Thyroid Function Tests
TSH (Thyroid Stimulating Hormone)
TSH is produced by the pituitary gland and controls thyroid gland activity. Being the reverse of the other indicators, a high level is seen in Hypothyroidism and low level is seen in Hyperthyroidism.
Free T4 is a hormone produced by the thyroid glands. Thyroid gland dysfunction will affect the levels of Free T4. It plays an important role in regulating the metabolic processes of the body. High levels are seen in a condition known as Hyperthyroidism with associated tremors, tiredness, weight loss, sweating and anxiety. Low levels, due to reduced production of Free T4, will lead to a condition known as Hypothyroidism with features such as slow mental activity, mood depression, lethargic appearance, physical slowness and weight gain.
Glucose is the main carbohydrate in the blood used for energy by the body cells. The level of blood glucose is influenced by food intake. Glucose in adequate levels is essential for normal body functions. Its level is controlled by the action of a hormone known as insulin, which is produced by the pancreas. A high level of glucose above the normal range is indicative of diabetes. Another test, Glucose Tolerance Test (GTT) is usually performed to help confirm diagnosis of diabetes.
