-
Progesterone Stage Monitoring
Serial progesterone testing gives a quantitative measure of the bitch’s hormonal cycle. Rising progesterone ranges point out approaching ovulation, and the timing of the LH surge (which precedes ovulation) may be not directly inferred. If progesterone ranges aren’t monitored with enough frequency or if testing is initiated too late within the cycle, the estimated ovulation date could also be off by a number of days, resulting in an inaccurate projection.
-
Luteinizing Hormone (LH) Surge Detection
The luteinizing hormone surge is a direct indicator of impending ovulation. Detecting the LH surge permits for probably the most exact calculation of the anticipated whelping date. If the LH surge is missed solely, or if solely a single, late measurement is taken, the estimation of ovulation might be much less correct, impacting the reliability of the device.
