The performance limits of acceptability required by CLIA for proficiency testing of participants are as follows: ABO grouping, 100%; Rh D typing, 100%; antibody detecting, 80%; antibody identifying, 80%; and crossmatching, 100%.
From 2005 to 2010, the most respondents reporting an ABO grouping result was 3793.
The ABS2000 is the only FDA cleared instrument which performs ABO grouping
, Rh typing, antibody screening and crossmatching.
On the other hand, it is important to be sure that every technologist can recognize an ABO grouping
discrepancy or mixed field agglutination.
In other words, perform the ABO grouping
on the intended recipient a second time and dispense with crossmatching entirely.
