There are always doubts, but sometimes that box is smarter than we are.
Last test on my Dad Lupus showed up, pretty high value too. I ignored it; he is 87 how could something like that be missed? Maybe the machine got a response for something else in that frequency range and just showed the wrong thing…
Today I went to visit and he showed me a rash on his thigh that sure looks like a Lupus rash.
Will run a Lupus script on him tomorrow (F125) and see if that helps.
