Alcance y aplicabilidad

This standard specifies the quality requirements for whole blood and blood components provided by general blood stations and for clinical transfusion. It is applicable to various blood products, including red blood cells, platelets, plasma, and granulocytes. Chapter 4 of this standard is mandatory, while the rest are recommended. It does not cover the labeling requirements of whole blood and blood components, which are addressed by other relevant national standards.

Requisitos técnicos

The standard outlines comprehensive quality control parameters for a wide array of blood products. It categorizes the requirements into blood safety testing and blood quality control. For safety, it mandates correct blood typing (ABO and RhD) and negative screening results for infectious disease markers, including HIV, HBV, HCV, and Syphilis. Compliance with these safety screening protocols is strictly enforced. For quality control, the standard specifies visual appearance criteria, requiring no abnormal coloration, hemolysis, clots, or bubbles, and intact blood bags with specific minimum tubing lengths. It also defines volume tolerances based on labeled volumes or source whole blood volumes (e.g., 200mL, 300mL, 400mL specifications). Hemoglobin content and hemolysis rate at the end of storage are critical parameters for red blood cell components. Platelet components must meet specific pH levels and platelet content thresholds, while plasma products are evaluated for plasma protein content and Factor VIII content. For leukocyte-reduced components, strict limits on residual leukocyte counts are established. Manufacturers must ensure all products pass sterility tests with no bacterial growth.

Métodos de ensayo

The standard references various testing methodologies to verify compliance. Key evaluations include visual inspection for appearance, volumetric measurement, and hematological analysis for hemoglobin and hematocrit. Sterility testing is conducted to ensure no bacterial growth. For safety testing, ELISA reagents and nucleic acid detection methods are utilized for infectious disease markers. Specific assays are also required for measuring residual substances like glycerol and methylene blue in treated blood components.
