The Access Unconjugated Estriol assay is a paramagnetic particle, chemiluminescent immunoassay for the quantitative determination of unconjugated estriol levels in human serum using the Access Immunoassay Systems.
A collection of reagents and other associated materials intended to be used for the qualitative and/or quantitative detection of free estriol (oestriol) in a clinical specimen, using a chemiluminescent immunoassay method. It is typically measured in maternal blood or urine as a marker of foetal health, gestational age, or fetoplacental distress typically in pregnancies complicated by diabetes, hypertension, or prolonged gestation.
