Antimicrobial Susceptibility Testing (AST) on Streptococcus pneumoniae.
- Pneumococcal meningitis
Pure culture isolated from a normally sterile site.
Isolate provided on culture medium.
Send as growth on culture medium (preferred) or on a swab in transport medium. Chocolate or charcoal media are recommended. Cultures can be also shipped frozen on dry ice.
Shipping of specimens shall be done by a TDG certified individual in accordance with TDG regulations. For additional information regarding classification of specimens for the purposes of shipping, consult either Part 2 Appendix 3 of the TDG Regulations or section 3.6.2 of the IATA Dangerous Goods Regulations as applicable.
