Man screening donated blood for infections

Donated blood should always be screened

All donated blood should always be screened for HIV, hepatitis B, hepatitis C and syphilis prior to transfusion. Yet 25 countries are not able to screen all donated blood for one or more of these infections. Testing is not reliable in many countries because of staff shortages, poor quality test kits, irregular supplies, or lack of basic quality in laboratories.
