A Pathology Laboratory is where tests are done on the clinical specimens from which information is found about the diseases or any health issues of the patient to aid in the diagnosis, treatment, and prevention of disease. Clinical Pathology is a medical specialty that focuses on the analysis of bodily fluids to assist in diagnosing diseases or ensuring long-term health. Samples that are used in this type of pathology include blood, urine, blood serum, and other fluids. Most people will have bloodwork or other samples sent for analysis.
