He provides the scientific and administrative direction of a clinical microbiology laboratory. Such laboratory receives almost any clinical specimen, including swabs, feces, urine, blood, sputum, cerebrospinal fluid, synovial fluid, possible infected tissue. The work here is mainly concerned with cultures, to look for suspected pathogens which, if found, are identified based on biochemical tests. In addition, sensitivity testing is carried out to determine whether the pathogen is sensitive or resistant to a suggested medicine. Results are reported with the identified organism(s) and the type and amount of drug(s) that should be prescribed for the patient.
