[Comparative studies on 2 radioimmunoassay technics for the rapid determination of human chorionic somatomammotropin (HCS) in normal early pregnancies].
To measure HCS concentrations in serum in early pregnancies, 2 commercially available kits (Pharmacia, Frankfurt, and Amersham-Buchler, Braunschweig) were used. When comparing them, we found that they were nearly of the same quality and equally suited for the measurement of HCS in early pregnancy. We ourselves should prefer to use the Amersham-Buchler kit, because it uses 2 standard curves, covering 2 ranges and thus avoiding to tilute the patients' sera, which decreases the possible pipetting errors and increases the accuracy of the determinations.
