Everything You Need To Know About Medical Tests

Here is complete information on blood tests, urine tests, X-rays, biopsies, CAT scans, MRI scans, and other types of medical tests -- more than 400 in all. Each entry gives a description of the test and why it's done, what happens before the test (special diets, activity restrictions, etc.), what happens during and after the test, and whether the test has risks. It also gives normal and abnormal results (and explains what they mean) and other tests that may need to be done. Eye-catching logos attract readers to practical sidebars that give self-help tips, practical explanations of important body organs and glands, and insights into illnesses.
