Evaluation of an immunohematology testing system is necessary to show that the performance of the instrument demonstrates equivalence from a method-based perspective when compared to results of a predicate method or instrument. The ORTHO VISION® Analyzer is designed to fully automate extended antigen typing using the ID-MTS™ Gel Card (GEL) test along with a variety of ORTHO™ Sera Blood Grouping Reagents specificities. A multi-site study was conducted to evaluate the performance of the ORTHO VISION automated red cell antigen typing utilizing ORTHO Sera reagents with specific ID-MTS Gel Cards compared to the predicate test, the manual ID-MTS GEL test using the ORTHO™ Workstation. Testing included reproducibility, a measure of total precision and repeatability, which evaluates within-run test precision. This provides insight into consistency of result and degree of variability of reactivity of the automated method of testing.
