Topics about Medical Tests & Examinations
  • CLINICAL TRIALS AND HRT
  • HERS involved 2,763 postmenopausal women, average age 67, who were treated for about four years. Women were randomly assigned to an estrogen/progestin combination or placebo. The study was funded by Wyeth-Ayerst Laboratories and supported by the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health (NIH).
  • COLD AGGLUTININS TEST
  • The cold agglutinins test is performed to detect the presence of antibodies in blood that are sensitive to temperature changes. Antibodies are proteins produced by the immune system in response to specific disease agents; autoantibodies are antibodies that the body produces against one of its own substances. Cold agglutinins are autoantibodies that cause red blood cells to clump, but only when the blood is cooled below the normal body temperature of 98.6°F (37°C). The clumping is most pronounced at temperatures below 78°F (25.6°C).
  • COLONOSCOPY
  • Colonoscopy is a medical procedure where a long, flexible, tubular instrument called the colonoscope is used to view the entire inner lining of the colon (large intestine) and the rectum.
  • COOMBS’ TESTS
  • Coombs' tests are blood tests that identify the causes of anemia.
  • CORTISOL TESTS
  • This test is a measure of serum cortisol (also known as hydrocortisone), or urine cortisol, (also known as urinary free cortisol), an important hormone produced by a pair of endocrine glands called the adrenal glands.
  • CREATINE KINASE TEST
  • Creatine kinase (CK or CPK) is an enzyme (a type of protein) found in muscle and brain. Normally, very little CK is found circulating in the blood. Elevated levels indicate damage to either muscle or brain; possibly from a myocardial infarction (heart attack), muscle disease, or stroke.
  • CREATININE TEST
  • Creatine is an important compound produced by the body. It combines with phosphorus to make a high-energy phosphate compound in the body. Creatine phosphate is used in skeletal muscle contraction.
  • CRYOGLOBULIN TEST
  • Cryoglobulin is an abnormal blood protein associated with several diseases. Testing for cryoglobulin is done when a person has symptoms of this protein or is being evaluated for one of the associated diseases.
