Learn About Our Donor Screening Process
Blood products are collected from individuals (subjects) who are screened in accordance with the Food and Drug Administration’s current requirements and recommendations for donors of blood products intended for transfusion in the U.S. Health history of prospective subjects is assessed before each collection by soliciting the individual’s responses to more than 50 questions on Key Biologics’ Health History Record which includes all questions on the current FDA-approved health history questionnaire that is used to screen donors of transfusable components. Key Biologics’ health history record also includes several questions approved by the FDA to screen donors of tissue for transplantation.
Most blood products are collected under protocols approved by an Institutional Review Board with specific inclusion/exclusion criteria that must also be assessed to determine the potential subject’s eligibility to provide a specific blood product. Subjects must be found eligible in accordance with all the guidelines for screening donors of transfusable products unless the final use of the product and protocol’s inclusion/exclusion criteria allows an exception. Screening materials and protocol inclusion/exclusion criteria will be provided to the customer for review upon request and may be modified to meet customer specifications if subject safety would not be adversely impacted by the changes.
Infectious disease screening is performed with each product collection using blood samples collected concurrently with the product. Infectious disease screening is outsourced to a laboratory inspected and licensed by the FDA. Test results are generally received and provided to the customer on the day following collection, usually before noon. If requested by the customer, infectious disease screening can be performed in advance of collection, and products will be released for shipment based on those results. Additionally, a customer may request additional testing of prospective subjects to qualify them for the intended use of the product.
