Antimicrobial Susceptibility - Streptococcus pneumoniae
Also known as: MA SPN
Use
This test is utilized to determine the in vitro susceptibility of Streptococcus pneumoniae to a selection of antimicrobial agents. Accurate susceptibility results can guide therapeutic decisions and help in the management of infections caused by this organism, ensuring effective treatment and mitigating the risk of resistance development. Streptococcus pneumoniae is a significant pathogen responsible for various infections, and appropriate antimicrobial therapy is crucial for patient outcomes.
Special Instructions
For accurate results, it is important to submit actively growing isolates in pure culture. An additional handling fee will be applied if the organisms submitted are not in pure culture as specified in the specimen requirements. Ensure that the isolate identification and specimen source are clearly indicated with each submission.
Limitations
Susceptibility testing is performed by broth microdilution using custom-made MIC panels and interpreted according to CLSI guidelines. However, results should be interpreted in conjunction with the patient's clinical presentation, and it is important to consider that susceptibility may vary based on specific bacterial strains and their unique resistance mechanisms. Mixed cultures or non-viable organisms will lead to unacceptable results and potential rejection of the specimen.
