Notes
1. Send PURE culture only. If the specimen submitted is mixed, there will be no workup pending clarification with the client. There will be separate charges for each organism that requires susceptibility testing. 2. If broth is submitted, it will be subbed onto an agar plate for isolation. This process will delay test results. 3. Drugs tested are: Amikacin, Azithromycin, Ciprofloxacin, Clarithromycin, Ethambutol, Ethionamide, and Rifampin. 4. MAC susceptibility testing is recommended in the following situations: (NCCLS M24-T2, Vol 20). a. Clinically significant isolates from patients on prior macrolide therapy; b. Isolates from patients who develop bacteremia while on macrolide prophylaxis; c. Isolates from patients who relapse while on macrolide therapy; d. Initial isolates from blood or tissue (patients with disseminated disease) or from clinically significant respiratory samples (e.g., sputum or bronchoalveolar lavage fluid) to establish baseline values.
