Identification of acid-fast organisms (AFB) isolated in pure culture.
- Patient Preparation
- Actively growing organism, in pure culture.
- Specimen Preparation
- Transport sealed container with pure culture on solid or in liquid media. Place each specimen in an individually sealed bag.
- Storage/Transport Temperature
- Room temperature. If culture is suspected of being a microorganism listed as infectious substance affecting humans on IATA list, submit specimen according to Biological Substance, Category A, shipping guidelines.
- Unacceptable Conditions
- Mixed cultures or non-viable organisms. Organisms submitted on an agar plate.
- Indicate source of organism and any other pertinent information, such as the growth rate of the organism or DNA probe results. Probes can be performed directly from Middlebrook 7H9 broth. MGIT is not suitable for direct probe testing.
- Ambient: 2 weeks; Refrigerated: 2 weeks; Frozen: 2 weeks
Identification of AFB isolates is billed by individual probes and tests performed.
