Summary
Pooling blood donations for viral genome amplification assays can reduce costs and testing volume. This method allows for efficient screening of large numbers of units for low-prevalence viruses, enhancing blood safety.
Area of Science:
- Virology
- Molecular Biology
- Public Health
Background:
- Current viral genome amplification assays for blood donations are costly and impractical for individual screening.
- Serological screening programs exist but can be enhanced with genetic testing for improved blood safety.
Purpose of the Study:
- To introduce a cost-effective and efficient method for screening large volumes of blood donations for multiple low-prevalence viruses.
- To demonstrate the feasibility of pooling specimens for viral screening to improve blood safety and timeliness of component release.
Main Methods:
- Describing the preparation of intersecting pools of specimens for simultaneous testing.
- Utilizing amplification assays on prepared specimen pools to detect viral genomes.
Main Results:
- The proposed pooling strategy significantly reduces the number of tests required for screening large numbers of blood donations.
- Timely release of blood components is achievable with adequate test sensitivity and specificity.
Conclusions:
- Specimen pooling offers a viable solution to overcome the cost and complexity barriers of individual viral genome amplification assays.
- This approach enhances current blood screening programs by incorporating genetic testing, thereby improving blood safety and enabling broader viral surveillance.
