Antimicrobial susceptibility testing

Software and Devices

Offering a flexible degree of automation


The MICRONAUT6 Software offers rapid and standardized reading of MICRONAUT-S and MICRONAUT-AM MIC plates as well as automated determination and interpretation of MIC values according to EUCAST and / or CLSI standards by using MICRONAUT systems.


All patient data (specimen number, name, date of birth) and test types can be manually entered or imported from the mainframe. The MICRONAUT6 software creates work lists that define an optimized inoculation procedure and ensure efficient use of MICRONAUT-S and MICRONAUT-AM test plates.


The user-friendly MICRONAUT6 software is used for fast and standardized reading, evaluation and validation of all MICRONAUT plates. The MICRONAUT6 software includes a quality control system and an expert system for validating the AST results regarding plausibility and effectiveness.

The MICRONAUT6 software checks the plausibility of the AST results by comparing the species ID with typical resistance profiles to ensure there are no inconsistencies (expert rules).


The MICRONAUT6 software ensures optimal conditions for laboratories by providing patient data registration and ready to deliver results. The software can be extended by a quality control and statistical program resulting in integrated control of susceptibility testing with official quality control strains.


To guarantee fast, standardized and consistent reading of MICRONAUT-S and MICRONAUT-AM MIC plates, the photometer TECAN SUNRISE™ is used to ensure reliable AST and AFST results.
