Serum alpha-amylase activity was determined in 41 newborn infants with proven bacterial infections and compared to values obtained in 18 healthy control neonates. In the infected neonates serum alpha-amylase value, as determined by the blue starch method, was only 40% that of healthy controls; the mean value of 175.1 ± 64.9 IU/l for healthy neonates was significantly higher (p < 0.0010) than the value of 82.8 ± 44.4 IU/l for the infected neonates. Alpha-amylase levels did not correlate with severity of infections or mortality. The sensitivity and specificity of serum alpha-amylase level of 100 IU/l were 75.6 and 94.7%; the positive and negative predictive values were 91.2 and 84.4%, respectively.
