Target’s vertical filter design allows for efficient washing of all unwanted blood components. As a result, the color produced is accurately related only to the progesterone in the serum sample.

Canine progesterone basics.



Canine progesterone basics


Predicting ovulation is done by accurately detecting the initial rise in progesterone (from C1 to C2). Ovulation usually occurs 2 days after the initial rise in progesterone (from C2 to C3). The most fertile time to breed is 2 to 4 days after ovulation (C4).

To time C-section or whelping, test progesterone starting 58 - 60 days after first breeding (average gestation is 63 days). A drop in progesterone to < 2 ng/mL (from C4 to dark C2 or C1) indicates whelping will occur within 24 - 36 hours.
