Unconjugated Estriol (u-E3)

PRODUCT NAME: AccuBind Unconjugated estriol (u-E3) 
INTENDED USE: The quantitative determination of Unconjugated estriol (u-E3) concentration in human serum or plasma by a Microplate Enzyme Immunoassay.
PRODUCT OVERVIEW: Unconjugated estriol in the serum of pregnant women originates almost exclusively from precursors in the fetus, via the placenta. uE3 may be used with AFP and hCG as a Triple Screen in pregnant women during their 3rd trimester to diagnose down-syndrome. Abnormally low levels of estriol in a pregnant woman may indicate a problem with the development in the child.
