Examination of cells in body fluids was historically performed using a hemocytometer, a chamber designed for counting cells microscopically. [11] This technique was limited by poor discrimination between cell types (cells could only be classified as mononuclear or polymorphonuclear) and the low number of cells present in unconcentrated body fluids.
The interpretation of urinalysis takes into account the results of physical, chemical and microscopic examination and the person's overall condition. Urine test results should always be interpreted using the reference range provided by the laboratory that performed the test, or using information provided by the test strip/device manufacturer ...
Blood gas analyzer: used to analyze and quantify the amount of various toxic gases within blood like Carbon monoxide: Electroencephalography : to read and trace the electrical activity of the brain; video link: Polymerase chain reaction (PCR) apparatus: video link: Ophthalmoscope: to note the intra-ocular signs or effects of toxins: Endoscope
Cytopathology is a sub-discipline of anatomical pathology concerned with the microscopic examination of whole, individual cells obtained from exfoliation or fine-needle aspirates. Cytopathologists are trained to perform fine-needle aspirates of superficially located organs, masses, or cysts and are often able to render an immediate diagnosis in ...
Experimental pathology, also known as investigative pathology, is the scientific study of disease processes through the microscopic or molecular examination of organs, tissues, cells, or body fluids from diseased organisms. It is closely related, both historically and in modern academic settings, to the medical field of pathology.
Pathologists may review samples such as pleural, peritoneal, synovial, or pericardial fluids to characterize them as "normal", tumoral, inflammatory, or even infectious. Microscopic examination can also determine the causal infectious agent – often a bacterium, mould, yeast, parasite, or (rarely) virus.
Gross examination of a kidney (right of image) with a renal oncocytoma (left of image).. Gross processing, "grossing" or "gross pathology" is the process by which pathology specimens undergo examination with the bare eye to obtain diagnostic information, as well as cutting and tissue sampling in order to prepare material for subsequent microscopic examination.
Renal biopsy (also kidney biopsy) is a medical procedure in which a small piece of kidney is removed from the body for examination, usually under a microscope. [1] Microscopic examination of the tissue can provide information needed to diagnose, monitor or treat problems of the kidney.
