Test ID: CTBID    
Culture Referred for Identification, Mycobacterium and Nocardia, Varies

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

When this test is ordered, the reflex test may be performed and charged. All mycobacteria and Nocardia (including aerobic actinomycetes) submitted will be identified and billed as appropriate.

 

See Culture Referred for Identification Mycobacterium and Nocardia Algorithm in Special Instructions.

Specimen Type Describes the specimen type validated for testing

Varies

Shipping Instructions

1. See Infectious Specimen Shipping Guidelines in Special Instructions.

2. Place specimen in a large infectious container (T146) and label as an etiologic agent/infectious substance.

Necessary Information

1. Specimen source is required.

2. Isolate description is required: Gram stain reaction, morphology, tests performed.

Specimen Required Defines the optimal specimen required to perform the test and the preferred volume to complete testing

Specimen Type: Organism in pure culture

Supplies: Infectious Container, Large (T146)

Container/Tube: Middlebrook (7H10 or 7H11) or Lowenstein-Jensen medium slant or in broth (eg, Mycobacteria Growth Indicator Tube [7H9] broth)

Specimen Volume:

Visible growth of isolate on solid media

Isolate in broth media: > or =3 mL

A minimum volume of 3 mL is recommended in order to perform all initial testing, this may include: stains, sub-culture media, nucleic acid probes, and any additional testing that may be required to determine the identification. If the broth sample volume is <3 mL, initial testing may be limited, and increased turnaround time is likely.

Collection Instructions: Organism must be in pure culture, actively growing. Do not submit mixed cultures.
