Detailed explanation-1: -MCV/RBC values of less than 11.5 suggest thalassemia trait, while values greater than 13.5 suggest iron deficiency anemia. A much more definitive measurement of iron deficiency is to determine the ferritin level.
Detailed explanation-2: -The blood count in -thalassemia carriers shows low mean corpuscular volume (MCV) and low mean corpuscular hemoglobin (MCH). These parameters, which are easily measured by automated blood cell counters, can indicate suspicion of a carrier state.
Detailed explanation-3: -°-trait is usually marked by slight anemia, slightly reduced MCV and MCH, RBC microcytosis, hypochromia, and anisopoikilocytosis. During the neonatal period, Hb Bart’s can be detected in moderate amounts (3–8%). Some Heinz inclusion bodies (intracellular Hb precipitates) may also be detected.
