the test is a urinanysis dip stick. some features on it do not give conclusive effidence of a problem. the specific gravity for one, is usually wrong on a dip stick. There is a different instrument that is more accurate that the vets use.
If you know what your doing and you know how these elements effect the body then i say go for it. Otherwise, leave it to the vet. your vet is not going to appreciate an owner calling them up saying they did an at home urinalysis and found that their dog has a high whatever when in fact they really don't and the owner did the test wrong. I dont think this test is for worrywort owners who freak at the slightest sign of something wrong.
If you are interested in getting the test, the most important things to look for are blood and protein. those are the two main things that indicate a UTI. |
