Currently, the antimicrobial susceptibility test, the so called antibiogram, requires growing a culture for 1-2 days in order to to identify the pathogen. The precise timescale depends on the type of bacteria. After this, an additional 12–24 hours are needed to conduct an antibiotic sensitivity screen. In the case of slow growing bacteria, e.g. M. tuberculosis, such a test may take up a full month to complete.
