**PRINCIPLES OF MEDICAL LABORATORY SCIENCE 1** **HISTORY OF MEDICAL TECHNOLOGY PROFESSION** **[HISTORY OF MEDICAL TECHNOLOGY ON A GLOBAL CONTEXT]** Four stages in the historical development of Medical Technology: 1\. 460 BC 2\. Apothecaries Act of 1815 - Baron Karl Von Humbeldt 3\. Modern onset of the Medical technology in the United States in 1871 4\. Establishment of clinical laboratory and medical technology course in the Philippines **HIPPOCRATES** -- regarded as the founder of scientific medicine -- determined the correlation between anatomical and chemical laboratory findings and the causes of diseases. -- adopted the triad of regimen in treating diseases and infection with the use of **drugs, surgery, and bloodletting.** **VIVIAN HERRICK** -- determined that intestinal parasitic infection was caused by Ascaris lumbricoides and the Taenia species. -- This was published in a book by **Ebers Papyrus** which describes the treatment of hookworm disease and infection transmissible in humans. **ANENZOA** **--** an Arabian physician, also proved that the etiological agent of skin diseases, such as scabies, are parasites. **Medieval period (1098-1438) --** Urinalysis **ANNA FAGELSON (14th Century)** -- confirmed the beginnings of medical technology when she correlated the cause of death of **Alexander Gillani**, a laboratory worker in the University of Bologna, to laboratory-acquired infection. **ANTON VAN LEEUWENHOEK (17th century)** -- invented the microscope -- describe the appearance of red blood cells, and differentiated bacteria based on their shape **[MEDICAL TECHNOLOGY IN THE 18TH]** **[CENTURY]** - - **RUDOLF VIRCHOW (between 1821 -- 1902)** -- recognized as the father of microscopic pathology. -- first scientist/physician of the time who emphasized the study of the manifestation of diseases and infections, which are visible at the cellular level by means of a microscope. **DR. CALVIN ELLIS** -- first to utilize the microscope in examining specimens at the Massachusetts General Hospital. **DR. WILLIAM OCCAM** **--** used laboratory findings as preliminary evidence in diagnosing and evaluating a patient\'s disease. **APOTHECARIES ACT OF 1815** -- initiated by Baron Karl Von Humbeldt who formerly used laboratory findings in the treatment of diseases and infection. -- intervened and paved the way for an uphaul of medical treatment based on laboratory findings. -- The Act introduced compulsory apprenticeship and formal qualifications for apothecaries (in modern terms, general practitioners) under the license of the Society of Apothecaries. **[HISTORY OF MEDICAL TECHNOLOGY IN THE UNITED STATES]** In the United States, medical education underwent much needed reforms. **DR. WILLIAM H. WELCH** -- In 1885, Dr. Welch became the first professor of Pathology at John Hopkins University -- The first clinical laboratory was opened in 1896 at the John Hopkins Hospital by Dr. William Osler. -- A clinical laboratory was also opened at the University of Pennsylvania in 1896. (William Pepper Laboratory) **DR. JAMES C. TODD** **--** Wrote "A Manual of Clinical Diagnosis" -- Retitled "Clinical Diagnosis by Laboratory Methods" in the 19th edition **1900**: **Census** -- 100 technicians, all male were employed in the United states **1915** **--** The state legislature of Pennsylvania enacted a law requiring all hospitals and institutions to have an adequate laboratory and to employ a full-time laboratory technician **1920** **--** Increased to 3,500 **1922** **--** 3035 hospitals had clinical laboratories **WORLD WAR I** **--** Was an important factor in the growth of the clinical laboratory and produced a great demand for technicians **UNIVERSITY OF MINNESOTA** **--** Where one of the first schools for training workers was established -- A course bulletin was entitled "Courses in Medical Technology for Clinical and Laboratory Technicians" (1922) **1921** **--** The Denver Society of Clinical Pathologists was organized **1923** **--** University of Minnesota was the first to offer level program **WORLD WAR II** **--** The use of blood increased and the "close system" of blood collection was widely adopted -- Laboratory medicine certainly moved into an era of sophistication **[HISTORY OF MEDICAL TECHNOLOGY IN THE ]** **[PHILIPPINES]** **MEDICAL TECHNOLOGY IN THE PHILIPPINES POST-WORLD WAR II** - **FEBRUARY 1944** -- it provided one year of training to high school graduates to work as laboratory technicians. **JUNE 1945** -- the staff of the 6th US Army left the facility after endorsing the newly established Clinical Laboratory to the National Department of Health. **DR. PIO DE RODA** -- preserved the remains of the laboratory with the help of **Dr. Mariano Icasiano**, the first City Health Officer of Manila. **OCTOBER 1, 1945** -- the preserved laboratory was formally re-established by **Dr. Pio de** **Roda** with the help of **Dr. Prudencio Sta.Ana.** **1954** -- **Dr. Pio de Roda** instructed **Dr. Sta. Ana** to prepare a syllabus for training medical technicians. -- Together with **Dr. Tirso Briones**, they conducted a six month training course with certification. **MANILA SANITARIUM HOSPITAL** and **PHILIPPINE UNION COLLEGE** -- offered a course in medical technology. **DR. WILLA HILGERT HEDRICK** -- founder of medical technology education in the Philippines **DR. REUBEN MANALAYSAY** -- president of the Philippine Union College **REV. WARREN** -- president of the North Philippine Mission of the Seventh Day Adventist and director of the Bureau of Education, established the first Medical Technology School in the Philippines.
