Iron, Plasma or Serum
Also known as: FE
Use
This test aids in the diagnosis of iron deficiency anemia and iron overload. It measures the concentration of iron in the plasma or serum, which can be indicative of various health conditions related to iron imbalance.
Special Instructions
Patient preparation requires the collection of a plasma separator tube, serum separator tube, or green (lithium heparin) tube. It's crucial to separate serum or plasma from cells as soon as possible or within 2 hours of collection.
Limitations
Tests may be compromised if specimens are collected from patients receiving deferoxamine if taken within six hours before the test. Additionally, the presence of EDTA, sodium/fluoride, oxalate, sodium citrate, or gross hemolysis can cause specimen rejection due to interference with test results.
