Review Considerations for Whole Blood and Red Blood Cells
• Validation– No recommendations in LR guidance– establish documented evidence which provides a high
degree of assurance that a specific process will consistently produce a product meeting its pre-determined specifications and quality characteristics
• Monthly QC – 1% of collections for each product type, selected at
random; if less than 400 per month, then 4 of each product type
– 95% meet product standards
![Page 19: Leukocyte-Reduced Blood Components Lore Fields MT(ASCP)SBB Consumer Safety Officer, DBA, OBRR, CBER September 16, 2009.](https://reader035.fdocuments.us/reader035/viewer/2022062719/56649eef5503460f94bff613/html5/thumbnails/19.jpg)

Review Considerations for Whole Blood and Red Blood Cells
Whole Blood, Leukocytes Reduced and Red Blood Cells, Leukocytes Reduced should be prepared by a method known to:– leave a residual leukocyte count of less than 5.0 x
10e6 per container and – retain a minimum of 85% of the original component
![Page 20: Leukocyte-Reduced Blood Components Lore Fields MT(ASCP)SBB Consumer Safety Officer, DBA, OBRR, CBER September 16, 2009.](https://reader035.fdocuments.us/reader035/viewer/2022062719/56649eef5503460f94bff613/html5/thumbnails/20.jpg)

Review Considerations for Platelets
• Validation– No recommendations in LR guidance– establish documented evidence which provides a
high degree of assurance that a specific process will consistently produce a product meeting its pre-determined specifications and quality characteristics
![Page 21: Leukocyte-Reduced Blood Components Lore Fields MT(ASCP)SBB Consumer Safety Officer, DBA, OBRR, CBER September 16, 2009.](https://reader035.fdocuments.us/reader035/viewer/2022062719/56649eef5503460f94bff613/html5/thumbnails/21.jpg)
21
Review Considerations for Platelets
• Monthly QC – 1% of collections for each product type,
selected at random; if less than 400 per month, then 4 of each product type – 95% meet product standards
![Page 22: Leukocyte-Reduced Blood Components Lore Fields MT(ASCP)SBB Consumer Safety Officer, DBA, OBRR, CBER September 16, 2009.](https://reader035.fdocuments.us/reader035/viewer/2022062719/56649eef5503460f94bff613/html5/thumbnails/22.jpg)
22
Review Considerations for Platelets
Platelets, Leukocytes Reduced prepared from Whole Blood should be prepared by a method known to:– leave a residual leukocyte count of less than 8.3 x
10e5 per container and – retain a minimum of 85% of the original component
![Page 23: Leukocyte-Reduced Blood Components Lore Fields MT(ASCP)SBB Consumer Safety Officer, DBA, OBRR, CBER September 16, 2009.](https://reader035.fdocuments.us/reader035/viewer/2022062719/56649eef5503460f94bff613/html5/thumbnails/23.jpg)

Review Considerations for Platelets, Pheresis
Validation Summary
95%/95% is a statistical approach to demonstrate a 95% confidence that a product or process conforms to a prespecified standard 95% of the time
![Page 24: Leukocyte-Reduced Blood Components Lore Fields MT(ASCP)SBB Consumer Safety Officer, DBA, OBRR, CBER September 16, 2009.](https://reader035.fdocuments.us/reader035/viewer/2022062719/56649eef5503460f94bff613/html5/thumbnails/24.jpg)
24
Review Considerations for Platelets, Pheresis
• Validation (continued)– Perform when the automated blood cell separator device or
filtration method is first put into use at an establishment and/or as recommended by the automated blood cell separator device manufacturer.
– Conduct testing on the collection (parent container) and on the individual components from double and triple collections.
– Other as specified by device manufacturer
![Page 25: Leukocyte-Reduced Blood Components Lore Fields MT(ASCP)SBB Consumer Safety Officer, DBA, OBRR, CBER September 16, 2009.](https://reader035.fdocuments.us/reader035/viewer/2022062719/56649eef5503460f94bff613/html5/thumbnails/25.jpg)
25
Review Considerations for Platelets, Pheresis
• Monthly quality control (submit 2 months)
– Other as specified by device manufacturer
![Page 26: Leukocyte-Reduced Blood Components Lore Fields MT(ASCP)SBB Consumer Safety Officer, DBA, OBRR, CBER September 16, 2009.](https://reader035.fdocuments.us/reader035/viewer/2022062719/56649eef5503460f94bff613/html5/thumbnails/26.jpg)

Review Considerations for Red Blood Cells (Apheresis)
• Validation– No recommendations in LR guidance– establish documented evidence which provides a high
degree of assurance that a specific process will consistently produce a product meeting its pre-determined specifications and quality characteristics
• Monthly QC – 1% of collections for each product type, selected at
random; if less than 400 per month, then 4 of each product type
– 95% meet product standards or repeat QC
![Page 27: Leukocyte-Reduced Blood Components Lore Fields MT(ASCP)SBB Consumer Safety Officer, DBA, OBRR, CBER September 16, 2009.](https://reader035.fdocuments.us/reader035/viewer/2022062719/56649eef5503460f94bff613/html5/thumbnails/27.jpg)
27
Review Considerations for Red Blood Cells (Apheresis)
Red Blood Cells, Leukocytes Reduced should be prepared by a method known to:– leave a residual leukocyte count of less than 5.0 x
10e6 per container and – retain a minimum of 85% of the original component
![Page 28: Leukocyte-Reduced Blood Components Lore Fields MT(ASCP)SBB Consumer Safety Officer, DBA, OBRR, CBER September 16, 2009.](https://reader035.fdocuments.us/reader035/viewer/2022062719/56649eef5503460f94bff613/html5/thumbnails/28.jpg)
28
Review Considerations for Red Blood Cells (Apheresis)
• Devices that are not able to provide a pre-filtration sample.– Devices have been cleared by FDA with an alternative
method of determining product quality.– Results of alternative methods must still be recorded and
evaluated to ensure that 95% of the products are acceptable.
– Methods include:
• Computer Software (part of collection device)• Minimum absolute Red Blood Cell Volume
![Page 29: Leukocyte-Reduced Blood Components Lore Fields MT(ASCP)SBB Consumer Safety Officer, DBA, OBRR, CBER September 16, 2009.](https://reader035.fdocuments.us/reader035/viewer/2022062719/56649eef5503460f94bff613/html5/thumbnails/29.jpg)
29
Helpful Tip
Percent recovery is calculated with an absolute Red Blood Cell volume.
Volume x HCT = absolute RBC volume
![Page 30: Leukocyte-Reduced Blood Components Lore Fields MT(ASCP)SBB Consumer Safety Officer, DBA, OBRR, CBER September 16, 2009.](https://reader035.fdocuments.us/reader035/viewer/2022062719/56649eef5503460f94bff613/html5/thumbnails/30.jpg)
