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.
Absence or presence of white blood cells in the Gram stain can help establish that an adequate sample was obtained as white blood cells are frequently present with an infection. A Gram stain may also be performed as part of the evaluation of a culture.When bacteria grow on/in a nutrient media in the laboratory, a Gram stain is performed to help determine the type of bacteria present and to help determine what other tests may need to be performed to definitively identify the cause of infection.Fungi, including yeast, may also be detected with a Gram stain.bsence or presence of white blood cells in the Gram stain can help establish that an adequate sample was obtained as white blood cells are frequently present with an infection.
