Use

The Transferrin, Serum test aids in diagnosing iron deficiency anemia and iron overload by measuring the level of transferrin in the patient's bloodstream, which is a protein that binds iron for transport in the blood. Transferrin levels can indicate the total iron binding capacity of the blood and are typically elevated in iron deficiency anemia or decreased in iron overload conditions.

Special Instructions

A fasting specimen is preferred for this test to ensure accuracy. After collection, allow the specimen to clot completely at room temperature before separating serum or plasma from cells. Ensure that the specimen is collected in a serum separator tube or plasma separator tube, with green (lithium heparin) also being acceptable.

Limitations

This test requires proper handling to ensure stability. Specimens collected in EDTA are unacceptable, as are hemolyzed specimens, which can affect the accuracy of the test results. It is important that serum or plasma be separated from cells ASAP or within 2 hours of collection to maintain the integrity and reliability of the results.
