Improvement in ELISA sensitivitya
Abbreviations: E = EUROIMMUN; FACS = fluorescence-activated cell sorting; O = Oxford; R = RSR/Kronus
The ELISA-R is significantly less sensitive than FACS or CBA-O (McNemar's test of paired proportions, corrected for multiple comparisons with a Bonferroni test) using the recommended cutoff of 5.0 U/mL, but not when the cutoff is reduced to ≥1.6 U/mL.
