Clinical Laboratory Organization, Classifications, and Health Service Demand
Clinical Laboratory Organizational Structure
- Hierarchy of Roles: Hospital Administrator → Laboratory Director (Department Head) → Chief of Different Sections (Associate Pathologist) → Chief Medical Technologist / Laboratory Manager → Assistant Chief Medical Technologist → Section Heads → Staff Medical Technologists, Laboratory Technicians, Laboratory Nurses, Laboratory Aides, and Clerks.
- Laboratory Director: A Pathologist (Medical Doctor, Doctoral Scientist, or Doctor of Osteopathy) who holds ultimate responsibility for all laboratory operations.
- Laboratory Manager: Professionally trained in laboratory sciences with management background; oversees daily operations, sets personnel standards, manages quality control programs, and monitors procedural manuals.
- General Supervisor / Section Head: Manages work quantity and quality within specific sections (e.g., Hematology, Microbiology, Clinical Chemistry, Blood Bank, Immunology/Serology, Clinical Microscopy, Histopath) and evaluates employee performance.
- Testing Personnel / Bench Technologist: Staff Medical Technologists who directly perform laboratory analyses.
- Support Personnel:
- Laboratory Technician: Assists Medical Technologists in executing assays.
- Phlebotomist / Laboratory Nurse: Executes blood extractions.
- Laboratory Aide: Cleans and maintains laboratory equipment.
Qualifications and Personal Attributes of Personnel
- Medical Technologist (MT) / Clinical Laboratory Scientist (CLS) Qualifications:
- Baccalaureate degree from an accredited college or university.
- Completion of clinical training in an accredited Medical Technology program.
- Successful passage of the National Examination (Medical Technology Board Licensure Examination).
- Desirable Personal Qualities: Dedication, cooperation, neatness, caring attitude, physical stamina, good eyesight, normal color vision, manual dexterity, intellectual aptitude for biological sciences, and strong communication skills.
Professional Ethics and Confidentiality
- Governing Bodies: American Association of Clinical Laboratory Science (ASCLS; formerly American Society for Medical Technology / ASMT) internationally; Professional Regulation Commission Ethics Committee and PAMET Ethics Committee locally.
- Confidentiality Protocol:
- Patient data is restricted strictly to healthcare employees directly managing the case on a "need to know" basis.
- Test results are reported solely to ordering physicians or designated personnel, never discussed directly with patients or their relatives.
- Standards of Conduct: Demands courtesy, patient consideration, analytical accuracy, and adherence to optimal techniques.
Classification of Clinical Laboratories
- By Ownership: Government or Private.
- By Institutional Character: Institution-based (e.g., hospital, medical clinic, birthing home, psychiatric facility) or Freestanding.
- By Function:
- Clinical Pathology: Clinical Chemistry, Hematology, Immunohematology, Microbiology, Immunology, Clinical Microscopy, Endocrinology, Molecular Biology, Cytogenetics, Toxicology, and Therapeutic Drug Monitoring.
- Anatomic Pathology: Surgical Pathology, Immunohistopathology, Cytology, Autopsy, Forensic Pathology, and Molecular Pathology.
- By Service Capacity (General Clinical Laboratories):
- Primary Category: Routine hematology (hemoglobin, RBC count, hematocrit, WBC count, leukocyte differential count), qualitative platelet determination, routine urinalysis, routine fecalysis, and hospital-based blood typing.
- Secondary Category: Primary capabilities plus routine clinical chemistry (blood glucose, BUN, URCA, creatinine, total cholesterol), quantitative platelet determination, hospital-based crossmatching, Gram staining, and KOH mounts.
- Tertiary Category: Secondary capabilities plus special chemistry, special hematology (coagulation procedures), immunology, and microbiology (culture and sensitivity for aerobic and anaerobic organisms).
Specialized Clinical Laboratory Facilities
- Special Clinical Laboratories: Offer highly specialized services not standard in general facilities, such as fertility laboratories and molecular/cellular biology units.
- National Reference Laboratories (NRL): Government hospital laboratories designated by the Department of Health (DOH) to perform confirmatory testing, disease surveillance, research, training, kit/reagent evaluation, and external quality assessment programs.
- Satellite & Mobile Facilities:
- Satellite Testing Sites: Perform lab examinations outside the primary facility under its administrative control.
- Mobile Clinical Laboratory: Transportable units moving between testing locations.
- Temporary Locations: Allowed solely for specimen collection within a 100km radius of the main clinical laboratory.
Factors Influencing Health Service Demand
- Income: Higher family income increases actual service usage due to affordability, but also allows investment in preventive care that lowers overall curative need (double effect of income).
- Price: Cost negatively impacts healthcare demand; Heller noted that private healthcare pricing directly influences choices regarding public facility usage.
- Health Insurance: Reduces out-of-pocket costs and enhances financial capability, increasing utilization and healthcare expenditure.
- Demographics & Family Size:
- Age: Presence of children and elderly individuals increases illness frequency and healthcare demand.
- Family Size: Larger family units experience a higher overall frequency of illness.
- Education: Higher education improves early symptom recognition and shifts expenditure toward preventive care over curative services.
- Knowledge, Beliefs, & Need: Self-perceived health need prompts market entry, while physician assessment determines true clinical necessity.
- Facility Distance: Greater geographic distance to a facility significantly reduces user visits.
