Across
- 4. a blood draw that measures the amount of hormone produced by the pituitary gland to control the thyroid gland. It is used as the initial, primary screen to diagnose an underactive (high TSH) or overactive (low TSH) thyroid by detecting when the gland is not acting normally.
- 5. medicine test that uses a radioactive tracer (iodine or technetium) to map the structure and function of the thyroid gland, typically to investigate nodules or overactive/underactive function. The patient swallows a tracer pill (or gets an injection) 4-24 hours before a gamma camera captures images of the neck, showing how thyroid cells take up the tracer
- 6. is a common blood test used to diagnose thyroid disorders, such as hyperthyroidism (overactive) or hypothyroidism (underactive). It measures free or total
Down
- 1. abstaining from food and beverages (except water) for 8–12 hours, typically done in the morning to measure baseline levels of glucose or lipids. A phlebotomist draws blood from a vein, often testing for diabetes
- 2. how well your body handles a sugary drink, typically screening for prediabetes, diabetes, or gestational diabetes. After fasting, your blood is drawn, you drink a high-glucose liquid, and your blood is tested periodically over 1–3 hours to see how quickly your body clears the sugar. A positive sign (indicating diabetes) is generally a blood sugar level of 200 mg/dL or higher 2 hours after the drink
- 3. the blood, usually after a quick venipuncture in the arm, looking for levels that are too high (hyper) or too low (hypo) compared to normal ranges
