Specimen Type Describes the specimen type needed for testing


Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.

If susceptibilities are desired when this test is ordered, also order ZMMLS / Antimicrobial Susceptibility, Aerobic Bacteria, MIC. Each pathogen isolated will then be tested with the appropriate susceptibility panel. Charges are added for each susceptibility test performed.


Forms: If not ordering electronically, complete, print, and send a Microbiology Test Request Form (T244) (


Specimen must arrive within 48 hours of collection


Specimen source is required.


Submit only 1 of the following specimens:



Specimen Type: Sputum, expectorated or induced

Container/Tube: Sterile container

Specimen Type: Bronchial aspirate or washing, bronchoalveolar lavage, endotracheal, or tracheal

Container/Tube: Sterile container     

Specimen Volume: Entire collection


Specimen Type: Throat swab

Container/Tube: Modified Stuart transport device

Specimen Volume: Entire specimen

Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.

2 mL

Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected
