Molybdenum, Serum or Plasma

Molybdenum is an essential trace mineral that functions as a cofactor for enzymes involved in metabolizing sulfur-containing amino acids and certain waste products like sulfites and urates. Deficiency is rare and usually linked to genetic disorders or long-term parenteral nutrition. This test measures molybdenum levels in serum or plasma to evaluate for potential toxicity or, less commonly, deficiency.
