title: [Determination of estrone sulfate levels in the blood and urine of pigs].
abstract: The concentration of oestrone sulphate was determined in plasma as well as in urine to verify early pregnancy in pigs (within 24-29 days after mating). The threshold level in plasma was 0.70 ngr/ml. and in urine 50 ngr/ml. Accuracy was ninety-nine per cent in samples of plasma and ninety-two per cent in samples of urine respectively.
