Research output: Contribution to journalArticlepeer-review


Mean corpuscular volume (MCV) indicates the average volume of individual erthrocytes in Femtolitres (fL). The abnormality in MCV are clues to disease process: MCV values were calculated in all blood samples of consecutive admission in De-addiction centre AIIMS (Ward) with opioid dependence or alcohol dependence (from Oct'96 to june'97). Macrocytosis was found to be 75.2% in opioid dependent subjects as compared to 57.5% in alcohol dependent subjects. When macrocytosis was high. (> 130fL), mean haemoglobin contents were in the non anemic range. Macrocytosis if not investigated especially when anemia is absent or slight, it could lead to serious consequences.
