Diagnostic specialties

Clinical laboratory sciences are the clinical diagnostic services which apply laboratory techniques to diagnosis and management of patients. In the United States these services are supervised by a pathologist. The personnel that work in these medical laboratory departments are technically trained staff who do not hold medical degrees but who usually hold an undergraduate medical technology degree who actually perform the tests assays and procedures needed for providing the specific services. Subspecialties include Transfusion medicine Cellular pathology Clinical chemistry Hematology Clinical microbiology and Clinical immunology.
Pathology as a medical specialty is the branch of medicine that deals with the study of diseases and the morphologic physiologic changes produced by them. As a diagnostic specialty pathology can be considered the basis of modern scientific medical knowledge and plays a large role in evidencebased medicine. Many modern molecular tests such as flow cytometry polymerase chain reaction PCR immunohistochemistry cytogenetics gene rearragements studies and fluorescent in situ hybridization FISH fall within the territory of pathology.
Radiology is concerned with imaging of the human body e.g. by xrays xray computed tomography ultrasonography and nuclear magnetic resonance tomography. Clinical neurophysiology is concerned with testing the physiology or function of the central and peripheral aspects of the nervous system. These kinds of tests can be divided into recordings of spontaneous or continuously running electrical activity or stimulus evoked responses. Subspecialities include Electroencephalography Electromyography Evoked potential Nerve conduction study and Polysomnography. Sometimes these tests are performed by techs without a medical degree but the interpretation of these tests is done by a medical professional.
