Ferritin
Test Code457
CPT Codes
82728
Preferred Specimen
1 mL serum collected in serum separator tube (SST)
Minimum Volume
0.5 mL
Instructions
Ensure that complete clot formation has taken place before centrifugation. Keep tubes stoppered and upright at all times. Centrifuge within 8 hours of collection, transfer serum to sterile, plastic, screw-capped vial(s).
Transport Temperature
Room temperature
Specimen Stability
Room temperature: 7 days
Refrigerated: 7 days
Frozen: 28 days
Reject Criteria (Eg, hemolysis? Lipemia? Thaw/Other?)
Gross hemolysis • Plasma
Methodology
Immunoassay (IA)
Setup Schedule
Set up: Mon-Sat; Report available: 1-2 days
Limitations
Liver dysfunction and other factors can cause a reduction in the clearance of serum ferritin resulting in an increase in serum ferritin levels. Ferritin is an acute phase reactant that may be elevated in a wide-range of inflammatory conditions and infections. Clinical studies suggest the sensitivity may be 35-48% and specificity of 75-78% to detect iron deficiency.
