Overview of High Fluorescence Ratio (HFR), Middle Fluorescence Ratio (MFR), Mean Cell Volume (MCV), and Mean Cell Hemoglobin (MCH) in Patients with Hemoglobin Levels Below 8

Key Points

Patients with severe anemia showed variations in high and normal fluorescence ratios, indicating diverse anemia types.
About 30% of patients had high fluorescence ratios with normal mean cell volume and mean cell hemoglobin metrics.
Variations in anemia types reflected possible different causes, with most patients showing a good regenerative response.
The study identified correlations between fluorescence ratios and red blood cell metrics like MCV and MCH in severe cases.

Abstract

Background 6 patients (20%) had normal HFR and MFR with normal MCV and MCH; 5 patients (17%) had high HFR and MFR with low MCV and MCH; 3 patients (10%) had high HFR, normal MFR, and low MCV and MCH; 2 patients (7%) had high HFR and MFR with normal MCV and low MCH; 2 patients (7%) had normal HFR and MFR with low MCV and normal MCH; 1 patient (3%) had normal HFR and MFR with low MCV and MCH; 1 patient (3%) had normal HFR, high MFR, with low MCV and normal MCH; and 1 patient (3%) had normal HFR, low MFR, and normal MCV and MCH. Conclusion: This study indicates that most patients with severe anemia (Hb < 8) showed a relatively good regenerative response (as indicated by high HFR and MFR), although variations in anemia types were also observed based on MCV and MCH values, reflecting possible different causes and classifications of anemia.
