Medical knowledge at the end of the twentieth century continues to grow at an exponential rate. Keeping up with this growth is a daunting challenge for the busy clinician. This site provides an efficient way for all health care professionals to review the latest advances in medical diagnosis and treatment.

In clinical medicine, choosing the appropriate diagnostic tests and interpreting the results knowledgeably is often the difference between success and failure, especially when treating seriously ill patients. The diagnostic-medical-tests.com provides the latest information about commonly used tests in a format that is clear, concise, and easy to access.

Many of the newer diagnostic tests have had a dramatic effect on patient care. Changes in the diagnostic approach to patients suspected of having acute appendicitis provide a good example of how improvements in technology and increasing skill in interpreting imaging studies have changed patient care. Before abdominal and pelvic ultrasound examinations and computed tomography (CT) scanning were generally available, surgeons operating on a presumed diagnosis of appendicitis had an 80% diagnostic accuracy. Twenty percent of surgeries for possible appendicitis revealed no abnormalities, nor did they indicate that some other process (such as diverticulitis, pelvic inflammatory disease, mesenteric adenitis, and Crohn's disease) was responsible for the patient's symptoms. However, improving the preoperative diagnostic accuracy by waiting until symptoms become more definite risks a ruptured appendix. Today, the ready availability of abdominal ultrasound and CT scanning has greatly changed the management of these patients. When clinical findings are equivocal, an immediate ultrasound can be obtained. When the ultrasound suggests appendicitis, surgery is often done at an earlier stage in the disease than it might have otherwise. If the ultrasound examination is not diagnostic, a CT scan may clarify the diagnosis; sometimes it diagnoses appendicitis when the ultrasound is normal. With this approach, the diagnostic accuracy in patients with acute appendicitis is over 95% instead of 80%, meaning that thousands of patients every year can avoid unnecessary surgery and can sooner undergo safer and more appropriate therapy.

The diagnostic-medical-tests.com, is a valuable guide to understanding how and when these newer diagnostic approaches are used and how to interpret the results.
