Abstract

The objective was to assess the association of fetal liver function tests in various (noninfectious) abnormal fetal conditions. Liver function tests and complete blood counts were evaluated in 72 consecutive fetal blood specimens obtained by cordocen- tesis. The indications for cordocentesis included: fetal malformation (24), red blood cell alloimmunization (23), possible fetal infection (17), oligohydramnios (5), and immunologic thrombocytopenic purpura (3). Statistical analysis included analysis of variance and linear regression analysis. Liver function tests including total protein, albumin, total bilirubin, alanine and aspartate aminotransferase were all within the range of previously published normal values. However, fetal y-gluta- myltransferase levels (mean ± SEM) were 157.1 ± 15.1 IU/1 (norm; 24.4 ± 1.2 IU/1; p < 0.001). There were no statistically significant differences in the γ-glutamyltransferase levels between the various groups of fetal abnormalities. Mean fetal y-glutamyltransferase levels in 8 normal fetuses were 106.2 ± 17.5 IU/1. In conclusion, fetal y-glutamyltransferase levels are significantly elevated in several abnormal fetal conditions.
