Why do we screen blood donors?
Screening for transfusion-transmissible infections (TTIs) to exclude blood donations at risk of transmitting infection from donors to recipients is a critical part of the process of ensuring that transfusion is as safe as possible.
Why is donor screening important?
A fundamental part of preventing transfusion transmitted infections (TTIs) is to notify and counsel reactive donors. Donor notification and counselling protect the health of the donor and prevent secondary transmission of infectious diseases.
What is donor screening test?
INTRODUCTION. Laboratory testing of donated blood prior to transfusion is intended to ensure that recipients receive the safest possible blood products. This review will discuss the various protocols in place for the laboratory testing of donated blood, with emphasis on screening for infectious agents.
What is the screening and testing procedure of blood?
The objective of blood screening is to detect markers of infection in order to prevent the release of infected blood and blood components for clinical use. Blood screening strategies are designed to assure the safety of blood units, but should not be used for notifying blood donors of reactive test results.

What is the donor screening process?
The donor screening process also protects the safety of the transfusion recipient by identifying eligible donors who meet specific criteria to help ensure blood safety.
How are blood donors screened for transmissible diseases?
Each donor is screened for risk of transmissible disease by questionnaire, and each unit of blood donated in the U.S. is routinely screened for various infectious disease pathogens, including five transfusion–transmitted viruses, using nine laboratory tests.
