Endocrine Studies Flashcards
Measures the ability of the thyroid gland to concentrate and retain circulating iodide for the synthesis of thyroid
hormone
Radioactive Iodine Uptake
Used to evaluate hyperthyroidism and/or hypothyroidism
Radioactive Iodine Uptake
What is the main contraindication for Radioactive Iodine Uptake?
Pregnant or suspected of being pregnant, unless the potential benefits of the procedure far outweigh the risks to the fetus and mother
Assesses thyroid size, assisting in the differential diagnosis of masses in the neck, base of the tongue and ruling out possible ectopic thyroid tissue.
Thyroid Scan

Thyroid Scan
Assist in the diagnosis of congenital hypothyroidism and in the diagnosis of hypo/hyperthyroidism.
Thyroid Stimulation Hormone Assay
Used to evaluate signs of hypothyroidism or hyperthyroidism and monitor response to therapy for hypo/hyperthyroidism
Free Thyroxine Concentration
A major metabolite of epinephrine
Vanillylmandelic acid
Assist in the diagnosis of neuroblastoma, ganglioneuroma, or pheochromocytoma
Vanillylmandelic Acid (VMA) Test
Done to evaluate abnormal fasting or postprandial blood glucose levels that do not clearly indicate diabetes
Oral Glucose Tolerance Test (OGTT)
The most accurate indicator of DM as it reflects serum glucose levels up to 3 months
Glycosylated Hemoglobin
This is the initial test for diabetes
Fasting Blood Glucose
Measures the blood glucose levels 2 hours after the client ingests food
2-hour Postprandial Blood Sugar Test
What is the normal value for Fasting Blood Glucose?
Normal: 70 — 110 mg/dL
