Tests & Procedures

Tests and Procedures: A

  • Antegrade Pyelogram

    An antegrade pyelogram is an imaging test to find a blockage (obstruction) in the upper urinary tract. Your urinary tract includes the kidneys, ureters, and bladder. The ureters are the narrow tubes that carry urine from the kidneys to the bladder. During the test, the radiologist injects a contrast dye through a needle that is placed through the flank area of your back. The radiologist uses X-ray images to watch the contrast dye as it moves from the kidney into the ureter and then to the bladder.

  • Antidiuretic Hormone

    This test measures the amount of antidiuretic hormone (ADH) in your blood. ADH regulates your body's balance of water.

  • Antimitochondrial Antibody and Antimitochondrial M2 Antibody

    This test looks for certain substances in your blood that may mean you have a form of liver disease.

  • Antimyocardial Antibody

    This test checks the level of a certain antibody in your blood that can indicate heart damage. The antibodies show up before symptoms appear.

  • Antinuclear Antibody

    This blood test is done to help your doctor diagnose a type of illness called an autoimmune disease.

  • Antiphospholipid Antibody

    This test checks for antibodies that can help diagnose a condition with abnormal blood clots or an autoimmune disease.

  • Antithrombin (Activity and Antigen)

    The antithrombin activity and antigen tests are used to help find out what may be causing abnormal blood clots in your body.

  • Antitissue Transglutaminase Antibody

    This test screens for celiac disease and also helps your healthcare provider monitor your condition if you have this disease.

  • Aortic Dissection Repair

    An aortic dissection is a tear (dissection) in the wall of your body’s main artery, the aorta. Treatment will depend on where the tear is located. You will most likely need surgery if the tear is on the ascending aorta. This is the part of the aorta that goes up through your chest toward your head.

  • Aortic Valve Replacement: Minimally Invasive

    A minimally invasive aortic valve replacement is a surgery to replace a badly working aortic valve with an artificial valve. The aortic valve is one of the heart’s four valves. The valves help blood flow through the heart’s 4 chambers and out to your body normally. The surgery is called “minimally invasive” because it uses a smaller incision than a traditional open repair.
