Rapid MHR-SIR media specific to SIRscan readers make it possible to get AST results within 6 to 8 hours for most fast-growing bacteria.
Reading on the SIRscan ORION automated system is continuous every 1/2 hour until the final result is obtained.
In cases of weak growth or specific results, a reading after 18 hours is recommended (carried out automatically on the SIRscan ORION).
