Microbiological culture tests are performed to identify pathogens or microorganism differences in a region. These tests provide information about the spread and characteristics of infectious agents. They are not part of routine laboratory tests. Generally, when preliminary analysis results or epidemiological data (analysis of rates/ratios) suggest an epidemic, a specialist physician may request a culture test to determine the specific microorganism causing the infection. Culture is a vital laboratory test for precisely identifying the type of microorganism causing the disease.
