Test Details

TSH is produced by the pituitary gland and stimulates the thyroid to produce the hormones thyroxine (T4) and triiodothyronine (T3). The thyroid is a butterfly shaped gland that is found near your throat. It produces hormones that are needed to regulate your body’s energy usage. These hormones are also involved in managing your weight and keeping your temperature at a normal level. They also affect your mood and muscle strength. When too much or too little TSH is produced, it impacts the levels of other thyroid hormones. The TSH test can help detect if you have a thyroid disorder like hyperthyroidism or hypothyroidism.

Finger-stick dried blood spot is the whole blood collected from the end of the finger by using a small lancet. This is the capillary blood, which is a mixture of both red blood cells, white blood cells and serum/ plasma, in addition to all the nutrients, hormones and oxygen. Dried blood spot offers ease and convenience of sample collection.
