 View Topic Outline

Overview

  • Transferrin receptors are receptors on cell surfaces that internalise transferrin.
  • An increased soluble transferrin receptor level can aid in the diagnosis of iron deficiency if uncertain, particularly in differentiating iron deficiency from anaemia of chronic disease. Haemolysis will also caused a raised level.
  • This test is rarely used in clinical practice.
