Overview
A detailed evaluation of a patient with clinical symptoms of hyperthyrodism must be done in order to make an accurate diagnosis.
Diagnostic approach
- In the presence of relative clinical symptoms and signs for hyperthyroidism, a diagnostic approach must be taken to accurately diagnosis and manage the disease.[1][2][3]
- The following algorithm summarizes the diagnostic approach for suspected hyperthyroidism.
| Suspected Hyperthyroidism | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Measure serum TSH and free T4 | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Normal TSH & free T4 | ↓ TSH & ↑ free T4 | ↓ TSH & Normal free T4 | Normal or ↑ TSH & ↑ free T4 | ||||||||||||||||||||||||||||||||||||||||||||||||||||
| Hyperthyroidism ruled out | Hyperthyrodism | Measure free T3 | TSH secreting pituitary tumor, Thyroid hormone resistance or Assay interference | ||||||||||||||||||||||||||||||||||||||||||||||||||||
| Measure TSH receptor antibodies | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
| ↑ free T3 | Normal free T3 | ||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Present | Absent | T3 Toxicosis | Sub-clinical Hyperthyrodism | ||||||||||||||||||||||||||||||||||||||||||||||||||||
Graves' Disease | Assess radioiodine uptake, obtain radionuclide scan, or both | Evolving Graves' disease, Evolving toxic nodular goiter, Excess thyroid hormone intake, or Non thyroidal illness | |||||||||||||||||||||||||||||||||||||||||||||||||||||
| Homogeneous increased uptake | Patchy uptake or single nodule | Low or no uptake | |||||||||||||||||||||||||||||||||||||||||||||||||||||
Graves disease | Toxic nodular goiter | Subacute thyroiditis, Excess thyroid hormone intake, or HCG secreting tumor | |||||||||||||||||||||||||||||||||||||||||||||||||||||
The presence of at least one of the following findings in a hyperthyroid patient is definitive for Graves' disease:[4]
- Detectable TSH receptor antibodies (TRAbs) in the serum
- Evidence of ophthalmopathy and/or dermopathy
- Diffuse and increased RAIU
