Antimicrobial Susceptibility - Fastidious Organism
Also known as: MA FAST
Use
This test is used to determine in vitro susceptibility to antimicrobial agents for fastidious bacterial organisms. It helps in deciding the appropriate antimicrobial therapy for infections caused by such organisms. Fastidious organisms often require specific growth conditions, making susceptibility testing crucial for effective treatment. The test identifies whether the organism is susceptible, intermediate, or resistant to various antimicrobial agents, thus guiding treatment strategies.
Special Instructions
Not provided.
Limitations
This test might not be applicable for mixed cultures or nonviable organisms, as they are considered unacceptable conditions for accurate susceptibility testing. Specimens that are not submitted in pure culture will require additional processing, potentially delaying results. Species identification is necessary for this test; if not provided, identification will incur additional charges. Furthermore, the test is dependent on the isolation and growth of bacteria in appropriate media, which may not be possible for all fastidious organisms.
