Resistell AST

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 vibration 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 hours. Resistell provides information on which antibiotic should be used to treat the patient.
