I am begging people to understand that almost every test on the planet has something called "false positives," which means a risk that a result of the test is WRONG. A WRONG result can lead to necessary fear, worry, and at worst, unnecessary INVASIVE procedures or even unnecessary surgery. The chance of someone getting a false positive goes down when the person is at a higher risk of having an actual problem (ie. A specific SYMPTOM). This is called a higher "pretest probability." This is why doctors don't recommend everyone get every test all the time.
