Distinguishing hygroma and amniotic fluid.
Fluid from cystic hygromata can be distinguished from amniotic fluid by measurement of alkaline phosphatase (ALP) isoenzymes. The former has a serum-type ALP, made up largely of the liver/bone/kidney isoenzyme and virtually no intestinal isoenzyme. Second trimester amniotic fluid ALP contains approximately 80 per cent intestinal isoenzyme.
