Department of Clinical Pathology
Clinical pathology covers a wide range of laboratory functions and is concerned with the diagnosis, treatment, and
prevention of disease. Clinical pathologists are healthcare providers with special training who often direct all of the
special divisions of the lab. This may include the blood bank, clinical chemistry and biology, toxicology, hematology,
immunology and serology, and microbiology. Clinical pathology also involves maintenance of information systems, research,
and quality control.
What does a clinical pathology do?
A clinical pathologist looks at blood, urine, and other body fluid specimens under a microscope, or with other diagnostic
tools, to observe levels of certain chemicals and/or other substances in the body. A diagnosis or determination to conduct
further study is then made based on the test results. Specimens for exam can include any of the following:
Types of specimens used in Clinical Pathology Investigations
Blood is used in many tests. Blood can either be examined as a "whole," as plasma (the fluid left when red and white blood cells
are removed), or as serum (a clear fluid that separates from blood when it clots).Blood is usually drawn with a needle from a vein,
usually in the forearm. (This is also called venipuncture). Sometimes, the tip of the finger is pricked and then squeezed to
draw blood (called a finger stick).
Urine is also used for a wide range of tests. Urine specimens can be obtained by:
Random method. The patient urinates in a cup.
Clean catch specimen. The outer genital area has been cleaned before urinating in a cup.
Sterile urine test. This needs catheterization (a tube is put into the urethra and goes to the bladder to obtain urine).
Sometimes, a healthcare provider will need the patient to do a timed test to measure substances excreted into the urine over several hours.
Automated Urine Chemistry
Automated Urine Chemistry Analyzer is a fully automated, benchtop instrument designed for high-volume urine testing,
using Siemens' proven technology in dry-pad urine chemistry analysis.
