Interpretive Data

An additional processing fee will be billed for all organisms submitted for identification that are not in pure culture, as indicated in specimen requirements. Identification of referred isolates is performed and billed by the extent of tests required for identification. When the specimen submitted contains both mold and yeast, both will be identified.

Differentiation between Candida albicans and Candida dubliniensis is performed based on a specimen source and when susceptibility testing is requested.

Organisms submitted for identification are kept for 7 days; if organism fails to grow, the client will be contacted. All original submissions are held until identification is completed or the test is cancelled.
