Assessment of erythroid lineage

Clinical Information Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test

The transferrin receptor (CD71) is highly expressed on the surface of cells of the erythroid lineage and mediates the uptake of transferrin-iron complexes. Transferrin receptor expression levels are highest in early erythroid precursors through the intermediate normoblast phase, then expression decreases through the reticulocyte phase.

Reference Values Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.

This test is not an orderable test. Order 70012 / Pathology Consultation. The consultant will determine the need for special stains.

 

This request will be processed as a consultation. An interpretive report will be provided.
