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.

Forms: If not ordering electronically, complete, print, and send 1 of the following forms with the specimen:

Microbiology Test Request Form (T244) (

Neurology Test Request Form (T732) with the specimen (


Specimen source is required.


Submit only 1 of the following specimens:


Specimen Type: Amniotic fluid

Container/Tube: Amniotic fluid container

Specimen Volume: 0.5 mL

Collection Instructions: Do not centrifuge.


Specimen Type: Spinal fluid

Container/Tube: Sterile vial

Specimen Volume: 0.5 mL

Collection Instructions: Do not centrifuge.


Specimen Type: Fresh tissue

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: Ocular fluid

Container/Tube: Body fluid container

Specimen Volume: 0.3 mL

Collection Instructions: Do not centrifuge.

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.

Amniotic Fluid, Ocular Fluid, Spinal Fluid: 0.3 mL/Tissue: NA

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