1.1 Medical diagnostics lab

Often referred to as simply a medical or clinical laboratory, the medical diagnostics lab performs tests on clinical specimens in order to get information about the health of a patient as pertaining to the diagnosis, treatment, and prevention of disease.[1] An additional definition is provided by the Clinical Laboratory Improvement Amendments (CLIA) program, as "a facility that performs testing on materials derived from the human body for the purpose of providing information for the diagnosis, prevention, or treatment of any disease or impairment of, or assessment of the health of, human beings."[2]

The medical laboratory at a basic level, whether chemistry or pathology, operates like many other analytical testing laboratories. However, there are a few nuances between the medical laboratory and other analytical laboratories. One of these differences is the need to have a specific unidirectional workflow. This is intended to both minimize the risk of biohazard contamination and to establish assurance that sample cross contamination is minimized.[3][4] Another major difference concerns the regulations governing the management of patient data. This creates a significant challenge not generally experienced by other types of analytical laboratories.

Like other analytical laboratories, regulations, laws, and standard typically drive how vital aspects of how the laboratory operate. However, those regulations, laws, and standards relevant to medical diagnostic and research laboratories provide their own set of challenges.

In the United States, clinical laboratories are primarily regulated by the Department of Health and Human Services. Inside that infrastructure are sub-entities like the Centers for Disease Control and Prevention (CDC) and the Centers for Medicare and Medicaid Services (CMS) to apply standards and regulations through their respective Laboratory Quality Assurance and Standardization Programs, and the Clinical Laboratory Improvement Amendments.[5][6][7] Although generally not as strict as the regulations regarding pharmaceutical and diagnostic manufacturers, they nonetheless establish a significant hurdle to managing the overall operations of the laboratory, from acquiring customers to acquiring samples, as well as testing, reporting results, and handling billing for the completed tests.

Internationally, regulatory bodies vary from country to country. However, organizations like the not-for-profit Clinical and Laboratory Standards Institute (CLSI)[8] and associations like the Research Quality Association (RQA)[9] exist to promote a more global approach to regulations and guidance affecting clinical laboratories. Additionally, a set of Good Clinical Laboratory Practice standards—originally developed in 2002 and since adopted by the World Health Organisation (WHO), non-governmental organisations (NGOs), and research institutions worldwide—provide guidance on implementing laboratory practices that are critical for laboratory operations around the world.[10][11]


1.1.1 Physician office lab

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.[12][13] 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.[13][14] In October 2019, the Centers for Medicare and Medicaid Services (CMS) reported 46% of all CLIA-approved laboratories in the United States (121,265) were physician office laboratories.[15] However, as of 2014, POLs were estimated to be processing only about nine percent of all clinical laboratory tests.[16]

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 2019, 67% of the POLs in the United States were primarily running CLIA waived tests.[17] CLIA test complexity has three levels: high, moderate, and waived.[18] 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.[18] 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 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.[18]

Commonly performed tests include[19]:

  • 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
