Specimen Type Describes the specimen type needed for testing

Varies

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.

Forms: If not ordering electronically, submit a Microbiology Request Form (Supply T244) with the specimen.

 

Specimen source is required.

 

Submit only 1 of the following specimens:

 

Specimen Type: Fluid

Sources: Spinal, body, amniotic, ocular

Container/Tube: Sterile container

Collection Instructions: Do not centrifuge.

 

Specimen Type: Respiratory

Sources: Bronchial washing, bronchoalveolar lavage, nasopharyngeal aspirate or washing, sputum, tracheal aspirate

Container/Tube: Sterile container

Specimen Volume: 1.5 mL

 

Specimen Type: Genital

Sources: Cervix, vagina, urethra, anal/rectal, other genital sources

Container/Tube: BBL CultureSwab (Supply T092)

Specimen Volume: Swab

Collection Instructions: Place swab back into swab cylinder.

 

Specimen Type: Miscellaneous

Sources: Dermal, eye, nasal, saliva, throat

Container/Tube: BBL CultureSwab (Supply T092)

Specimen Volume: Swab

Collection Instructions: Place swab back into swab cylinder.

 

Specimen Type: Tissue

Sources: Brain, colon, kidney, liver, lung, etc.

Container/Tube: Sterile container with 1 to 2 mL of sterile saline or multi-microbe medium (M5) (Supply T484)

Specimen Volume: Entire collection

Collection Instructions: Submit only fresh tissue.

 

Specimen Type: Urine

Container/Tube: Sterile container

Specimen Volume: 1 mL

Collection Instructions: Collect a random urine specimen.

 

Specimen Type: Bone marrow

Container/Tube: Lavender top (EDTA)

Specimen Volume: 0.5 mL

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.

Body/Ocular Fluid, Spinal Fluid, or Urine: 0.3 mL/Respiratory: 1 mL
