Objetive: Multi-parameter studies combining serum Transferrin Receptor (sTfR) with Ferritin, hemoglobin,transferrin saturation percentage for an assessment of iron status. Materials and Methods.Subjects:Healthy Adults (HA)(n=51) and Iron-Deficient Anemic Patients (IDAP) (n=50). sTfR and Ferritin weremeasured by ELISA. Results: Mean confidence interval IC95(μ) showed that the mean value for sTfRwas 15.5-18.1 nmol/L (95% probability) in HA group. In IDAP both the sTfR mv and range (66.3 nmol/L, 16.1-148.4 nmol/L, (α) 0.05), and the sTfR/F Index (75.8) were greater than in HA (5% significancelevel). TfR/Hb (p<0.001), 71% (r2), and Ferritin/Hb (p<0.001), 70 % (r2), showed that for Hb <120g/L, sTfR is more sensitive than Ferritin. sTfR/Ferritin (p<0.001), 72% (r2) showed significant sTfRincreases for ferritins <12μg/L. Conclusion: Our studies confirm that the sTfR detects iron-sensitivechanges with a diagnostic accuracy. The combined use of sTfR and conventional parameters allows foreasier iron status assessment.Downloads
