Overview
Laboratory findings consistent with the diagnosis of Hashimoto's thyroiditis usually include increased thyroid stimulating hormone, decreased free T3 and free T4, and anti-thyroid peroxidase antibodies.
Laboratory Findings
Laboratory findings consistent with the diagnosis of Hashimoto's thyroiditis usually include increased thyroid stimulating hormone, decreased free T3 and free T4, and Anti-thyroid peroxidase antibodies.[1][2]
Thyroid hormones
- Increased Thyroid-stimulating hormone (TSH)
- Decreased Free T3 and Free T4
- TSH may be decreased in the transient hyperthyroid state[3]
Thyroid antibodies
- Anti-thyroid peroxidase antibodies (anti-TPO) (correlates with the disease severity)
- Anti-thyroglobulin antibodies (anti-Tg)
- Anti-microsomal antibodies can help obtain an accurate diagnosis[4]
Diagnostic findings of Hashimoto's thyroiditis
| Thyroid function test | ↓TSH ↑ T3 and T4 | In transient hyperthyroidism |
| ↑ TSH ↓ T3 and T4 | In the hypothyroid state | |
| Antibodies | Anti-thyroid peroxidase antibodies | Positive |
| Anti-thyroglobulin antibodies | Positive | |
| Anti-microsomal antibodies | Positive | |
| Radioiodine reuptake | I-123 reuptake | ↓ |
