Overview

Screening for Goiter initially involves physical examination followed by blood tests for free T4 and TSH and finally thyroid scan, ultrasound and biopsy to rule out malignanacy.

Screening

• Screening for Goiter includes the following approaches and progresses to the next approach based on the result of earlier screening procedure:
  • Physical exam:
    • Involves the assessment of the size and the extent of enlargement of the thyroid gland. If the enlargement is positive, blood tests for Free T4 and TSH are evaluated.
  • Blood Tests:
    • Blood tests are carried out in order to determine whether the Goiter is affecting the production of thyroid hormone.
      • Free thyoxine (T4)
      • Thyroid stimulating hormone (TSH)
  • Further evaluation to rule out malignancy:
    • Based on the results of the physical exam and blood tests, further evaluation involving the following is advised in order to rule out malignant transformation of the gland:
      • Thyroid scan
      • Ultrasound
      • Biopsy of the gland
