Abstract
Paired blood and urine samples were obtained from patients between the sixth and 14th weeks of normal pregnancy. The levels of intact human chorionic gonadotropin (hCG), and of the free alpha and beta subunits, were measured by specific immunoassays. There was a close association between blood and urine levels of intact hCG and of the alpha subunit of hCG, but no relation between the levels of beta subunit in these sites. These findings suggest that the use of "beta subunit" assay may give discrepant results according to the fluid examined. By contrast, measurement of intact hCG appears to give similar results in blood and urine.This publication has 4 references indexed in Scilit:
