Study Notes

Definition of a Medical Laboratory

  • A medical laboratory is a place equipped with various biomedical instruments and chemicals for performing different lab diagnostic activities using biological specimens.
  • It is also called clinical laboratory science.

History of Medical Laboratory Science

  • Medical laboratory sciences have existed for almost 100 years as part of healthcare.
  • Initially, laboratory physicians (pathologists) and/or academic researchers trained individuals to perform procedures under their guidance.
  • Development in medical laboratory science led to the need for well-defined and more academically organized programs.

Development in Medical Laboratory

  • In the 1950s and 1960s, there was an explosion of knowledge in biological and clinical sciences, leading to the development of automation and more sophisticated laboratory techniques.
  • This led to the need for professionally organized medical laboratory science programs, resulting in bachelor's, master's, and doctoral degree programs.

Laboratory Risks Groups

  • Risk groups are classifications that describe the relative hazard posed by infectious agents or toxins in the laboratory.
  • Considerations used in a biological risk assessment include the ability of an infectious agent or toxin to cause disease, the way in which the infectious agent or toxin causes disease, and the safety equipment and design elements present in the laboratory.

Classification of Laboratories

  • WHO classifies laboratories into 3 levels based on risk levels:
    • Risk Group I: Low individual and low community risk.
    • Risk Group II: Moderate individual risk and limited community risk.
    • Risk Group III: High individual risk and low community risk.
    • Risk Group IV: High individual and community risk.

Structure of Laboratory Services

  • A medical laboratory service must be integrated with the health care system, functioning as a network that is accessible and provides needed services to the community and population at large.

Types of Laboratories

  • Basic Laboratory (Level 1 and 2): Adequate for work at PHC and hospital diagnostic labs, suitable for work with organisms in Risk Group 1 and 2.
  • Containment Laboratory (Level 3): More advanced, used for work with infectious organisms, with specific design and safety features.
  • Maximum Containment Laboratory (Level 4): Intended for work with viruses, with the strictest safety precautions.

Functions of Medical Laboratory

  • Providing quality health care services
  • Achieving efficiency and cost-effectiveness in healthcare systems
  • Achieving good health planning and management in healthcare systems

Role of Laboratory in Providing Quality Health Care

  • Increases accuracy of disease diagnosis
  • Essential in screening for ill health and assessing response to treatment
  • Provides therapeutic guidance for drug use and monitoring side effects

Functions and Use of Different Medical Laboratory Departments/Units

  • Hematology: deals with examination of blood constituents
  • Clinical Chemistry: deals with measurement of biochemical changes in serum and body fluids
  • Immunohematology: deals with blood banking and transfusion medicine
  • Medical Microbiology: deals with microorganisms of medical importance, including bacteriology, virology, mycology, parasitology, and immunology
  • Molecular Biology: seeks to understand the molecular basis of life

Role of Medical Laboratory Personnel

  • Medical laboratory assistants (MLAs) are responsible for sampling, testing, measuring, recording, and analyzing specimens in cooperation with the rest of the laboratory professional team.
