While the doctor examined my pet, she explained that they are very thorough and tell you everything about the procedures and costs. She said my pet needed one test and I could bring my pet back if she needed another test. She told me the benefits of having both done at the same time. She said that adding the second test would give complete results. I accepted the fee of $240. I received a call from the doctor this afternoon with the test results. She said for $135, she recommends a third test. The third test would definitely produce complete results. So I just gave away $240 with no results! Third test? No thank you. I don't want to know the cost of the fourth test.
