A radioimmunoassay procedure for human chorionic somatomammotrophin in indiluted plasma has been developed in which the incubation lasts only five minutes rather than one half hour to four days in the previously described methods. The values obtained had excellent correlation (p less than or equal to 0,001) with those obtained by a two-hours technique. The intra-assay and inter-assay coefficients of variation are respectively 7 percent and 11 percent. Twenty women at term showed human chorionic somatomammotrophin values of 7.5 +/- 2.5 mug/ml plasma (mean +/- SD).
