What are precautionary sanctuary contained by the clinical laboratory?
Answers:
Safety in pathology is part and parcel of laboratory quality control. ISO have issued guidelines on safety in medical testing laboratories: ISO 15190. Although this guideline is not compulsory for the purpose of laboratory accreditation, adjectives laboratories are recommended to follow these guidelines.
In this section, various aspects of safety surrounded by a clinical virology laboratory will be looked at. The topics covered are as follows:
Laboratory-Acquired Viral Infections
Classification of Viral Pathogens into Hazard Groups
Classification of laboratories according to use
The Safe Working Environment
Microbiological Safety Cabinets
The Laboratory Worker
Minimizing Equipment and Technique-Related Hazards
Collection, Transport and Receipt of Infectious Materials
Decontamination
Precautions Against Hepatitis and HIV
Infection Hazards of Human Cadavers
Role of Safety Officers
Laboratory-Acquired Viral Infections
The following laboratory-acquired viral infections had been reported;-
Hepatitis A, B, and C - they justification for the majority of known laboratory-acquired infections
Influenza, adeno, and mumps viruses
Polio and coxsackieviruses
Lassa fever (only two reported instances), Marburg, Crimean-Congo, Yellow Fever, Dengue and Hantaviruses
VEE, EEE, Rift Valley disorientation, Chikungunya, Kyasanur Forest Disease, Japanese B encephalitis, West Nile, St Louis, Russian spring-summer, and Louping ill and many other arboviruses
HIV (two cases)
Rabies (two reports)
Infections had occur in widely different kinds of laboratories. Some of the organisms are handled simply in research establishments whilst others are encountered daily within diagnostic and clinical laboratories. The vast majority of reported infections occur in research institutes although a wider population is at risk within a routine diagnostic laboratory. Laboratory-acquired infections are far more likely to occur in untrained workers. In laboratory-acquired infections, the route may not be indistinguishable as the natural route. Routes of infection reported are;-
Oral - eating, drinking, and smoking in the laboratory, mouth pipetting, verbs of microorganisms to mouth by contaminated fingers or articles
Through the skin - injuries by needles, sharp instruments, or glass. Animal bites and scratches. Cuts and scratches.
Through the conjunctiva - splashes of infectious substance into the eye, transfer of microorgansims to eyes by contaminated fingers
Through the lungs - inhalation of airborne microorganisms
The mains sources of laboratory-acquired infections are accidents, animals, clinical specimens, aerosol and work with the agent. The types of accidents involved consist mainly of spillage and splashes, plunger and syringe, sharp objects and broken glass, animal scratch or bites.
