Laboratory testing in thyroid disorders.
| Laboratory | R-BPPV | NR-BPPV | p value |
|---|---|---|---|
| n = 61 | n = 79 | ||
| TSH (n.v. 0·35-2.80 μIU/ml) | 1.8 ± 0.9 | 1.4 ± 0.9 | > 0.05 |
| f-T3 (n.v. 2.3-4.2 pg/ml) | 2.9 ± 0.6 | 2.5 ± 0.4 | > 0.05 |
| f-T4 (n.v. 8.5-15.5 pg/ml) | 10.8 ± 4.3 | 8.8 ± 2.6 | > 0.05 |
| TPO-Ab (n.v. < 5.6 IU/ml) | 249.6 ± 393 | 107.1 ± 213.8 | 0.0117 |
| TG-Ab (n.v. < 4.1 IU/ml) | 132.1 ± 162 | 22.3 ± 54.3 | 0.0025 |
Hormonal dosages and thyroid autoantibodies: comparison between the two groups of BPPV patients suffering from thyroid diseases. Statistical significance was set at p < 0.05. TSH: thyroid stimulating hormone; f-T3: triiodothyronine; f-T4: free thyroxine; TG-Ab: Thyroglobulin antibodies; TPO-Ab: thyroid peroxidase antibodies; BPPV: benign paroxysmal positional vertigo; R-BPPV: recurrent BPPV; NR-BPPV: non-recurrent BPPV.
