Cobalt is a naturally occurring element which is considered a mineral. Small amounts of cobalt in the body contribute to normal cellular formation, but in high amounts it can be detrimental, causing skin and nerve damage. The most common method of exposure to cobalt is in the industrial setting and it can be inhaled, touched or ingested. This test measures the amount of cobalt in the blood plasma in order to diagnose toxicity. Deficiency in cobalt is rare since it is well supplemented in the diet and environment, therefore, this test is reserved for those exhibiting signs and symptoms of cobalt toxicity.
