medians of free beta-hCG and PAPP-A in the first trimester of pregnancy. METHODS: The data of 943 women undergoing first trimester combined screening for fetal Down syndrome were analysed to derive the Chinese-specific medians. The calculated risk of Down syndrome based on these Chinese-specific medians was compared with that based on the original algorithm...
