| KristaS, Debbie- I was told by a vet that the "quick" test, reading a blood smear under the microscope in the office, will only let you know if the immature HW (microfilae?) is circulating in the bloodstream. The other test (which some vet offices have the equipment to test in-house) will test for mauture HW. The "quick" smear misses adult HW entirely. I think it's OK for dogs who have consistently been on preventative, though. |
