Commits to lifelong learning and teamwork
12. History of a Profession
Professions evolve from informal practice to organized fields with formal education, certifications, regulatory councils, and ethical standards. Advances in science and technology further shape roles and techniques. Today, professions are recognized by specialized knowledge, autonomy, accountability, and commitment to lifelong learning.
13. Professional Recognition
Recognition comes from competence, ethical behavior, public trust, and adherence to standards and regulations.
14. History of Medical Laboratory Science
Medical Laboratory Science has evolved alongside the development of medicine and scientific discovery. In ancient times, simple observations of blood, urine, and other body fluids were used to understand disease. With the invention of the microscope in the 17th century, scientists began to identify cells and microorganisms, marking the foundation of laboratory diagnosis. The 19th and early 20th centuries saw major advances in microbiology, hematology, and clinical chemistry, leading to more accurate disease detection. During the 20th century, Medical Laboratory Science became a formal profession with structured education, specialized laboratory techniques, and quality control systems. Today, it plays a vital role in modern healthcare by supporting diagnosis, treatment, and disease monitoring through advanced technologies such as automation, molecular diagnostics, and laboratory informatics.
15. History of Ethics
The history of ethics in healthcare reflects the changing relationship between society, science, and patient care.
