Resistell proposes an alternative to culture based antibiogram, the current gold standard in antibiotic susceptibility testing. Our offering is a diagnostic device. The rapid AST method is based on the detection of movement caused by living bacterial cells. Because the test is growth independent rapid AST, we reduce the time taken to get a result from days to minutes. Resistell provides information on which antibiotic should be used to treat the patient, and the concentration at which it should be administered.

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.
