General Information

Cobalt is found in metal alloys that are very hard, have high melting points and are resistant to oxidation. Occupational exposure occurs during production and machining of these metal alloys and has led to interstitial lung disease. Cardiomyopathy and renal failure are symptomatic of acute cobalt exposure. The most effective means of identifying individuals with excessive cobalt exposure is through quantification of Urinary Cobalt.

Patient Preparation

Cobalt clears from body within 3 days of exposure ceasing. Check patient still exposed at time of collection

Reference Range
