FDA Status
This test was developed and its analytical performance characteristics have been determined by Quest Diagnostics. It has not been cleared or approved by the U.S. Food and Drug Administration. This assay has been validated pursuant to the CLIA regulations and is used for clinical purposes.
Setup Schedule
Set up: Tues-Sat (evening shifts); Report available: Same day after receipt at the performing laboratory. Add two (2) days for transport.
Reference Range
0.1-0.4 mcg/L
Clinical Significance
Cobalt is essential for humans only as an integral part
of Vitamin B12 (cobalamin). No other function for cobalt
in the human body is known. This provides for normal
reference ranges. Cobalt is found in metal alloys that
are very hard, have high melting points, and are
resistant to oxidation. Occupational exposure occurs
during the production and machining of these metal alloys
and has led to acute and chronic medical conditions.
