Progesterone

LABOKLIN Service ID: 135

Measurement is performed to monitor luteal function.
Can be used during early pregnancy to confirm conception in cattle, horse, sheep and goat. However, as there are also increases in progesterone levels in the regular cycle, this difference is only diagnostically useful during the cycle-dependent decrease in progesterone. In horses and cattle, only samples which were taken on the 18^thand 19^th day after ovulation are useful and only prove that the animals are not in heat again at the expected time. Progesterone is not specific to pregnancy. The test cannot differentiate as to whether the corpus luteum has formed during the cycle or as a result of gestation.
Llama/Alpaca: Diagnosis of pregnancy from the 21st day of gestation onwards. In late pregnancy (10th/11th month), the determination of oestrone sulphate is also possible.
Female dog: Determination of the ovulation time, determination of the optimum time for mating, diagnosis of corpus luteum insufficiency (repeated determination).
