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.
通过测量碱性磷酸酶(ALP)同工酶,可将囊状水瘤的液体与羊水区分开来。前者具有血清型碱性磷酸酶,主要由肝/骨/肾同工酶组成,几乎不含肠同工酶。孕中期羊水碱性磷酸酶约含80%的肠同工酶。
