This document discusses using hematological profiles to identify thalassemia traits. It notes that beta-thalassemia carriers typically have microcytic and hypochromic blood with reduced MCV, MCH, and MCHC. However, hematological profiles are not effective at indicating HbE carriers, as these values are often normal. The document concludes that while hematological profiles can provide some clues about beta-thalassemia traits, premarital screening using high-performance liquid chromatography is essential to reliably identify carriers, prevent severe hemoglobinopathies in offspring, and address the high prevalence of traits in India.
