Relationship between Turbo™ TBI, Thyretain^® TBI, and TRAb results.

Turbo™ TBI reporter bioassay inhibition range (% inhibition)	40–50 N = 38	51–60 N = 32	61–70 N = 53	71–100 N = 89	Total N = 212
Thyretain® TBI positive	15 (39.5%)	19 (59.4%)	48 (90.6%)	86 (96.7%)	168 (79.2%)
TRAb positive	14 (36.8%)	10 (31.3%)	39 (73.6%)	75 (84.3%)	138 (65.1%)

TBI ranges sort the assay results. Turbo™ TBI values were tested using the Mann–Whitney U (MWU) test: p _TRAb <0.001; TRAb shows moderate strength (r _TRAb = 0.43).
