WITNESS™ LH Test Kit

Unsuccessful breedings often result from improper ovulating timing. The true fertile period is short (48-72 hours), and it is difficult to identify without the use of hormonal tests. The WITNESS™ LH Test has a proven variety of uses in multiple species. Use it to determine ovulation, improve procedure scheduling, increase conception rates, predict whelping dates and assess ovarian status. The WITNESS™ LH test provides an accurate, semi-quantitative measurement of canine and feline luteinizing hormone (LH). The test identifies the day of the LH surge, which actually triggers ovulation. Ovulation occurs two days after the LH surge. Recommended in instances where there are factors present that could adversely affect conception rates. These instances include chilled/extended semen breedings, frozen semen breedings, bitches with a history of infertility, stud dogs with low semen quality, and limited access to the stud dog. The test is simple to perform and rapidly provides information for the veterinary clinician. Includes test device and pipette. No returns on test kits.
