PROGESTERONE TESTING

Progesterone (quantitative)
      A blood sample should be taken about day 7 post vulval bleeding. In most bitches the progesterone concentration will be <3 nmol/L indicating that ovulation has not occurred. If the progesterone level is above 6 nmol/L, ovulation has occurred and depending on the actual level we will advise when to sample again if required.

Interpretation
Progesterone <1.0 - 3.0 nmol/L Ovulation has not occurred, resample 3 -4 days
Progesterone >6 nmol/L Ovulation has occurred, resample again if required
Progesterone 16 - 20 nmol/L Mate within 33 - 57 hours
Progesterone 20 - 38 nmol/L Mate within 9 - 33 hours
Progesterone >38 nmol/L Mate within 9 hours
