Thyroid Profile

The Thyroid Profile is a blood test panel that evaluates the functioning of the thyroid gland, a small butterfly-shaped gland located at the base of your neck. The thyroid produces hormones that control the body’s metabolism, energy levels, heart rate, temperature, and more.

This test typically includes the measurement of three major hormones:

• TSH (Thyroid Stimulating Hormone)

• T3 (Triiodothyronine)

• T4 (Thyroxine)

🔹

Key Components of Thyroid Profile:

1. TSH (Thyroid Stimulating Hormone)
   Produced by the pituitary gland; stimulates the thyroid to produce T3 and T4
   High TSH = Underactive thyroid (Hypothyroidism)
   Low TSH = Overactive thyroid (Hyperthyroidism)
   Normal Range: 0.4 – 4.0 mIU/L

2. T3 (Triiodothyronine)
   Active form of thyroid hormone; helps regulate metabolism
   Abnormal levels indicate thyroid imbalance
   Normal Range: 80 – 200 ng/dL

3. T4 (Thyroxine)
   Most abundant thyroid hormone; affects metabolism, growth, and energy
   Normal Range: 5.1 – 14.1 µg/dL

🔹

Why It’s Done:

• Diagnose thyroid disorders

• Evaluate symptoms like fatigue, weight changes, hair loss, irregular periods, or anxiety

• Monitor thyroid hormone replacement therapy

• Screen in pregnancy or in patients with autoimmune diseases

🔹

Procedure:

• A blood sample is collected from a vein

• No special preparation is usually required (unless specified by your doctor)

• Results are typically available within a few hours to one day

🔹

Advantages:

• Detects hypothyroidism or hyperthyroidism early

• Helps track treatment progress

• Crucial for overall hormonal and metabolic health

The Thyroid Profile is an essential test that helps ensure your thyroid is functioning properly and supports early intervention for hormonal imbalances that could affect your overall well-being.
