Human chorionic somatomammotropin in normal pregnancy in an Asian population.
Serial Human Chorionic Somatomammotropin (HCS) levels were measured during the last 10 weeks of pregnancy in 57 patients (375 samples). There was a gradual rise from 5.6 microgram/ml at the 30th week to microgram/ml at the 40th week, with a plateau during the last 4 weeks of pregnancy. No correlation could be found of HCS levels with parity, maternal age, maternal height, maternal weight, foetal weight and foetal sex. A weak but significant relationship was found between HCS and plasma oestriol (r = 2.4, p less than 0.001).
