Antibiotic Susceptibility Testing

Laboratory testing that determines which antibiotics effectively inhibit the growth of a specific bacterial isolate.

Key Facts

Essential for MRSA cases due to widespread and unpredictable resistance patterns.
Prevents the inappropriate use of broad-spectrum or last-resort antibiotics.
Helps avoid the development of further multidrug-resistant bacterial strains.
Results are paired with bacterial culture to form a complete diagnostic profile.

Testing is required to identify effective antibiotics due to MRSA's unpredictable multi-drug resistance patterns.

Testing confirms MRSA's inherent resistance to beta-lactams and identifies viable alternative medications.

Susceptibility testing is performed on the bacterial isolate obtained from culture.
