RBC histogram: Useful diagnostic tool in evaluating anaemia

: Anaemia is a widespread public health problem, more common in developing countries. Red blood cell histogram is a vital part for evaluation and diagnosis of anaemia. Histogram can be a useful modality for arriving at the probable diagnosis of anaemia reporting in short span of time.: To observe various RBC Histogram on haematology Analyser in anaemia and analyse the usefulness of RBC Histogram to correlate with peripheral smear.: A prospective study was done in Department of Pathology of Secondary Care hospital from January 2024 to March 2024 on 300 anaemia patients. RBC Histogram were observed, analysed and correlated with peripheral smear. Out of total 300 patients, Most common anaemia is Microcytic Hypochromic (60%), Normocytic normochromic (21.33%), Dimorphic anaemia (12.33%) and macrocytic anaemia (6%). 95.5% microcytic hypochromic anaemia showed left shifted curve, 84.3% Normocytic normochromic anaemia showed normal curve, 88% macrocytic anaemia showed right shift curve. Considering the speed, reliability and less inter observer variation of the modern haematological analysers RBC histogram are important diagnostic tool for various types of anaemia and provide accurate morphological typing of anaemia in most cases hence presumptive report can be released based on RBC histogram.
