Approved by the Professor
accuracy of a test - CORRECT ANSWER: does the test measure what is is designed to
measure
ACTH (adrenocorticotropic hormone) - CORRECT ANSWER: Stimulates adrenal cortex
to release glucocorticoids (cortisol)
response to stress
fights infection
regulates blood sugar and blood pressure and metabolism
ACTH stim test - CORRECT ANSWER: 250 mcg Cosyntropin; measure cortisol before
& 30 & 60 min after injxn; pre or post >18: R/O adrenal insuff
Addison's disease - CORRECT ANSWER: a condition that occurs when the adrenal
glands do not produce enough cortisol or aldosterone
Aldosterone - CORRECT ANSWER: "salt-retaining hormone" which promotes the
retention of Na+ by the kidneys. na+ retention promotes water retention, which
promotes a higher blood volume and pressure
Alkaline phosphatase - CORRECT ANSWER: alkaline phosphatase levels are high and
the results of liver tests are normal, the problem may be a bone disorder, such as
Paget's disease of bone. This disease makes your bones unusually large and weak,
causing them to break more easily
, Anion Gap - CORRECT ANSWER: Difference between the concentrations of serum
cations and anions: determined by measuring the concentrations of sodium cations and
chloride and bicarbonate anions.
antidiuretic hormone (ADH) - CORRECT ANSWER: influences the absorption of water
by kidney tubules
antinuclear antibody (ANA) - CORRECT ANSWER: test to identify antibodies that attack
the nucleus of the individual's own body cells (auto-antibodies)
VERY SPECIFIC NOT SENSITIVE
Antithyroidglobulin antibody - CORRECT ANSWER: level of antibodies
protein found in thyroid cells
less than 116IU
arthroscopy - CORRECT ANSWER: the visual examination of the internal structure of a
joint
B cell lymphocytes - CORRECT ANSWER: mature into plasma cells to secrete
antibodies
Bands - CORRECT ANSWER: immature neutrophils
released after injury or inflammation, ACUTE RESPONSE
basophils - CORRECT ANSWER: A circulating leukocyte that produces histamine.
bone scan - CORRECT ANSWER: A test that detects areas of increased or decreased
bone metabolism; test is performed to identify abnormal processes involving the bone
such as tumor, infection, or fracture.
