What is MIC Testing?
Minimum Inhibitory Concentration (MIC) testing is the gold standard method for determining antimicrobial susceptibility in clinical microbiology. MIC defines the lowest concentration of an antibiotic that prevents visible bacterial growth, providing clinicians with precise data to guide antibiotic therapy decisions.
Why MIC Testing Matters in Australian Laboratories
Australian clinical microbiology laboratories face increasing pressure from antimicrobial resistance (AMR). Accurate MIC determination is essential for appropriate antibiotic stewardship, reducing treatment failures, and preventing the spread of resistant organisms in hospital settings.
MIC Gradient Strip Method
MIC gradient strips — such as the BioMaxima BMIC, TMIC, FMIC, and RMIC strips — are plastic strips pre-impregnated with a continuous antibiotic concentration gradient. When placed on an inoculated Mueller-Hinton agar plate, they produce an elliptical inhibition zone. The point where the zone intersects the strip indicates the MIC value directly.
Advantages of Gradient Strip Testing
- Direct MIC readout — no calculation required
- Compatible with standard laboratory workflows
- Suitable for fastidious organisms
- Available for antibacterial, antifungal, antituberculosis, and resistance mechanism testing
- ISO-certified manufacturing
