Molybdenum, Serum
Use
Molybdenum is an essential trace element found in the daily diet. It is a cofactor for enzymes important in nitrogen metabolism. Molybdenum deficiency is rare due to its wide distribution in the environment but can occur with parenteral nutrition deficiency. Monitoring molybdenum levels is crucial for patients receiving parenteral nutrition, have metallic prosthetic implants, or suffer from molybdenum cofactor deficiency. Elevated levels may indicate molybdenum toxicity or increased metallic prosthesis wear.
Special Instructions
High concentrations of gadolinium and iodine can interfere with the test. Avoid collecting specimens within 96 hours of administering gadolinium- or iodine-containing contrast media.
Limitations
This test has not been cleared or approved by the FDA and is not intended to diagnose, treat, cure, or prevent any disease. Increased serum molybdenum levels may occur in liver diseases and are not specific to prosthesis wear. Interpret results with clinical correlation.
