The results of the test showed that the water which is sent to over 7 million residents had average levels of 0.23 ppb of the toxic metal. Symptoms associated with chromium toxicity vary based upon route of exposure and dose and may include dermatitis, impairment of pulmonary function, gastroenteritis, hepatic necrosis, bleeding, and acute tubular necrosis. (1) Health Hazard Information Acute Effects: Chromium VI Prosthetic devices produced by Depuy Company, Dow Corning, Howmedica, LCS, PCA, Osteonics, Richards Company, Tricon, and Whiteside typically are made of chromium, cobalt, and molybdenum. EMSL is a leader in Hexavalent Chromium Laboratory Testing Services. Hexavalent chromium is a form of the metallic element . J Bone Joint Surg Am 2010;92:1-5. A modest increase (0.3-0.6 ng/mL) in serum Cr concentration is likely to be associated with a prosthetic device in good condition. The systematic risk stratification includes recommendations for multiple modes of failure and stratifies patient risk groups based on a thorough clinical history, a detailed physical examination, radiographic tests, and laboratory tests, including measurement of metal ions (chromium and cobalt). Q. Chromium metal is added to alloy steel to increase hardenability and corrosion resistance. Cr(+6), a known carcinogen, is immediately converted to Cr(+3) upon exposure to biological tissues. Chromium has a wide range of industrial uses because of its magnetic properties, its hardness and its usefulness as an ingredient to reduce corrosion in steel. Testing for Hexavalent Chromium is made easy by simply placing Home-Health-Chemistry's test strips in a water-based solution  and comparing the color change to the provided reference card. Serum chromium level normally is less than or equal to 1.4 micrograms/liter (µg/L) or 26.92 nanomoles/L (nmol/L). According to the study, the chromium industry did not notify OSHA of a study it conducted in 2002 on the health effects of lower exposures to hexavalent chromium. You will receive 5 Chromium VI test strips and an instructional card describing how to carry out the screening procedure, with a concentration color chart ranging from 0.5 to 100 mg/liter (0 - 100 ppm). The long-term consequences of exposure to these compounds in drinking water sources were uncertain. A paper given by Susan R.

It is extremely useful for those working in industrial environments where chromium is present. Results greater than the flagged value indicate clinically significant exposure to chromium (Cr) (see Cautions about specimen collection). The Chromium RBC Test is also available. Vincent JB: Elucidating a biological role for chromium at a molecular level. Serum concentrations above 1 ng/mL in a patient with a Cr-based implant suggest significant prosthesis wear. ATS can also analyze for hexavalent chromium specifically using either the spot-test procedure or the boiling water extraction/UV-VIS procedure outlined in IEC 62321. community for the purpose of testing their blood for chromium. Specimens collected using an anticoagulant are unacceptable; trace amounts of chromium are present in anticoagulants used in evacuated collection tubes. You'll be able to check drinking water as well as solid samples by mixing or dissolving them into water. Serum Cr concentrations are likely to be increased above the reference range in patients with metallic joint prosthesis. Talk to your provider about the meaning of your specific test result. Commercial evacuated blood collection tubes not designed for trace-metal specimen collection yield serum containing 2.0 ng/mL to 5.0 ng/mL chromium derived from the collection tube. Reports of increased serum chromium could be due to external contamination. The test kit contains enough reagents to perform approximately 100 tests. chromium.
