Overview
This article describes the preparation of double dose buffy coat platelet concentrates from whole blood donations using the INTERCEPT Blood System for pathogen inactivation. The quality of the final platelet units is evaluated over a storage period of seven days.
Key Study Components
Area of Science
- Hematology
- Blood transfusion
- Pathogen inactivation
Background
- Platelet transfusions are critical for patients with low platelet counts.
- Pathogen inactivation is essential to ensure the safety of blood products.
- The INTERCEPT Blood System is a method used to inactivate pathogens in platelet concentrates.
- Understanding the preparation process can improve clinical practices in blood centers.
Purpose of Study
- To demonstrate the preparation of pathogen-inactivated double-dose platelet concentrates.
- To evaluate the in vitro quality of the platelet units during storage.
- To provide a detailed procedural overview for blood center technicians.
Methods Used
- Whole blood is collected and centrifuged to separate components.
- Buffy coats are pooled and treated with platelet additive solution.
- The pooled buffy coats undergo further centrifugation to produce a platelet concentrate.
- The INTERCEPT Blood System is used for pathogen inactivation through UVA illumination.
Main Results
- The final double dose platelet concentrate meets specified volume and platelet dose requirements.
- In vitro quality assessments indicate acceptable levels of pH, glucose, and lactate over seven days.
- Pathogen inactivation is effectively achieved through the INTERCEPT process.
- The procedure yields two therapeutic doses from a single preparation.
Conclusions
- The described method is effective for producing safe platelet concentrates.
- Quality assessments confirm the viability of the platelet units over the storage period.
- This process can enhance the safety and availability of platelet transfusions.
What is the INTERCEPT Blood System?
The INTERCEPT Blood System is a method used to inactivate pathogens in blood products using UVA light.
How long can the platelet concentrates be stored?
The platelet concentrates can be stored for up to seven days while maintaining acceptable quality.
What are buffy coat platelet concentrates?
Buffy coat platelet concentrates are derived from the separation of blood components, specifically the layer containing platelets and white blood cells.
Why is pathogen inactivation important?
Pathogen inactivation is crucial to prevent the transmission of infectious diseases through blood transfusions.
What are the key quality indicators for platelet units?
Key quality indicators include pH, glucose, lactate levels, and platelet count.
How is the platelet concentrate prepared?
The preparation involves centrifugation, pooling of buffy coats, and treatment with the INTERCEPT system.
Can this method be used in all blood centers?
Yes, as long as the blood center has the necessary equipment and follows the specified protocols.
