I have a friend who is 31 years old. her blood levels are off like platelet, c, mch, mchc, rdw,wbc,hemoglobin,hemocrat. she started with black tongue ad black spots on her body. I read that most of these are caused by ITP and that is what her dr is suggesting. I read though that lead posioning can cause some of the levels to be off. we live in a country with no lead regulations. what i am wondering is could lead posioning cause ITP?
