The quality of the test results reported by the laboratory is dependent upon proper patient preparation and collection, handling, and transport of specimens. Test specific specimen requirements are listed in the Test Directory. The suggested specimen volume allows for testing and repeat testing when necessary.
Public Health Menu. Demonstration of pathogenic organisms in the patient specimen is the most definitive test in microbiology. However, failure to demonstrate pathogens in a single specimen is NOT definitive and may only indicate that:. Specimens for culture MUST be collected properly prior to the initiation of antibiotic therapy to insure optimal conditions for the recovery of pathogens.
Appropriate specimen selection, collection, and transportation are critical if laboratory results are used to provide information that establishes a diagnosis and successful treatment. Before antibiotics are administered 2. Acute phase of the infection. Select the correct anatomic site 4. Collect the specimen using the proper technique And supplies with minimal contamination from normal biota normal flora.
The culturing of microorganisms remains the mainstay of laboratory testing for infectious disease, even in an age of rapid and more cost-effective molecular testing. For cultures to be reliable, special attention needs to be paid to the collection, transport, and processing of these specimens. The goal of microbiologic culture is the preservation of viable clinically relevant organisms, specifically ones which are likely to be pathogenic. A negative culture result is less helpful for ruling out disease since there is always possibility that organisms were rendered nonviable by incorrect collection or handling. Similarly, positive cultures can be confounded by the presence of contaminant microorganisms and rendered extremely hard to interpret.
This article, the first in a four-part series , describes the general principles of specimen collection and how to collect a midstream specimen of urine. Nursing Times [online]; 7, Obtaining a specimen involves the collection of tissue or fluids for laboratory analysis or near-patient testing, and may be the first step in determining a diagnosis and treatment Dougherty and Lister, The procedure used to collect a specimen must minimise the risk of introducing error and protect the health and safety of both the patient and the staff who handle the sample. This article, the first in a four-part series, explores the general principles of specimen collection and describes how to collect a midstream specimen of urine MSU.

It has as its aim to respond to the challenges currently posed by everything associated with infectious diseases, from a clinical, microbiological and public health perspective. The Journal follows a rigorous selection process of the manuscripts published through the review by the best experts in each area of knowledge of the specialty. The quality of the material published is the main aim of the Editors, as well as to provide readers with the latest and most relevant information in the world of infectious diseases. The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two receding years. CiteScore measures average citations received per document published.
