Plasma Color in Blood Donors : A Review article

Abstract

Plasma is the liquid component of blood. Blood collected from donors undergoes processing using a blood component centrifuge, which separates plasma from other blood components, including red blood cells, white blood cells, and platelets. Plasma is commonly transfused to patients with various conditions, such as severe burns with shock, severe liver disease, or multiple clotting factor deficiencies. After centrifugation, plasma typically appears yellow, ranging from light yellow to dark yellow. However, in some cases, plasma may exhibit abnormal colors, including red, green, orange, icteric yellow, and cloudy white. Variations in plasma color can result from multiple factors, including physiological conditions, dietary intake, medication use, and procedural factors during blood component preparation. This review article examines the underlying causes of plasma discoloration. Understanding these causes enables blood bank personnel to distinguish abnormal plasma from normal plasma, reducing unnecessary plasma discards and increasing the availability of plasma for patient care.Plasma is the liquid component of blood.
