Even using the most advanced equipment and high-speed centrifuges, fecal tests are only about 80% accurate, which is why a lot of veterinarians request multiple stool tests several weeks apart on puppies and kittens even after they have had one test come back negative.
Dispensing dewormer willy-nilly can end up being costly too, if you are worming for things that the dog doesn't actually have and then need to pursue additional treatment down the road when that does not work-- it's more responsible to know what you're targeting before handing out medication, especially since some parasites that are common in puppies do not respond at all to broad spectrum dewormers. |
When you take in a sample with worms (segments) in it....It is the incompetence of the lab and the vet. My vet in Texas performed his own fecal exams and could identify and prescribe as necessary on the spot. Especially if you're taking in samples over a 2 week period. I do know that one vet was very upset with the lab.....Especially when a negative result was called to me. What would have happened had a pet owner not versed and more knowledgable and would have accepted their diagnosis....
I would never administer de-worming meds unless checked by a vet.
