M. Jacob et al., URINARY N-ACETYL-BETA-D-GLUCOSAMINIDASE IN THE PREDICTION OF PREECLAMPSIA AND PREGNANCY-INDUCED HYPERTENSION, Australian and New Zealand Journal of Obstetrics and Gynaecology, 33(4), 1993, pp. 395-397
Urinary N-acetyl-beta-D-glucosaminidase was estimated in 109 primigrav
idas and the level correlated with the subsequent development of preec
lampsia and pregnancy-induced hypertension in these women. The enzyme
value was significantly higher in those who developed preeclampsia. It
s sensitivity and specificity for the prediction of the disorder were
80% and 78% respectively. The positive predictive value was 21% while
the negative predictive value was 98%.
