Cobalt, Serum/Plasma
Test Summary
Cobalt is essential for humans only as an integral part of Vitamin B12 (cobalamin). No other function for cobalt in the human body is known. This provides for normal reference ranges. Cobalt is found in metal alloys that are very hard, have high melting points, and are resistant to oxidation. Occupational exposure occurs during the production and machining of these metal alloys and has led to acute and chronic medical conditions.
