clinical microbiologist major function is to isolate and identify  microbes from clinical specimens rapidly clinical specimen portion or quantity of human material that is  tested, examined, or studied to determine the  presence or absence of specific microbes 2 Overview of the Clinical  Microbiology Laboratory

numerous methods used; choice of  method depends on specimen specimen should represent the diseased  area quantity should be adequate collection to avoid contamination proper container, promptly sent to  laboratory obtain specimen before antimicrobial  treatment 3 Specimen Collection

e.g., workers can limit their contact with  microbes by not eating or smoking in lab and  by preventing injuries caused by sharp  objects e.g., coverings such as lab coats and  bandages should be used e.g., workers should know how to use  emergency eye wash and shower stations e.g., work space should be disinfected e.g., hands should be washed thoroughly  after any exposure and before leaving lab 6 Standard Microbiological  Practices…
