Defining the Practice of the Medical Technology Profession

Expected Learning Outcomes

  • Upon completion of the lecture the learner should be able to:
    • Discuss the nature of the practice of the Medical Technology profession in relation to the detection of causes and diagnosis of diseases.
    • Differentiate Medical Technologists from other laboratory personnel.
    • Enumerate and explain the opportunities and challenges of the profession.

Science and Technology: Foundational Concepts

  • Science
    • Primarily investigates the natural world and the inter-relationships among the biological, psychological, and social spheres.
  • Technology
    • The concrete application of scientific knowledge for societal benefit.
    • May refer to:
    1. A physical artifact, machine, or instrument.
    2. An activity or means to accomplish a goal.
    3. Systematized scientific knowledge used for practical purposes.
  • Medical Technology is an integration of both science and technology and therefore inherits the rigor of scientific inquiry and the practicality of technological application.

Defining Medical Technology Practice in the Philippines

Legal Foundations

  • Medical Technology Act of 1969 – RA\,5527
  • RA\,6132 (amending sections of RA\,5527)
  • Presidential Decrees: PD\,498 and PD\,1534

Statutory Definition (Section 2 of RA\,5527)

  • The practice of Medical Technology includes, but is not limited to:
    • Examination of tissues, secretions, excretions, and body fluids using electronic, chemical, microscopic, bacteriologic, hematologic, serologic, immunologic, nuclear, and other procedures (manual or automated).
    • Blood-banking procedures.
    • Parasitologic, mycologic, and microbiologic procedures.
    • Histopathology and cytotechnology (a Medical Laboratory Technician may perform histopathologic techniques under supervision).
    • Clinical research on human subjects requiring MT knowledge/procedures.
    • Preparation and standardization of reagents, standards, and stains exclusively for in-house laboratory use.
    • Clinical laboratory quality control.
    • Collection and preservation of specimens.
  • Exemptions: Individuals already licensed in another profession whose incidental acts overlap with MT practice are not covered by the last four bulleted items.
  • Key requirements:
    • Only licensed individuals may legally practice.
    • Practice must conform to the profession’s Code of Ethics.

Code of Ethics for Medical Technologists (Dr. Nardito Moraleta – Original Version)

  • Acceptance of professional responsibilities and ideals.
  • Awareness that physicians rely on laboratory data for diagnosis and therapy; thus, errors may cost patient health or life.
  • Commitment to absolute reliability, accuracy, fairness, and honesty in every procedure.
  • Emphasis on mutual understanding and cooperation with other medical and paramedical workers.
  • Personal integrity, development of professional virtues, and prioritization of service over self-interest.
  • Constructive criticism only; knowledge must never be used for selfish ends.
  • Confidentiality of all patient information; results disclosed solely to the attending physician.
  • Refraining from diagnosis or therapeutic advice beyond the issued report.
  • Advocacy of equal opportunities and respect for human rights.

Characteristics of the Medical Technology Profession

  • Sensuous and flexible
  • Preferential health-oriented service
  • Adventurous and self-fulfilling
  • Informative and research-oriented
  • Health-promoting and educative
  • Medical mediator, paradigmatic, self-conscious, and oriented toward perfectibility

Roles and Responsibilities of Medical Technologists

B. Perform Special Procedures

  • Proficient in molecular and nuclear diagnostics.
  • Operate advanced diagnostic equipment (e.g., PCR, flow cytometry, gamma counters).

C. Ensure Accuracy and Precision of Results

  • Constant verification of both processes and outputs.
  • Accuracy + Precision ⇒ correct interpretation by physicians ⇒ proper medication and treatment.

D. Be Honest in Practice

  • Adherence to the MT Code of Ethics.
  • Integrity throughout all phases of testing.

E. Ensure Timely Delivery of Results

  • Recognition of result urgency.
  • Responsiveness to patient needs.

F. Demonstrate Professionalism

  • Familiarity with all governing laws: RA\,5527 (MT Act), RA\,4688 (Clinical Lab Law), RA\,1517 (Blood Banking Act), RA\,7719 (National Blood Services Act).
  • Avoiding exploitation or over-stepping professional boundaries.

G. Uphold Confidentiality

  • Protection of patient health information unless explicit consent is given.

H. Collaborate with Other Health-Care Professionals

  • Essential for a well-functioning multidisciplinary team.
  • Correct diagnosis and management rely on seamless laboratory–clinical interaction.

I. Conduct Research

  • Continuous skills upgrading through investigative work and evidence generation.

J. Involvement in Health-Promotion Programs

  • Participation in community outreach:
    • Hygiene education, sanitation, waste segregation, disease prevention.
    • Implementation of planned health campaigns.
    • Offering free laboratory testing and integrating results into broader public-health initiatives.

Distinction from Other Laboratory Personnel

Pathologist (per RA\,5527)

  • A licensed physician with specialized training in laboratory medicine and gross & microscopic tissue examination.

Medical Laboratory Technician (Med Lab Tech)

  • Certified and registered with the Board of Medical Technology to assist MTs and pathologists.
  • Alternative qualifications:
    • Failed MT board but obtained at least 70\%.
    • Government employment requires civil-service eligibility not lower than second grade.
    • Passed the civil-service exam for Med Techs (March 21,\,1969).
    • Completed a 2-year college course plus at least 1 year laboratory experience (with specific substitution clauses up to 10 years’ experience).

Phlebotomist

  • Trained in venipuncture for tests or blood donation.
