Agreed, Jeri. To me, it would seem perfectly reasonable to patent the test, but not the body part being tested. Although it is on a much smaller scale, it isn't really different from a company patenting blood so they can make money off of a blood test. I can't imagine what the US Patent Office was thinking when they let this through in the first place, but it was probably some junior clerk who was only concerned with all the blocks being filled out on the application form.
