Chapter 1- Methods Flashcards
Histology
Scientific study of microscopic structures of tissues and organs of the human body.
Another name for Histology
Microscopic anatomy
Histopathology
The branch of histology that includes the microscopic identification and study of diseased tissue.
What is a pathologist?
A medical doctor with specialized training to study medical conditions using human tissue, blood, urine, and other body fluids.
Histotechnology
The field of histology that includes the preparation of tissues for microscopic examination.
Telepathology
A remote pathology practice that sometimes involves sharing virtual slides online in consultation with other pathology specialists.
The job of a pathology Assistant (PA)
A highly trained health professional who works independently under the direction and supervision of a pathologist. They prepare tissue for numerous pathological tests including frozen section, flow cytometry, and immunohistochemical staining.
The job of a Histotechnician (HT)
Prepares and processes tissue samples for routine histologic techniques to be examined under a microscope by a pathologist. The histologic techniques include the following: fixation, processing, embedding, microtomy, and staining of human and animal tissue for evaluation.
The job of a Histotechnologist (HTL)
Performs both routine and complex histologic techniques such as enzyme histochemistry, immunohistochemistry, in-situ hybridization, and immunofluorescence on tissue samples for microscopic examination by a pathologist to diagnose disease.
The job of a Medical Laboratory Technician (MLT)
Collects, processes, and performs routine laboratory tests in blood banking, chemistry, hematology, immunology, microbiology, molecular biology, and/or urinalysis on biological specimens to provide information necessary for the diagnosis and treatment of disease.
The job of a Medical Laboratory Scientist (MLS)
Conducts a full range of laboratory tests, from routine to complex, in blood banking, chemistry, hematology, immunology, microbiology, molecular biology, and/or urinalysis on biological specimens to provide information necessary for the diagnosis and treatment of disease. Problem-solving issues with specimens, testing, and instrumentation. Evaluates, develops, and validates diagnostic testing and instrumentation.
The job of a Diener or Autopsy Assistant
They are highly trained professionals who assist with autopsies and maintain the morgue of the facility.
Biopsy
A procedure to remove a piece of tissue or a sample of cells from the body so that it can be tested in a laboratory.
Purpose of a needle biopsy
A medical procedure that removes tissue or fluid from the body with a needle to help diagnose a medical condition.
Purpose of a fine-needle aspiration
A long, thin needle is inserted into the suspicious area of the body. It is used to draw out fluid and cells for analysis.
Purpose of a core-needle biopsy
A larger needle with a cutting tip used to draw column of tissue out of a suspicious area.
Vacuum-assisted biopsy
A suction device that increases the amount of fluid and cells that is extracted through the needle.
Image-guided biopsy
Combines an imaging procedure (CT scan, MRI, or ultrasound) with a needle biopsy. Allows the health care provider to access suspicious areas that cannot be felt through the skin (on the liver, lung, or prostate).
Endoscopic biopsy
Uses a thin, flexible tube (endoscope) with a light on the end to see structures inside the body. It can be inserted through the mouth, rectum, urinary tract, or small incision in the skin.
Skin biopsy
A procedure that removes cells from the surface of the body. It is often used to diagnose skin conditions like cancer.
Shave biopsy
A skin biopsy in which the health care provider uses a tool similar to a razor to scrape the surface of the skin.
