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.
An Overview of the PCR Lab Test. The PCR lab test (polymerase chain reaction) was developed to overcome the obstacle of quickly replicating DNA for research use. Developed in the 1980s, the PCR lab test is widely applied in medicine, from identifying new viruses to testing for bacterial illness. An alternate application is criminology, where it is used to help find potential perpetrators.
