I would urge you to do some more research. Over testing is well known to cause higher rates of unnecessary medical procedures. There are many ways it can break down. For instance, the test may false positive consistently if an individual has some other factor such as mediation, virus, or bacteria that confound the test. Tests are also only validated under certain criteria. For instance if the clinical trial only tested people who presented with certain symptoms, the efficacy of the test may be completely different on the general public.
