Detecting cobalt toxicity
Monitoring metallic prosthetic implant wear
This test is not useful for assessment of vitamin B12 activity.
Because this test uses mass spectrometry detection, the radioactive form of cobalt, (60)Co, is not quantified.
Specimen collection procedures for cobalt require special specimen collection tubes, rigorous attention to ultraclean specimen collection and handling procedures, and analysis in an ultraclean facility. Unless all of these precautions are taken, elevated serum cobalt results may be an incidental and misleading finding.
<10.0 ng/mL (Metal-on-metal implant)
Reference values apply to all ages.
The reported unit of measurement for cobalt of ng/mL is equivalent to mcg/L.
