La libération de l’hémoglobine (protéine pigmentée des globules rouges) a une influence importante sur l’aspect des culots globulaires et de leurs segments. L’hémolyse des culots globulaires entreposés est un processus normal qui s’accentue avec la durée de l’entreposage. Un certain niveau d’hémolyse est acceptable et prévisible. </span></span></span></p> <p class="MsoNoSpacing"><span><span><span>L’Association canadienne de normalisation (CSA) fixe la limite inacceptable d’hémolyse à ≥ 0,8 % de la masse de globules rouges dans 90 % des unités testées à la date de péremption. L’inspection visuelle de la couleur du liquide surnageant reste toutefois le seul moyen non destructif d’estimer l’hémolyse dans un culot globulaire. C’est une méthode très subjective, et il est difficile de définir une couleur limite pour l’acceptabilité d’une unité. La couleur du liquide surnageant permet d’estimer la concentration en hémoglobine. Toutefois, le pourcentage d’hémolyse d’un culot globulaire est également influencé par d’autres facteurs que la concentration en hémoglobine comme l’hématocrite ou l’hémoglobine totale. <span>Par exemple, une augmentation de l’hématocrite ou de l’hémoglobine totale entraînera un plus faible pourcentage d’hémolyse lorsque l’hémoglobine du liquide surnageant est maintenue à un niveau constant. La concentration en hémoglobine du liquide surnageant est donc l’un des seuls facteurs pouvant être pris en compte pour déterminer le pourcentage d’hémolyse d’un culot globulaire.</span></span></span></span></p> <figure role="group" class="caption caption-drupal-media align-center"><div> <div class="field field--name-field-media-image field--type-image field--label-visually_hidden"> <div class="field__label visually-hidden">Image</div> <div class="field__item"> <img loading="lazy" class="img-fluid" src="//professionaleducation.blood.ca/sites/default/files/2024-01/Fig1_Hemolysis%20calculation.jpg" width="515" height="147" alt="Percent hemolysis equals [(100 - hematocrit) x supernatant hemoglobin (g/L)] divided by total hemoglobin (g/L)" typeof="foaf:Image" /></div> </div> </div> <figcaption><strong>Figure 1</strong>.
