Chromium and Cobalt, Whole Blood
Use
Detect metal ion accumulation caused by metal-on-metal (MoM) implants.
Special Instructions
Not provided.
Limitations
The reference interval and risk stratification are specific to patients with metal-on-metal orthopedic implants. The test does not combine chromium and cobalt levels for risk stratification but evaluates them individually. Metal ion tests provide adjunctive information for clinical evaluation but should not solely guide clinical decisions regarding revision surgery. Additional confirmatory or reflex tests may require extended turnaround time.
