Endocrine common diagnostic tests & procedures Flashcards
Reflection of the average blood glucose level over the past 2 to 3 months reported by the same units (mg/dL) seen on glucose meters; directly correlates to HbA1c results
Average blood glucose (eAG):
Test of blood glucose levels after a fast of 8 to 12 hours, used to screen for diabetes; also called FBS, or fasting blood sugar
Fasting blood glucose (FBG):
Test of blood glucose from a drop of capillary blood obtained by pricking the finger; also called finger stick blood glucose (FSBG)
Finger stick blood sugar (FSBS):
Reflection of the average blood glucose level over the past 2 to 3 months by measuring the amount of hemoglobin with sugar attached to it; reported as a percentage
Glycosylated hemoglobin (HbA1c):
Nuclear medicine study that measures how rap- idly radioactive iodine is taken up from the blood after oral or intravenous administration
Radioactive iodine uptake:
Reflection of thyroid function by measuring levels of thyroid-stimulating hormone (TSH), triiodothyronine (T3), and thyroxine (T4)
Thyroid function test:
Radiographic evaluation of the thyroid after a radioactive substance is injected; identifies thyroid size, shape, position, and function
Thyroid scan:
Measure of the ability of the thyroid gland to concentrate and retain circulating iodine for synthesis of thyroid hormone
Thyroid-stimulating hormone (TSH):
The person has fasted for a designated time, usually 8 to 12 hours. Blood is drawn from a vein with a needle and syringe or with a device called a Vacutainer (a needle attached to a vacuum-sealed tube). The blood specimen is tested in the laboratory.
FBS:
Blood sugar may be checked at any time but is usually checked just prior to meals. A drop of capillary blood is obtained by poking the tip of the fin- ger with a lancet (tiny, sharp blade). The blood is tested immediately using an instrument called a glucometer
FSBS:
