Principle Specimens from sites that may be contaminated by indigenous flora are decontaminated and concentrated. Specimens from sites that are normally sterile are not decontaminated but are concentrated by centrifugation when possible. An AFB smear is performed on the sediment. The sediment is inoculated into AFB culture media and incubated for up to 8 weeks. Negative cultures are finalized after 8 weeks. Positive cultures are reported as soon as AFB are recovered.
Container type Sterile screw cap tube or container
Collection Instructions Using a needle and syringe, aspirate material from undrained abscesses. Transfer aspirated material into a sterile, screw-cap container. Collection of specimens on swabs is discouraged for mycobacteria culture. Collection of whole specimen, such as biopsy sample or aspirated material, is preferred. If swabs must be used, send in a sterile, screw-cap tube with 2-3 drops of sterile saline, or place in transport medium. Dry swabs are not acceptable.
Sample type Wounds, abscesses
Synonyms Abscess Culture;
Stability Deliver to Microbiology Laboratory (2M33) immediately.
