NoteAdditional information related to the test.
If the isolate M. tuberculosis complex is to be speciated, enter this information in the comment field and ship Category A. A processing fee will be billed for all organisms submitted that are not in pure culture, as indicated in specimen requirements. Identification of AFB isolates is billed by individual tests performed.
Probes can be performed directly from Middlebrook 7H9 broth. MGIT is not suitable for direct probe testing.
