[Efficient diagnosis of hyperthyroidism, rationally justified?].

C Schümichen, G Bernhard, R Aurnhammer

    Nuklearmedizin. Nuclear Medicine
    |April 1, 1983

    Summary

    The thyrotropin-releasing hormone (TRH) test is crucial for diagnosing thyrotoxicosis, though T3 and FT4 levels also aid diagnosis. Omitting total T4 and radioiodine tests can reduce costs but may impact diagnostic accuracy.

    Area of Science:

    • Endocrinology
    • Internal Medicine
    • Diagnostic Medicine

    Context:

    • Hyperthyroidism diagnosis involves assessing various tests.
    • Prevalence of hyperthyroidism was 33% in the study population.
    • Differentiation between diffuse hyperthyroidism and autonomous adenoma is key.

    Purpose:

    • To evaluate the diagnostic value of different tests for hyperthyroidism.
    • To determine the optimal combination of tests for cost-effective diagnosis.
    • To assess the sensitivity and specificity of TRH-test, T3, FT4, and radioiodine tests.

    Summary:

    • The TRH-test is highly sensitive for thyrotoxicosis diagnosis.
    • FT4 and T3 levels have equivalent diagnostic value, with FT4 showing slight advantages.

  • Total T4 and radioiodine tests can be omitted to reduce costs, but this may compromise diagnostic certainty in about one-third of cases.

    • Impact:

    • Findings suggest optimizing diagnostic protocols for hyperthyroidism.
    • Recommendations provided for cost reduction in diagnostic workups.
    • Highlights the importance of considering test combinations for accurate diagnosis.
