Quality-assured blood testing
Export Indicator
This indicator measures the extent of quality-assured screening of blood units at different levels of the health system.
- Unsafe blood transfusion is still a concern, especially in low- and middle-income countries where the prevalence of transfusion-transmissible infections is high and the quality and coverage of blood screening are inadequate.
- Less than 100% screening indicates lack of or inappropriate laboratory screening and flags the risk of transmission through unsafe blood supplies.
