It is an anticoagulant for blood samples for CBC/FBCs, where the EDTA chelates the calcium present in the blood specimen, arresting the coagulation process and preserving blood cell morphology. Tubes containing EDTA are marked with lavender (purple) or pink tops. EDTA is also in tan top tubes for lead testing and can be used in royal blue top tubes for trace metal testing.EDTA is a slime dispersant, and has been found to be highly effective in reducing bacterial growth during implantation of intraocular lenses (IOLs). Alternative medicine
Some alternative practitioners believe EDTA acts as an antioxidant,  preventing free radicals from injuring blood vessel walls, therefore reducing atherosclerosis. These ideas are unsupported by scientific studies, and seem to contradict some currently accepted principles. The U.S. FDA has not approved it for the treatment of atherosclerosis. Cosmetics
In shampoos, cleaners, and other personal care products, EDTA salts are used as a sequestering agent to improve their stability in air. Laboratory applications
In the laboratory, EDTA is widely used for scavenging metal ions: In biochemistry and molecular biology, ion depletion is commonly used to deactivate metal-dependent enzymes, either as an assay for their reactivity or to suppress damage to DNA, proteins, and polysaccharides. EDTA also acts as a selective inhibitor against dNTP hydrolyzing enzymes (Taq polymerase, dUTPase, MutT), liver arginase and horseradish peroxidase independently of metal ion chelation. These findings urge the rethinking of the utilisation of EDTA as a biochemically inactive metal ion scavenger in enzymatic experiments.
Bazedoxifene/conjugated estrogens, sold under the brand name Duavee in the US and Duavive in the EU, is a fixed-dose combination medication for the treatment of menopause symptoms and postmenopausal osteoporosis. It contains the selective estrogen receptor modulator bazedoxifene and conjugated estrogens. It is taken by mouth. The combination was approved for medical use in the United States in October 2013, and in the European Union in December 2014. See also
