[Secretion of progesterone and placental lactogen during physiological pregnancy]

The authors present correlation results of the information content of the determination of progesterone as compared to those of placental lactogen. Placental lactogen was determined by means of the radioimmunoassay kit "CEA IRE SORIN", whereas progesterone by means of the Soviet kit "STERON-II-125I" produced at the Institute of Organic Chemistry, AS BSSR. It has been established that the time course of the content of placental lactogen and progesterone in the blood in uncomplicated pregnancy is of positive nature and changes simultaneously. There is every reason for a wide use of progesterone determination during complicated gestation which is as informative as placental lactogen determination but more accessible in clinical practice.
