Antibiotic sensitivity culture the bacteria. This can help in the diagnosis. Once a culture is established, there are two possible ways to get an antibiogram: Once the MIC is calculated, it can be compared to known values for a given bacterium and antibiotic: e.g. a MIC > 0,06 µg/ml may be interpreted as a penicillin-resistant "Streptococcus pneumoniae". Such information may be useful to the clinician, who can change the empirical treatment, to a more custom-tailored treatment that is directed only at the causative bacterium. Often clinical specimens are sent to the clinical laboratory for culture and sensitivity (C&S), which is culture and
