[[File:Blood clot.jpg|right|thumb|Pathological view of a blood clot]]Pathology is at the heart of a medical laboratory's operations. In the context of modern medical treatment, the laboratory practice of pathology involves analytical workflow, which falls within the contemporary medical field of "general pathology," and the associated determination of the causes and effects of disease and other medical ailments. General pathology is broadly composed of a number of distinct but inter-related medical specialties that involve the analysis of tissue, cell, and body fluid specimens to better understand the cause, pathogenesis, morphologic changes, and clinical manifestations of a disease.<ref name="KumarRobbins09">{{cite book |title=Robbins and Cotran Pathologic Basis of Disease, Professional Edition |editor=Kumar, V.; Abbas, A.; Fausto, N.; Aster, J. |publisher=Saunders Elsevier |edition=8th |year=2010 |isbn=9781416031215}}</ref> In common medical practice, general pathology is mostly concerned with analyzing known clinical abnormalities that are markers or precursors for both infectious and non-infectious disease and is conducted by experts in one of two major specialties: [[anatomical pathology]] and [[clinical pathology]].

Anatomical (or "anatomic") pathology is a medical specialty of pathology that is concerned with the gross, microscopic, chemical, immunologic, and molecular examination of organs, tissues, and whole bodies (as in autopsy) to determine the presence of disease.

Point-of-care devices such as this rapid syphilis test are commonly used in the POL.

The physician office lab, or POL, is a physician-, partnership-, or group-maintained laboratory that performs medical diagnostic tests or examines specimens in order to diagnose, prevent, and/or treat a disease or impairment in a patient as part of the physician practice.[1][2] The POL shows up in primary care physician offices as well as the offices of specialists like urologists, hematologists, gynecologists, and endocrinologists. In many countries like the United States, the POL is considered a clinical laboratory and is thus regulated by federal, state, and/or local laws affecting such laboratories.[2][3] In October 2021, the Centers for Medicare and Medicaid Services (CMS) reported 41% of all CLIA-approved laboratories in the United States (130,335) were physician office laboratories.[4] However, as of 2014, POLs were estimated to be processing only about nine percent of all clinical laboratory tests.[5]

Testing and reporting at a POL, at least in the U.S., is largely concentrated on the realm of waived CLIA testing. As of October 2021, 68% of the POLs in the United States were primarily running CLIA waived tests.[6] CLIA test complexity has three levels: high, moderate, and waived.[7] Waived tests are simple to perform and have a relatively low risk of an incorrect test result. Moderately complex tests include tests like provider performed microscopy (PPM), which requires the use of a microscope during the office visit. Providers that want to perform PPM tests must be qualified to do so under CLIA regulations.[7] High-complexity tests require the most regulation. These tests are the most complicated and run the highest risk of an inaccurate result, as determined during the Food and Drug Administration (FDA) pre-market approval process. Tests may come from the manufacturer with their complexity level on them, or one can search the FDA database to determine the complexity of the test.[7]

Commonly performed tests include[8]:

  • urine analysis
  • urine pregnancy
  • blood occult
  • glucose blood
  • pathology consultation during surgery
  • crystal identification by microscope
  • sperm identification and analyses
  • bilirubin total
  • blood gasses
  • complete blood count
  • bone marrow smear
  • blood bank services
  • transfusion medicine
