About this test

Purpose of the Test

  • Diagnose Thyroid Issues: Identifies Graves' disease, Hashimoto's disease, and other thyroid dysfunction.
  • Monitor Treatment: Checks if medication for thyroid disorders is working effectively.
  • Screening: Used for newborns to detect congenital hypothyroidism

Understanding Results

  • High T4 levels: May indicate hyperthyroidism (overactive thyroid), Graves' disease, or thyroiditis.
  • Low T4 levels: Often suggest hypothyroidism (underactive thyroid) or iodine deficiency.
  • Interfering Factors: Pregnancy, birth control pills, and certain medications (like estrogen or steroids) can influence total T4 levels.

What to Expect

The test is a standard blood draw (venipuncture) with minimal risk. It is frequently ordered alongside TSH (Thyroid Stimulating Hormone) and T3 tests for a complete picture.

Preparation

  • No fasting is needed for this test. You can book any available slot.
  • Keep your doctor’s prescription or test request handy if you have one, and take regular medicines as your doctor has advised.
