|---|---|
 basal metabolic rate (BMR) | Somewhat outdated test to measure the energy used when the body is in a state of rest. |
| blood serum test | blood test to measure the level of substances such as calcium, electrolytes, testosterone, insulin, and glucose. |
| fasting blood sugar (FBS) | Blood test to measure the amount of sugar circulating throughout the body after a 12 hour fast |
| glucose tolerance test (GTT) | Test to determine the blood sugar level. A measured dose of glucose is given to the patient either orally or intravenously. Blood samples are taked at certain intervals to determine the ability of the patient to use glucose. |
| protein-bound iodine test (PBI) | Blood test to measure the concentration of thyroxine circulating in the bloodstream. The iodine becomes bound to the protein in the blood and can be measured. Useful in establishing thyroid function. |
| radioactive iodine uptake test (RAIU) | Test in which radioactive iodine is taken orally or intravenously. The amount that is eventually taken into the thyroid gland is measured to assist in determining thyroid function. |
| radioimmunoassay (RIA) | Test used to measure the levels of hormones in the plasma of the blood. |
| serum glucose tests | Blood test performed to assist in determining insulin levels and useful for adjusting medication dosage. |
| thyroid echogram | Ultrasound examination of the thyroid that can assist in distingushing a thyroid nodule from a cyst. |
| thyroid function test(TFT) | Blood test used to measure the levels of T3 and T4 and TSH in the bloodstream to assist in determining thyroid function. |
| thyroid scan | Test in which a radioactive iodine is administered that localizes in the thyroid gland. The gland can then be vusualized with a scanning device to detect pathology such as tomors. |
| total calcium | Blood test to measure the total amount of calcuum to assist in detecting parathyroid and bone disorders. |
| two-hour postprandial glucose tolerance test | blood test to assist in evaluation glucose metabolism. The patient eats a high carbohydrate diet and fasts overnight before the test. A blood sample is then taken 2 hours after a meal. |
