33 Diagnostic Tests Witness ® LH Luteinizing Hormone Diagnostic Test Ovassay ® Plus System Ovassay ® Plus System is the easiest and most accurate in- clinic, faecal flotation method for identifying gastrointestinal parasites. A clean faecal testing system with accuracy and safety in mind. The test can be used for detection of intestinal parasitic eggs in bovine, ovine, caprine, equine, canine or feline faeces. Zinc Sulfate flotation media is a solution which floats parasitic ova as well as Giardia cysts. Increased filter area for improved detection of low- level ova burdens. Client- friendly collecting procedure assures compliance with easy to follow sampling instructions and hands off collection. The device is 100% sealable and disposable. Overflow Reservoir to assure a non- spill test which will reduce exposure to potentially hazardous samples. . Units: 50 tests and zinc sulfate . Sample type: Feaces . Test Time: 10 minutes .

Since its inception, LH testing has a proven variety of uses in multiple species. During the canine estrus cycle, the LH surge may occur from days 3 to 28 ( average days 3 to 12) after observable signs of heat and lasts approximately 24 hours. Ovulation occurs 2 days after the LH surge. Ova then require an additional 2 to 3 days to mature into a stage that will support fertilization. The fertile period of the bitch falls between days 4 and 7 after the LH surge with the most fertile days being 5 and 6 ( the day of the LH surge is counted as Day 0). Determining the LH surge is perhaps the most critical factor in reproductive efficiency. . Determine Ovulation . Improve Procedure Scheduling . Increase Conception Rates . Predict Whelping Dates .
