Diagnostic medical sonographers and cardiovascular technologists and technicians, including vascular technologists, also called diagnostic imaging workers, operate special imaging equipment to create images or conduct tests.
Microbiology includes the study of both bacteria and viruses. Many tests in microbiology have been traditionally manual procedures. While some tests such as a rapid Strep or influenza screen can be done in 15-20 minutes, some cultures may take several days or even weeks depending on how fast the organisms grow.his section is also highly automated. The tests performed include hemoglobin, white blood cell counts, red blood cell counts, and white cell differentials, which tell the medical provider what types of white cells, are present in the patientâs blood.
Tests are performed in vitro, and measure the growth response of an isolated organism to a particular drug or drugs. The tests are performed under standardized conditions so that the results are reproducible. The test results should be used to guide antibiotic choice. The results of antimicrobial susceptibility testing should be combined with clinical information and experience when selecting the most appropriate antibiotic for your patient. What is the output from antimicrobial susceptibility testing? The raw data are either in the form of a zone size or MIC. CLSI has published interpretation criteria for these tests, which has come from extensive testing and clinical correlation.
