Abstract
The aim of this study was to determine the haematological quality of stored blood intended for transfusion. The study was prospective and experimental, based on the evaluation of the haematological quality of stored blood intended for transfusion, and took place between 11 October and 11 January 2024. We collected ten bags of blood from volunteer donors, following a physical examination of those who met the required conditions. A total of 10 250 mL blood bags were collected in Malueka, one of the Ngaliema clinic's blood collection sites. The haemogram parameters and the erythrocyte morphology study were determined before storage and these results were used as references. Each unit of blood was then divided into 3 for storage in three different blood banks. An interval of 7 days was observed for each series of haemogram analysis. Erythrocyte morphology was performed up to day 35 to assess the quality of the blood stored in the three locations. The variances of each series of 6 determinations were used to assess blood quality quantitatively. The Snedecor File test was applied to compare the different variances recorded in each blood bank.
