What is a Thyroid Profile Test?
What is a Thyroid Profile Test?
A Thyroid Profile Test measures the levels of three key hormones produced by your thyroid gland: T3 (Triiodothyronine), T4 (Thyroxine), and TSH (Thyroid Stimulating Hormone). Together, these three values give a complete picture of how well your thyroid is functioning.
The thyroid is a butterfly-shaped gland in your neck that controls your metabolism, energy levels, body weight, mood, and heart rate. When it produces too much or too little hormone, it affects almost every system in your body.

Is TSH alone enough to test thyroid function?
Is TSH alone enough to test thyroid function?
TSH is the most sensitive marker for thyroid disorders and is often tested first. However, a full Thyroid Profile (T3, T4, TSH) gives a more complete picture — especially when diagnosing the type of thyroid disorder or monitoring treatment.
What does a high TSH level mean?
What does a high TSH level mean?
A high TSH level generally means your thyroid gland is underactive (hypothyroidism). The pituitary gland produces more TSH to stimulate a sluggish thyroid. This is typically associated with fatigue, weight gain, and cold sensitivity.
What does a low TSH level mean?
What does a low TSH level mean?
A low TSH level usually indicates an overactive thyroid (hyperthyroidism). The pituitary gland reduces TSH production because the thyroid is already producing too much hormone. Symptoms include weight loss, rapid heartbeat, and anxiety.
How often should I get a thyroid test?
