Ferritin

Test Code

FER

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 Container

Plastic screw-cap vial

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: Daily; Report available: Next day

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.
