Thyroid Profile Test (TFT) in Madurai - Price & Details

The thyroid gland is a "butterfly-shaped" organ present in the neck region. It releases certain types of hormones that are useful for the regulation of your body's metabolism rate, digestive functions and other metabolic activity.

The three hormones that are analysed in a thyroid profile test are as follows:

• TSH - Thyroid Stimulating Hormone or TSH is the hormone responsible for activation of the thyroid gland. It works on a feedback loop mechanism. This hormone is produced by the pituitary gland and acts on the thyroid gland to stimulate it into producing thyroid gland hormones.

• T3 and T4 - Triiodothyronine (T3) and tetraiodothyronine (T4) are the thyroid hormones that regulate the BMR of your body, maintenance of bones, digestive and heart functions, and brain and muscle development. Hypothyroidism or hyperthyroidism can be caused when there is an imbalance in these hormones.

The normal range of the above-mentioned tests is as follows:

• T3: 0.97-1.80 ng/mL
• T4: 5.53-14.00 ug/dL
• TSH: 0.46-4.68 uIU/ml

If your TSH levels are high, it is probably a sign that your thyroid gland is not functioning properly. To assess further, the T3 and T4 levels are checked. A complete thyroid profile test can be used to diagnose hyperthyroidism, hypothyroidism or other thyroid disorders.

There is no fasting required if you are going for a thyroid profile test because the level of thyroid hormones in your bloodstream is not affected by the food you consume. However, there may be some other preparation steps that your doctor may ask you to follow.

During the Thyroid Profile Test

During the thyroid profile test, an experienced phlebotomist will come to your home for sample collection. We use vein finders to comfortably locate the vein. Once done, a sterile syringe is used to draw blood from that vein and it is collected in a collection tube for further testing. Anti-coagulating agents are present in the tune to prevent blood clotting.
