Abstract

In the field of diagnostic medical parasitology, proper specimen collection is critical since the final laboratory results are based on parasite recovery and identification will depend on the initial quality of the samples taken. Unless the appropriate specimens are properly collected, preserved and processed, these infections may not be detected; therefore, specimen rejection criteria have become much more important. Laboratory procedures detect organisms within clinical specimens using morphological criteria, rather than culture or biochemical tests and/or physical growth characteristics. Final identification is often based on microscopic examination of stained preparations. Faecal specimen preparation generally includes one of several concentration procedures and the preparation of smears for staining. Examination of clinical material by microscope uses a number of magnifications, and multiple specimens may be required to find and confirm the identity of the suspected organism(s). With the introduction of newer immunoassays, thereare now many more options available to the diagnostic laboratory, and different laboratories will select different approaches. As methods change, however, it becomes even more critical for the laboratory to inform each client of the diagnostic procedure used, and ensure that the client understands the clinical relevance of the test results.
