## Abstract In a large multi‐center trial involving prenatal screening for Smith–Lemli–Opitz syndrome (SLOS), we evaluated maternal urine and serum steroid analysis as a non‐invasive diagnostic alternative to amniotic fluid sterol analysis. Candidate steroid ratios included: 7‐dehydropregnanetriol/
The Smith-Lemli-Opitz syndrome (SLOS) is a common condition caused by deficiency of 7-dehydrocholesterol ⌬ 7 -reductase. The syndrome can usually be diagnosed by demonstrating markedly increased plasma concentrations of the cholesterol precursor, 7-dehydrocholesterol. We describe a simple and rapid
