Test Code LAB605 Iron Saturation, Plasma or Serum

Additional Codes

Test Name in EPIC EPIC Test Code Mnemonic
IRON SATURATION LAB605 FESTG

 

Useful For/Utility

Screening for iron deficiency.

Methodology

Iron: Ferene

Iron-Binding Capacity, Total (TIBC); Calculated from Transferrin: Immunoturbidimetric

Saturation: Calculation

Includes iron, TIBC, and iron saturation calculation.

Clinical Information

Percent saturation (100 x serum iron/TIBC) is usually normal or decreased in persons who are iron deficient, pregnant, or are taking oral contraceptive medications. Persons with chronic inflammatory processes, hemochromatosis, or malignancies generally display low transferrin.

Specimen Requirements

Submit only 1 of the following specimens:

 

Preferred:

Specimen Type: Plasma

Container/Tube: Light-green top (lithium heparin gel)

Specimen Volume: 1 mL

Specimen Minimum Volume: 0.5 mL

Collection Instructions:

1. Hemolyzed specimen is not acceptable.

2. Spin down, separate plasma from cells within 2 hours of draw.

3. If plunger filters are used, immediate removal of plasma is indicated unless an air gap can be created between the device and specimen.

Additional Information: Label specimen appropriately (plasma).

 

Alternate:

Specimen Type: Serum

Container/Tube: Red top and serum gel

Specimen Volume: 1 mL

Specimen Minimum Volume: 0.5 mL

Collection Instructions:

1. Hemolyzed specimen is not acceptable.

2. Spin down, separate serum from cells within 2 hours of draw.

3. If plunger filters are used, immediate removal of serum is indicated unless an air gap can be created between the device and specimen.

Additional Information: Label specimen appropriately (serum).
