North American Pretransfusion Testing Practices, 2001–2004: Results From the College of American Pathologists Interlaboratory Comparison Program Survey Data, 2001–2004

Abstract

Most North American laboratories currently favor tube methods when performing ABO grouping, Rh typing, antibody screening, and crossmatching. However, there has been a significant increase in the use of gel-based methods in recent years, especially for antibody detection and crossmatching. Data collection and data analysis of CAP Interlaboratory Comparison Program Survey results allow for assessment of laboratory proficiency and provide insights into current North American practice trends in pretransfusion compatibility testing.
