What does the Cobalt (Blood) test measure?

Q: Which tests measure Cobalt (Blood)?

Cobalt (Blood) is measured in 1 test on BiomarkersLabs.com, including Comprehensive Blood Elements.

Cobalt (Blood) (Co) is a clinical biomarker used in heavy-metals-toxicology assessment. Cobalt is the central metal ion in vitamin B12 (cobalamin) and is thus indirectly essential, but free ionic cobalt has no known independent metabolic role in humans. It is measured in 1 laboratory test on BiomarkersLabs.com.

Reference Range: Background typically <1 µg/L; prosthetic implants can raise blood cobalt into the range of toxicity.

What is Cobalt (Blood)?

Cobalt is the central metal ion in vitamin B12 (cobalamin) and is thus indirectly essential, but free ionic cobalt has no known independent metabolic role in humans. Elevated blood cobalt from occupational exposure or metal-on-metal hip prostheses can cause cardiomyopathy, hypothyroidism, polycythaemia, and neurological damage.

Why is Cobalt (Blood) measured?

Blood cobalt is ordered primarily to monitor patients with metal-on-metal orthopaedic implants and in occupational medicine. Sustained elevations are associated with systemic toxicity, and high cobalt levels after arthroplasty may prompt revision surgery.
