Gadolinium is one of the most abundant ”rare-earth” elements but is never found as a free element in nature. Gadolinium has no known biological role in humans. Toxicity due to Gadolinium is rare due to its poor gastrointestinal absorption (it is suspected that very little Gadolinium is absorbed from the gastrointestinal tract (<0.05%), similar to other rare earth metals) and there is no information on the tissue distribution of Gadolinium. Most likely Gadolinium is excreted slowly through the fecal and urinary routes. If exposure to high enough doses and/or if absorption does occur, symptoms of acute parenteral toxicity may develop, including abdominal cramps, diarrhea, lethargy, muscular spasms, and even eventual death due to respiratory collapse. Gadolinium salts can cause irritation of the skin and eyes and are suspected to be possible carcinogens. As reported by Perazella (2009) Gadolinium-based contrast (GBC) agents have been linked on occasion with a rare systemic fibrosing condition called nephrogenic systemic fibrosis (NSF) and their use in patients with advanced kidney disease should be avoided. Gadolinium is often used in alloys, improving the workability and resistance of metals (e.g. chromium, iron). Other technical uses include the phosphors of color cathode-ray television tubes and in making magnets and electronic components such as recording heads for video recorders and in the manufacture of compact disks and computer memory. In medicine Gadolinium in MRI scan (magnetic resonance imaging) is used as a non-radioactive MRI contrast agent and has a half life in blood of about 90 minutes. It is also used in control rods for nuclear reactors and power plants, in making garnets for microwave applications. In vitro evidence suggests that EDTA may effectively bind to Gadolinium therefore EDTA for Gadolinium would be a good choice as a chelation agent.
Blood testing is not an accurate indicators of tissue levels of Gadolinium. You can do a provoked challenge, with a toxic metals urine collection which will show your total body load of Gadolinium, as well as other heavy metals. Hair Analysis will show gadolinium exposure over a longer period of time. You can order one of the following tests:
