Comparisons of RAIU, TSH, Tgoff, and TgAb Levels Among 3 Primary Causes of Unexplained Hyperthyroglobulinemia in TT-DTC Patients (n = 254)
| Factor | Thyroid remnant | Biochemical disease | Structural or functional disease | P |
| RAIU (%) | 5.2 ± 3.2 | 4.6 ± 3.1 | 4.9 ± 3.3 | 0.964 |
| TSH (mIU/L) | 100 (49.5–100) | 100 (49.6–100) | 100 (56.6–100) | 0.225 |
| Tgoff (ng/mL) | 17.0 (12.7–25.5) | 26.9 (16.6–48.9) | 33.5 (22.2–67.8) | 0.000 |
| TgAb (IU/mL) | 10 (10–64.4) | 10 (10–80.34) | 10.5 (10–62.9) | 0.227 |
RAIU = radioactive iodine uptake; IQR = interquartile range.
Data are mean ± SD or median followed by range in parentheses.
