diagnosis of disease
- concluded that the appearance of bubbles, blood, and pus indicate kidney disease and chronic
illnesses

Defining the Practice of Medical Technology/Clinical Laboratory Science Profession
Nature of Medical Technology
• Science of medical technology has evolved because of the development of modern equipment and new
procedures aimed at helping in the diagnosis and treatment of diseases
• Technology: promotes life and saves life
• In the nature of medical technology, it is important to know the connection between science and
technology.
• Science
- concerned with the study of the natural world and the interrelationship among the biological,
physiological, and even the social world.
- Chemistry, electronics, optics and mechanics: are highly dependent on developments of scientific
discipline to develop a utilizable biotechnology that will aid in the diagnosis of diseases.
• Technology
- Application of science in ways that are considered beneficial to society
Defined in 3 ways
- As a physical artefact, machine, or instrument
- As an activity or a means to accomplish a goal
- As knowledge
Rogers (1983)
Asserts that “technology is a design for instrumental action that reduces the uncertainty in the
cause-effect relationships involved in achieving a desired outcome”
- Technology consist of physical elements such as equipment, materials, or products and intangible
elements such as knowledge, skills, procedures, principles, or information base
- An avenue for humans to alter or modify the environment in order to extend their abilities to
create, invent, discover, or innovate to make the world a better place to live in.
• Medical Technology
- Improve the detection, diagnosis, treatment, and monitoring of diseases.
- Its nature is contextual, interdisciplinary, interdependent, and system-based
- Dependent on the application, purpose, environment, and setting in which it is applied.
• Clinical Laboratory Testing
- Crucial role in detection, diagnosis, and treatment of diseases.
- Clinical laboratory scientists perform most of these lab tests and are involved in:
▪ Examination and analysis of body fluids
▪ Tissues
▪ Cells
They look for the presence of
▪ Bacteria
▪ Parasites
▪ Other microorganisms in the body
They analyze the
▪ Chemical contents of fluid
▪ Match blood for transfusions
▪ Test for drug levels in the blood to show patient’s response to specific treatment.
After testing and examining the specimen they analyze the results and relay them to physicians.
ADDITIONAL:
▪ Analyze chemical constituents of fluids
▪ Match blood for transfusion
▪ Microbial culture and sensitivity testing (Microbiology/Parasitology)
▪ Manipulate sophisticated lab equipment
- Clinical laboratory is the place where lab scientists work
- Lumbar puncture
is performed to obtain cerebrospinal fluid CSF
examined by lab scientist
examine protein levels in CSF
MEDICAL TECHNOLOGY PRACTICE DEFINED
• RA 5527 Medical Technology Act of 1969
- The medical technology profession and its practice in the Philippines is governed and define under
the section 2 of this republic act
- as amended by R.A. 6132, P.D. 498, and P.D. 1534, defines the practice of medical technology
(basa sa pdf)
• Practice of medtech
- a medical technologist must first become licensed before he or she is permitted to practice the
profession.
- Practicing medtech without license is punishable by law
- Should be bound by the accepted pledge of oath in accordance with the Code of Ethics of Medical
Technology which states that the Medical Technology professional should accept the
responsibilities inherent to being a professional and shall not engage in illegal activities.
ROLES AND RESPONSIBILITIES OF MEDICAL TECHNOLOGY PROFESSIONALS
• Perform Clinical laboratory Testing
- Must be capable of performing the most basic to the most advanced laboratory tests
- A graduate of BSMT/MLS is expected to show competency in performing routine laboratory tests
including urinalysis and stool examination.
- Should be capable of performing hematologic, microbiologic, serologic, chemical, and other
procedures
- Clinical lab is expected to be fully equipped with resources necessary for performing such
procedures
• Perform Special Procedures
- Operation of advanced diagnostic equipment
- Molecular and nuclear diagnostics
• Ensure Accuracy and Precision of Results
- Should always be conscious of the accuracy and precision of both testing process and its results
• Be Honest in Practice
- Should act according to the Medical Technology profession’s code of ethics and his or her pledge
oath of practice
- To come up with accurate and precise results
• Ensure Timely Delivery of Results
- Must be aware of the urgency on delivering results on time especially in cases that require urgent
treatment
- STAT: immediate action
- Be alert to fully address the needs of patient
• Demonstrate Professionalism
- Perform his or her actions according to professional code of ethics for medical technology
professionals
- Should be aware of laws and regulations governing the practice of medical technology and should
not exploit its function beyond boundaries.
- R.A. 5527 or the Philippine Medical Technology Act of 1969
- R.A. 4688 Clinical Laboratory Act of 1966
- R.A 1517 Blood Banking Acts of 1956 and 1995 (RA 7719)
- Philippine Association of Schools of Medical Technology and Public Health (PASMETH) and
Philippine Association of Medical Technologists, Inc. (PAMET)
• Uphold Confidentiality
- Keep a patient’s personal health information private unless the patient consent to release the
information
- Patient records are expected to be kept in confidence by the medical technologist
- Protected and made available only when necessary
• Collaborate with Other Health Care Professionals
- REQUIRED to collaborate with other health care practitioners
- Success in health care setting is achieved not because of the availability of highly sophisticated
hospital or laboratory equipment but because of TEAMWORK
- Having one non-collaborative and incompetent member in the team alone ca result in potentially
dire repercussions.
• Conduct Research
- Engage in research activities to update their skills.
- Greatly help in the further development of the field and may be used as future reference for
patient care
• Involvement in Health Promotion Programs
DEFINING THE PRACTICE OF OTHER LABORATORY PERSONNEL
Medical Laboratory Science:
- One of the most important fields of health care delivery system.
- Plays an important role in diagnosis, treatment, and management of disease.
Medical Technology
