Two recent publications by Cuckle et al., and one each by Canick et al. and Kellner et al., describe the use of urine beta-core fragment measurements as a screening test for Down syndrome pregnancies. Median levels of over 5.4 MOM were reported for cases of Down syndrome, with an over 72 per cent de
Variable results have been reported using urine -core fragment as a marker for fetal Down syndrome. Initial studies by Cuckle et al. (1994) and Canick et al. (1995) indicated that -core fragment was an outstanding marker, detecting >80 per cent of Down syndrome cases. Since these reports, widely var
## Recent articles by Cuckle et al., Canick et al., and Isozaki et al. have evaluated urine -core fragment as a screening test for Down syndrome in second-trimester pregnancies. They found over four-fold elevation of -core fragment levels in Down syndrome pregnancies, and between 62 and 88 per ce
Several studies have shown that second-trimester maternal urine -core human chorionic gonadotrophin (hCG) levels are raised on average in Down syndrome pregnancies. However, in all but one, testing was retrospective after extended sample storage and so we carried out a large international multicentr
