CHAPTER THREE: LABORATORY ORGANIZATION

Learning Objectives

• Organize and administer the laboratory for quality service delivery.

• Explain structure, staffing, and functions of various health laboratories.

• Describe facilities and principles of safe laboratory design.

3.1 Introduction

• Definition of organization: a system that promotes cooperation and efficiency.

• Key focus: arrangements allowing collaboration towards common objectives.

• Importance of leadership, experience, and enthusiasm for effective organization.

• Two components of laboratory organization:

  • Overall management by the director.

  • Organization of units by section heads.

Organizational Responsibilities

• Director's Role:

  • Define goals and set policies.

  • Analyze general problems and devise solutions.

  • Fund laboratories and coordinate section work.

  • Set personnel policies and interpret hospital board policies.

• Section Head's Role:

  • Operate within director's policies.

  • Utilize staff skills effectively.

  • Supervise space, equipment, and supply usage.

  • Streamline workflows and manage specimen processing.

3.2 Organization of Health Laboratory Service in Ethiopia

• Historical Context:

  • Established by Italians during WWII.

  • Post-independence taken over by British and later French teams.

  • Creation of Central Laboratory and Research Institute (CLRI).

• Current Laboratory Landscape:

  • Numerous laboratories, from Ethiopian Health and Nutrition Research Institute (EHNRI) to local health center labs.

• Types of Laboratories in Ethiopia:

  • National Research Institute of Health

  • Regional Health Research Institutions

  • Public Health Laboratories

  • Hospital Laboratories

  • Health Center Laboratories

3.3 Structure and Functions of Laboratory Services

3.3.1 Community-Based Primary Health Care Laboratory

• Located at community levels, essential for health care access.

• Functions include:

  • Investigate and control diseases.

  • Health education support.

  • Screen for anemia, malaria, and other prevalent conditions.

Staffing

• Typically staffed by junior lab technicians and community health workers.

• Responsibilities include specimen examination and community health participation.

3.3.2 District Hospital Laboratory

• Role:

  • Supervising community-based laboratories and performing various tests.

Staffing

• Staff includes qualified senior lab technicians and assistants.

Functions

• Carry out essential tests for public health and medical activities.

• Support community lab activities and participate in quality assurance.

3.3.3 Regional Hospital Laboratory

• Role:

  • Assist district labs, conduct specialized tests for regional hospitals.

Staffing

• Comprises laboratory officers, technologists, and lab aides.

Functions

• Perform tests as per medical needs, operate transfusion centers, and investigate public health issues.

3.3.4 Central Public Health Laboratory

• Responsibilities:

  • Plan and coordinate national laboratory services.

  • Ensure reliability and training of laboratory personnel.

Staffing

• Includes a director, research scientists, senior technologists, safety officers, etc.

Functions

• Formulate professional codes, conduct advanced tests, and perform national health research.

  • Organize blood transfusion services and collaborate with international organizations.

3.4 Safe Laboratory Design

3.4.1 The Laboratory Environment - Facilities

• Essential needs for a lab: building, power, water supply.

• Importance of proper lab design for operation efficiency.

3.4.2 Standard Design for Laboratories

• Lack of standard designs leads to inefficiencies.

• Considerations for lab design:

  1. Workload and types of tests performed.

  2. Staffing requirements.

  3. Equipment and furniture needs.

  4. Basic utilities provision.

Design Elements

• Walls: Permanent external; temporary internal for easy replacement.

• Ceilings: Easy to clean; secure against contaminants.

• Floors: Durable, cleanable materials resistant to chemicals.

• Doors: Wide for equipment movement; easy access.

• Windows: Provide natural light; designed to minimize drafts.

Air Handling and Environmental Controls

• Use natural ventilation to improve air quality.

• Installation of shading and thermal barriers to control temperature.

Sample Ideal Laboratory Features

• Main working room (4x5 m), washing room (2x2 m), and storerooms.

• Continuous running water supply; proper electrical setup for equipment.

• Refrigeration for specimens; separate toilets for patients.

• Ensure cleanliness and proper disposal in restrooms.
