Hematological Indices for Differential Diagnosis of Beta Thalassemia Trait and Iron Deficiency Anemia
Table 2
Different RBC indices and mathematical formulas used to differentiate between β-TT and IDA.
| Hematological index | Formula |
| Mentzer index (MI) (1973) | MCV/RBC | RDWI (1987) | MCV × RDW/RBC | Shine and Lal (S and L) (1977) | MCV × MCV × MCH/100 | Srivastava (1973) | MCH/RBC | Green and King (G and K) (1989) | MCV × MCV × RDW/Hb × 100 | Sirdah (2007) | MCV − RBC − (3 × Hb) | Ehsani (2005) | MCV − (10 × RBC) | England and Fraser (E and F) (1973) | MCV − (5 × Hb) − RBC − 3.4 | Ricerca (1987) | RDW/RBC | MDHL (1999) | (MCH/MCV) × RBC | MCHD (1999) | MCH/MCV |

MDHL index: mean density of Hb/liter of blood; MCHD index: mean cell Hb density.
