Sorry, I still contend that almost all preventive tests are useless and unnecessary but do contribute to the Doctors and Hospital funds. Mostly due to prevent lawsuits.
I can understand your arguments but in my experience, they are and have been useless in both my parents and myself. Your case may be different but do not extend them to everyone.
The test 2.50, with the lab draw 27.50, this isn’t a huge money maker for anyone.
