I m not saying for one minute I dont believe, in fact I thank you for telling me this, its something I'll have to check up on. Why the heck did they use that then when they were suppose to be testing for Mercury, cos they had confirmed that before with fecal metal test? I am so confused. Please tell me anything more you know about this. Its really important to me as I have to speak to someone at the hospital. Did you find this out anywhere I could check. Thanks again love Tracy xxx You people are great... I am feeling extremely ill today, In fact drop dead ill. I truly need allthe advice and help I can get. Bless you Tracy
