    Study Notes

    Transporting Patient Specimen

    • A transport container must be watertight, made of glass, metal, or plastic with a positive (screw-on) cap, and follow DOT and IATA rules for suspected infectious specimen
    • Understanding the transmission of microorganisms is necessary to prevent infection
    • Sharps hazards, chemical hazards, and radioactive waste must be considered in the laboratory

    Safety in the Laboratory

    • The laboratory contains a wide variety of safety hazards, including biohazardous waste, radioactive materials, and carcinogenic chemicals
    • Laboratorians must learn what hazards exist and take precautions, applying basic safety rules and common sense
    • Personal Protective Equipment (PPE) is necessary when handling hazardous materials
    • Hand contact is the number one method of infection transmission, and hands should be washed frequently, especially before patient contact, after removing gloves, and before leaving the working area

    Handwashing

    • Handwashing is the most powerful technique to break the infection cycle
    • Water must be continuous during washing, and hands must be wet with warm water
    • Anti-microbial soap must be applied, and hands must be rubbed to form a lather, creating friction to loosen debris
    • Hands must be thoroughly cleaned, including between fingers, under fingernails, and up to the wrist, for at least 20 seconds

    Agglutination Reaction

    • Agglutination is a type of precipitation reaction that occurs between antibodies and soluble antigens
    • Steps in agglutination reaction include lattice formation and coagglutination
    • Types of agglutination reaction include direct, passive, reverse-passive, and agglutination inhibition

    Chain of Infection

    • The chain of infection is a cycle that involves source, mode of transmission, and susceptible host
    • Breaking the chain of infection requires a continuous link between these three elements
    • Breaking the chain of infection can be achieved by handwashing, biohazardous waste disposal, and proper specimen bagging
