The Endocrine System Diagnostic Procedures Flashcards
Blood Serum Test
Blood test to measure the level of substances such as calcium, electrolytes, testosterone, insulin, and glucose. Used to assist in determining the function of various endocrine glands
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 a patient either orally or intravenously. Blood samples are then drawn at certain intervals to determine the ability of the patient to use glucose. Used to diabetic patients to determine their insulin response to glucose
Protein-Bound Iodine Test (PBI)
Blood test to measure the concentration of thyroxine (T[4]) circulating in the bloodstream. The iodine becomes bound to the protein in the blood and can be measured. Useful in establishing thyroid function
Radioimmunoassay (RIA)
Blood test that uses radioactively tagged hormones and antibodies to measure the quantity of hormone in the plasma
Thyroid Function Test (TFT)
Blood test used to measure the levels of thyroxine, triiodothyronine, and thyroid-stimulating hormone in the bloodstream to assist in determining thyroid function
Total Calcium
Blood test to measure the total amount of calcium to assist in detecting parathyroid and bone disorders
Two-Hour Postprandial Glucose Tolerance Test
Blood test to assist in evaluating glucose metabolism. The patient eats a high carbohydrate diet and then fasts overnight before the test. Then the blood sample is taken 2 hours after a meal
Thyroid Echography
Ultrasound examination of the thyroid that can assist in distinguishing a thyroid nodule from a cyst
Thyroid Scan
Test in which radioactive iodine is administered that localizes in the thyroid gland. The gland can then be visualized with a scanning device to detect pathology such as tumors
