    Investigating thyroid function in patients with few symptoms is often unnecessary. Biochemical tests for thyroid dysfunction show limited value when clinical evidence is minimal.

    Area of Science:

    • Endocrinology
    • Internal Medicine
    • Clinical Chemistry

    Background:

    • Thyroid function tests are frequently requested in primary care.
    • Assessing the clinical utility of these tests is crucial for efficient healthcare resource allocation.

    Purpose of the Study:

    • To evaluate the diagnostic yield of in-vitro thyroid function tests in new patients without prior thyroid disease history.
    • To correlate the number of clinical signs and symptoms with the need for thyroid dysfunction treatment.

    Main Methods:

    • A prospective study of 500 new patients with no history of thyroid disease.
    • Clinical assessment of signs and symptoms related to thyroid dysfunction.
    • Follow-up to determine the requirement for thyrometabolic treatment based on test results.

    Main Results:

    • Only 18 out of 23 patients (78%) with five or more symptoms required treatment.
    • 1 out of 35 patients (3%) with 3-4 symptoms needed treatment.
    • 2 out of 442 patients (0.5%) with 1-2 symptoms were treated.

    Conclusions:

    • Biochemical investigation of thyroid function offers limited value in patients presenting with minimal clinical signs or symptoms.
    • Clinical assessment should guide the decision for thyroid function testing to avoid unnecessary investigations.
