Blood component fractionation: manual versus automatic procedures

Area of Science:

• Blood banking and transfusion medicine
• Biomedical engineering
• Quality control in healthcare

Background:

• Recent introduction of quality system requirements for blood components impacts blood banks.
• Automated methods are crucial for meeting these new standards in blood component preparation.
• A novel automated device has been developed for blood fractionation.

Purpose of the Study:

• To evaluate the efficacy of a new automated blood fractionation device (Compomat G4) against manual methods.
• To assess the universality of the automated instrument across different blood bag systems.
• To determine the impact of automation on the quality of blood components.

Main Methods:

• 218 units of whole blood were processed using the Compomat G4 and Top/Top system.
• Blood was collected in various commercial blood bag systems (quadruple bags and bags with inline filters).
• Separate program protocols were developed for each bag type to optimize automated processing.

Main Results:

• The Compomat G4 demonstrated a statistically significant increase in hemoglobin in filtered red cell concentrates (RCC) compared to manual procedures (p<0.001).
• A statistically significant increase in platelets was observed in platelet concentrates (PCs) when using the automated versus manual procedure, irrespective of bag system.
• The automated procedure was found to be fast, user-friendly, and adaptable to different blood bag systems.

Conclusions:

• The Compomat G4 reliably produces acceptable blood components.
• Automated fractionation offers significant advantages in quality and efficiency over manual methods.
• This automated device is a viable solution for blood banks to meet evolving quality system requirements.
