Pathology is the study of disease and injury. The word pathology also refers to the study of disease in general, incorporating a wide range of biology research fields and medical practices. However, when used in the context of modern medical treatment, the term is often used in a narrower fashion to refer to processes and tests that fall within the contemporary medical field of "general pathology", an area that includes a number of distinct but inter-related medical specialties that diagnose disease, mostly through analysis of tissue and human cell samples. Idiomatically, "a pathology" may also refer to the predicted or actual progression of particular diseases, and the affix pathy is sometimes used to indicate a state of disease in cases of both physical ailment and psychological conditions. A physician practicing pathology is called a pathologist.
Anatomical pathology (Commonwealth) or anatomic pathology (U.S.) is a medical specialty that is concerned with the diagnosis of disease based on the macroscopic, microscopic, biochemical, immunologic and molecular examination of organs and tissues. Over the 20th century, surgical pathology has evolved tremendously: from historical examination of whole bodies (autopsy) to a more modernized practice, centered on the diagnosis and prognosis of cancer to guide treatment decision-making in oncology. Its modern founder was the Italian scientist Giovanni Battista Morgagni from Forlì.
Clinical chemistry is a division in medical laboratory sciences focusing on qualitative tests of important compounds, referred to as analytes or markers, in bodily fluids and tissues using analytical techniques and specialized instruments. This interdisciplinary field includes knowledge from medicine, biology, chemistry, biomedical engineering, informatics, and an applied form of biochemistry.
A pharmacist, also known as a chemist in Commonwealth English, is a healthcare professional who is knowledgeable about preparation, mechanism of action, clinical usage and legislation of medications in order to dispense them safely to the public and to provide consultancy services. A pharmacist also often serves as a primary care provider in the community and offers services, such as health screenings and immunizations.
Michael Smith was a British-born Canadian biochemist and businessman. He shared the 1993 Nobel Prize in Chemistry with Kary Mullis for his work in developing site-directed mutagenesis. Following a PhD in 1956 from the University of Manchester, he undertook postdoctoral research with Har Gobind Khorana at the British Columbia Research Council in Vancouver, British Columbia, Canada. Subsequently, Smith worked at the Fisheries Research Board of Canada Laboratory in Vancouver before being appointed a professor of biochemistry in the UBC Faculty of Medicine in 1966. Smith's career included roles as the founding director of the UBC Biotechnology Laboratory and the founding scientific leader of the Protein Engineering Network of Centres of Excellence (PENCE). In 1996 he was named Peter Wall Distinguished Professor of Biotechnology. Subsequently, he became the founding director of the Genome Sequencing Centre at the BC Cancer Research Centre.
Pharmacy is the science and practice of discovering, producing, preparing, dispensing, reviewing and monitoring medications, aiming to ensure the safe, effective, and affordable use of medicines. It is a miscellaneous science as it links health sciences with pharmaceutical sciences and natural sciences. The professional practice is becoming more clinically oriented as most of the drugs are now manufactured by pharmaceutical industries. Based on the setting, pharmacy practice is either classified as community or institutional pharmacy. Providing direct patient care in the community of institutional pharmacies is considered clinical pharmacy.
A medical specialty is a branch of medical practice that is focused on a defined group of patients, diseases, skills, or philosophy. Examples include those branches of medicine that deal exclusively with children (paediatrics), cancer (oncology), laboratory medicine (pathology), or primary care. After completing medical school or other basic training, physicians or surgeons and other clinicians usually further their medical education in a specific specialty of medicine by completing a multiple-year residency to become a specialist.
Clinical pathology is a medical specialty that is concerned with the diagnosis of disease based on the laboratory analysis of bodily fluids, such as blood, urine, and tissue homogenates or extracts using the tools of chemistry, microbiology, hematology, molecular pathology, and Immunohaematology. This specialty requires a medical residency.
A Medical Laboratory Scientist (MLS) or Clinical Laboratory Scientist (CLS) or Medical Technologist (MT) performs diagnostic testing of blood and body fluids in clinical laboratories. The scope of a medical laboratory scientist's work begins with the receipt of patient or client specimens and finishes with the delivery of test results to physicians and other healthcare providers. The utility of clinical diagnostic testing relies squarely on the validity of test methodology. To this end, much of the work done by medical laboratory scientists involves ensuring specimen quality, interpreting test results, data-logging, testing control products, performing calibration, maintenance, validation, and troubleshooting of instrumentation as well as performing statistical analyses to verify the accuracy and repeatability of testing. Medical laboratory scientists may also assist healthcare providers with test selection and specimen collection and are responsible for prompt verbal delivery of critical lab results. Medical Laboratory Scientists in healthcare settings also play an important role in clinical diagnosis. An estimated 70% of medical decisions are based on laboratory test results and MLS contributions affect 95% of a health system's costs.
The International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) is a global professional association that promotes the fields of clinical chemistry and laboratory medicine. It was established in Paris in 1952 as the International Association of Clinical Biochemists to organize the various national societies of these fields and is based in Milan, Italy.
A clinical coder—also known as clinical coding officer, diagnostic coder, medical coder, or nosologist—is a health information professional whose main duties are to analyse clinical statements and assign standardized codes using a classification system. The health data produced are an integral part of health information management, and are used by local and national governments, private healthcare organizations and international agencies for various purposes, including medical and health services research, epidemiological studies, health resource allocation, case mix management, public health programming, medical billing, and public education.
The American Board of Nuclear Medicine (ABNM) certifies physicians as specialists in the practice of nuclear medicine. Diplomates of the ABNM are called nuclear medicine physicians. The ABNM is one of the 24 member boards of the American Board of Medical Specialties (ABMS).
Nuclear medicine physicians, also called nuclear radiologists or simply nucleologists, are medical specialists that use tracers, usually radiopharmaceuticals, for diagnosis and therapy. Nuclear medicine procedures are the major clinical applications of molecular imaging and molecular therapy. In the United States, nuclear medicine physicians are certified by the American Board of Nuclear Medicine and the American Osteopathic Board of Nuclear Medicine.
Helen Murray Free was an American chemist and educator. She is most known for revolutionizing many in vitro self-testing systems for diabetes and other diseases while working at Miles Laboratories. The tests are still marketed today with blood tests as Ascensia Diabetes Care, and urine tests under Siemens Healthineers. The pioneering dip-and-read strips allowed for testing to be more convenient and efficient and reduced doctors’ and patients’ dependence on laboratories for results as well as the cost of testing.
Edison T. Liu is an American chemist who is the former president and CEO of The Jackson Laboratory, and the former director of its NCI-designated Cancer Center (2012-2021).
