Histopath Extra Large Test

What is this test?

The main use of histopathology is in clinical medicine where it typically involves the examination of a biopsy (i.e. a surgically removed sample or specimen taken from a patient for the purposes of detailed study) by a specialist physician called a pathologist. Depending on his or her specialist training and main area of work, the pathologist may be more accurately referred to as a histopathologist because medical specialists who study and interpret diseased tissues in microscopic detail are histopathologists. However, in the cases of some pathologists, examination of diseased tissues in microscopic detail may only be a relatively minor part of their overall professional responsibilities so the term 'histopathologist' may not always be used. A pathologist or histopathologist studies specimens of cells and tissue after a sample has been removed from the patient, processed using special histological techniques - some of which are summarised on the page about how to prepare histology slides, and carefully prepared histological sections of the specimen have been placed on slides and stained using histology stains ready for observation using a microscope. Either a light microscope or an electron microscope may be used to examine histology slides. Histopathologists are medical specialists who have broad knowledge and understanding of the pathological and clinical aspects of disease. They work with a wide range of patients and medical conditions as well as with many other medical professionals who have expertise in associated disciplines, as well as with an ever-increasing range and complexity of technologies including some medical imaging equipment such as electron microscopes. Sub-specialties associated with histopathology include cytopathology, forensic pathology, neuropathology and paediatric pathology. Although clinical medicine (which is a term that refers to the context of diagnosing, treating, or trying to treat and advise a patient) is a very important application of histopathology, histopathology is not only used in clinical medicine. Diseased cells and biological tissues are also studied in microscopic detail for other reasons, such as to: investigate crimes e.g. look for causes of injury or death such as evidence of tissue damage by poisons, drugs or possibly deliberately targeted biological pathogens - Forensic Pathology or Forensic Histopathology. investigate historical artefacts containing biological tissue in sufficiently good condition to learn about the health of long-deceased individuals - which can involve various types of histology and histopathology, e.g. bone histology, dental histology and so on. This is similar to the study of ancient diseases (an area of study known as 'paleopathology', sometimes spelt 'palaeopathology') using histological techniques - Histology in Palaeopathology, or Histopalaeopathology.
