Overview
Laboratory findings consistent with the diagnosis of silent thyroiditis usually include increased free T3, free T4, decreased thyroid stimulating hormone in thyrotoxicosis phase and decreased free T3, free T4, increased thyroid stimulating hormone in hypothyroidism phase. Anti-thyroid peroxidase antibody is usually high.
Laboratory Findings
Laboratory findings consistent with the diagnosis of silent thyroiditis usually include increased free T3, free T4, decreased thyroid stimulating hormone in thyrotoxicosis phase and decreased free T3, free T4, increased thyroid stimulating hormone in hypothyroidism phase. Anti-thyroid peroxidase antibody is usually high.[1][2]
Thyroid hormones
In thyrotoxicosis phase:
- Increased Free T3 and Free T4
- Decreased Thyroid-stimulating hormone (TSH)
In hypothyroidism phase:
- Decreased Free T3 and Free T4
- Increased Thyroid-stimulating hormone (TSH)
Thyroid antibodies
Anti-thyroid peroxidase antibodies (anti-TPO) are usually high.
