Your lipids panel, about $60-75.00 will check for sugar, cholesterol, stuff like that. It checks a bunch of other stuff also, like ph, T-Cells, lymphocytes, it'll give an indication of abnormal levels of things.

but it doesn;t check for heavy metals, that is a separate test and rather expensive, usually over $1000 unless you only do a fecal/urine test for metals.

My stomach felt very weak from mercury posioning, a series of colonics seems to have that under control. the chest heaviness seems to be a common symptom of many people with mercury poisoning here but it could be something else I suppose. find an integrative med Dr to run the metal tests maybe, IV EDTA helped my weird chest symptoms a lot. Not sure heaviness is how I would describe it though, more like major congestion w/some sharp pains.

Kind of gross but if you get a lot of flem coming up, do not swallow it. your lungs are always filtering/detoxifying, spit instead so that your kidneys do not have to deal with whatever it is.
