Topics about Medical Tests & Examinations

CT-GUIDED BIOPSY
Computed tomography (CT) is a process that images anatomic information from a cross-sectional plane of the body. Biopsy is the process of taking a sample of tissue from the body for analysis. CT is commonly used in biopsies to provide images that help guide the tools or equipment necessary to perform the biopsy to the appropriate area of the body.

CULTURE-FAIR TEST
A culture-fair test is test designed to be free of cultural bias, as far as possible, so that no one culture has an advantage over another. The test is designed to not be influenced by verbal ability, cultural climate, or educational level.

CYSTOMETRY
Cystometry is a test of bladder function in which pressure and volume of fluid in the bladder is measured during filling, storage, and voiding.

CYSTOSCOPY
Cystoscopy (cystourethroscopy) is a diagnostic procedure that is used to look at the bladder (lower urinary tract), collect urine samples, and examine the prostate gland. Performed with an optic instrument known as a cystoscope (urethroscope), this instrument uses a lighted tip for guidance to aid in diagnosing urinary tract disease and prostate disease. Performed by a urologist, this surgical test also enables biopsies to be taken or small stones to be removed by way of a hollow channel in the cystoscope.

DELAYED HYPERSENSITIVITY SKIN TEST
A delayed hypersensitivity test (DHT) is an immune function test measuring the presence of activated T cells that recognize a certain substance.

DES EXPOSURE
DES (diethylstilbestrol) is a hormone that was prescribed for pregnant women in the 1950s and early 1960s. Many years later, doctors discovered that the daughters of the women who received DES were at high risk for a variety of problems, including infertility, premature labor, and cancer of the vagina and cervix.

DIAGNOSING CORONARY HEART DISEASE
The diagnosis of coronary heart disease is based on patient history, physical examination, symptoms and the results of testing. Many times, coronary heart disease produces few if any symptoms. For this reason, all adults should have regular appointments with a physician. Such a visit should involve a discussion of lifestyle, blood pressure and weight measurements, and specific blood tests to evaluate your risk for heart disease.

DIAGNOSTIC TESTS FOR OSTEOPOROSIS
To diagnose osteoporosis or "bone thinning", doctors ask patients about their medical history, perform a physical examination and order certain laboratory tests to make sure there are no other bone problems. The physician may then send the patient for a bone density measurement. An abnormally low bone density suggests that the patient has osteoporosis.
