I really wish I knew. I don't have any ceramic dishes and, as far as I know, I have no other known exposure to lead. I don't work around it and I don't smoke etc. I work in an office behind a computer.
As some of you have suggested, I do believe that I will go for a retest. I know it is a thin hope but it sure would be nice if that first one was just wrong.
It was an actually blood draw, not a finger prick so the chances that it was wrong are very small.
This really has me confused and more than a little upset. I don't believe that the activities I have done could possibly be the entire story. My home was built in the 90s so I doubt it is a factor. I would worry more about my home and land but the rest of my family tests at near zero so that doesn't make a lot of sense either.
The sad truth is that I am not really worried about my health so much as the fact that, since I don't know what I did to get so high, I am uncertain whether I should wait the 3 months without even touching my guns stuff or whether I should just be more diligent and keep going. I have a lot of time, money and emotional investment in the hobby.
I do have to question whether some of you guys who say you have never had a problem have actually been tested. I was talking to some shooting buddies that were saying, basically, the same thing, that they have been shooting, reloading and casting for years without having a problem. When I really pinned them down on it, not a one of them had actually ever had a blood test done. If you haven't, you might want to think about it to be sure.
