Background: Functional iron deficiency (FID) is frequent in patients with Chronic Kidney Disease (CKD) and the parameters used in diagnosis are expensive and difficult to access. Beckman Coulter parameters are easy to calculate using mathematical methods, evidence demonstrates their use in detection of alterations in iron metabolism. Objective: To evaluate the clinical usefulness of Beckman Coulter parameters in the study of DHF in patients with CKD and type 2 diabetes (DM2). Materials and methods: Cross-sectional study. We reviewed 372 medical records and distributed them into groups: healthy subjects (n=212) and sick subjects (n=160). The diagnosis of DHF was made based on Ret-He <29 pg. Microcytic anemia factor (Maf®) and low-density hemoglobin (LHD%) were calculated using formulas. Diagnostic performance was evaluated through the area under the curve (AUC). Results: 81.25% of patients with CKD and DM2 had DHF. The analysis operator characteristic curve for Maf® in the diagnosis of DHF in CKD and DM2 indicated a sensitivity: 70.6% and a specificity: 68.5%, AUC of 0.71 (CI 95%: 0.63 - 0.78, p < 0.001) and a cut-off point of 10.83. On the other hand, the LHD% with a sensitivity: 23.5% and specificity: 98.6%, AUC: 0.60 (95% CI: 0.52-0.67, p=0.204) and a cut-off point of 1.91. Conclusions: Our findings demonstrate that Maf® has a good diagnostic performance and could be used as a screening test in patients with diabetic nephropathy for the diagnosis of DHF.
