I suggest that you use a colonoscopy prep that uses polyethylene glycol (PEG) with electrolytes rather than sodium, magnesium and potassium sulfate. PEG with electrolytes is much safer than the sulfate. The thallium and the Cardiolite will not result in any kidney damage. Propofol does not cause any concerns for kidney disease. I suggest that you discuss your concerns with the physician who ordered these tests.
