Pro-prep™ AST by Pro-Lab Diagnostics


Standardised inoculum preparation for AST - simple, rapid and EUCAST-compliant


Pro-Prep™ AST provides laboratories with a rapid, reproducible method for standardising bacterial inoculum ahead of antimicrobial susceptibility testing (AST), refined for consistent CLSI / EUCAST-compliant performance.


How it works


Stab & emulsify: Pick a colony with the Pro-Prep™ AST rod, then emulsify directly into the supplied 0.7 mL physiological saline vial.


No extra equipment: The resulting suspension conforms to CLSI / EUCAST requirements - no densitometer required.


Streak & incubate: Dip the supplied swab into the physiological saline suspension and streak the agar plate for confluent growth.


Versatile: The same technique also supports bacterial spotting for MALDI-TOF MS testing. Independently validated


Pro-Prep™ AST has been evaluated at three independent UK laboratory sites using six EUCAST- recommended NCTC®/ATCC® quality control strains. Across different media and antibiotic disc suppliers, results demonstrated 96.44–100% concordance with EUCAST target ranges, equivalent to current manual method performance. Full detail available on request.
