Antimicrobial Susceptibility Testing (AST) is a laboratory procedure used to determine the effectiveness of antibiotics against specific bacteria. By exposing bacteria to various antimicrobial agents, healthcare professionals can identify which drugs are effective in inhibiting bacterial growth. This information is crucial for selecting the appropriate treatment for infections. AST helps guide clinicians in prescribing the right antibiotics, reducing the risk of antibiotic resistance. It ensures that patients receive effective therapy while minimizing the use of unnecessary medications. Accurate testing is essential for improving patient outcomes and controlling the spread of resistant bacteria in the community.
