Serum soluble transferrin receptor in the diagnosis of iron deficiency in chronic liver disease.
Fifty-one consecutive patients with chronic liver disease (CLD) underwent investigations of their iron status (full blood count, serum iron [Fe], total iron binding capacity [TIBC], transferrin saturation [TS], serum ferritin and serum soluble transferrin receptor [sTfR] level). Twenty-six patients were anaemic; 12 patients had iron deficiency, and 10 had iron deficiency anaemia (IDA). The median (range) sTfR in the IDA patients was 16.6 (11.2-24.8) mg/l. compared with 6.6 mg/l (11.2-24.8) in the 16 patients with anaemia due to other causes (P = 0.01). The sensitivity of sTfR for diagnosing iron deficiency in CLD was 91.6% (100% if only anaemic patients are included) and the specificity was 84.6%. Patients with haemolysis and recent blood loss may have falsely elevated sTfR levels. The results suggest that the sTfR is as useful as serum ferritin in identifying a potentially treatable cause of anaemia in CLD.
