One of the common tests for the Lyme disease has a very high false positive rate. My friend got scammed by a pseudo-doctor abusing this fact. Basically his father had huge health problems and they ran out of options so they went to that guy. It was obvious bullshit (diagnosing "parasites" with "electric resonanse", such stupid stuff, but they did it cause why not, it's not like it's going to make it worse). The guy also "tested" my friend and told him he has Lyme and should take this test in a normal medical clinic. My friend did and the result was positive. So he believed the guy for a while and took his "medicines" until he found out that test has 57% false positive rate :) After he took the other test and repeated it several times it turned out he doesn't have Lyme.
