The procedure involves the following steps: 1. Sample Collection: A sample is collected from the patient, such as a swab, urine, or blood. 2. Inoculation: The sample is cultured on an agar plate. 3. Application of Disks: Antibiotic disks are placed on the inoculated agar. 4. Incubation: The plate is incubated to allow bacterial growth. 5. Measurement: The zones of inhibition around the disks are measured to determine the bacteria's susceptibility.
