Cobalt, Blood

Overview:

Cobalt is an essential trace element in very small amounts, as part of vitamin B12, but larger exposures can cause problems. The most common reason for testing is a metal-on-metal joint replacement, particularly a hip, where friction between components can release cobalt and chromium into the surrounding tissue and bloodstream. Raised levels in that setting can accompany local tissue reactions and, at higher concentrations, effects on the heart, thyroid and nervous system. Cobalt is also measured in some industrial exposures. Results are interpreted alongside chromium levels, imaging and symptoms rather than on their own.
