Had you eaten fish recently when you took the test? I'm not sure, but I think it is unusual to turn up high in the blood as it settles into tissues pretty quickly. Since it did come back high I would definitely look at mercury as a possible source of your symptoms. Testing for mercury does appear to be tricky. I had a hair test several years ago and the mercury came up very low so we just stuck with treating candida. I stayed on my diet very strictly but could never get rid of the candida. Even a piece of fruit would trigger symptoms. Last summer, another doctor really felt I had symptoms of mercury, so he gave me a challenge test which was a urine test collected after taking oral DMPS (a chelator). My mercury came back very elevated. I got my last two fillings out (most were replaced years ago) and that triggered severe symptoms (that's another way to figure out if your symptoms are mercury related). Many of my symptoms are gone - I still struggle with candida but it is very mild compared to what it used to be and I am still detoxifying. Do you have other symptoms - gastrointestinal, ear ringing, sinus infections, muscle twitching, fatigue, etc.? I would not think a hematologist will be of much help - you need someone who specializes in toxicity - and a good dentist to get those fillings out of your mouth safely. Don't worry too much about your family - I have been through that. As you continue to educate yourself on health and get well, some of them will be coming to you for advice.
