Agreed.No reliable ones that I know of that I've heard of anyone using.
No matter where you are, you likely have some type of vet near you. Any vet will have the capability of performing a fecal test, even a normal cat/dog type of vet. They might not have the expertise to treat the infection, but you could call around and ask if any would be willing to take in a fecal sample and give you a count. From there, we can help you with what needs to be done treatment wise.
Or, if this is going to be an ongoing issue for you, you might look into investing in your own equipment to do your own fecal exams.
