Test ID: BETA2    
Beta-2 Transferrin: Detection of Spinal Fluid in Other Body Fluid

Specimen Type Describes the specimen type needed for testing

Body Fluid

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.

Sources: Nasal, Otic, etc

Collection Container/Tube: Pipet, syringe, test tube, or microcollection device

Submission Container/Tube: Plastic vial

Specimen Volume: 0.5 mL

Collection Instructions:

1. If submitting a syringe, remove needle. Add cap to end of syringe.

2. If direct collection is not feasible, specimen may be collected using a cotton swab.

a. Place cotton swab in as small a container as possible (for example, a tightly-stoppered test tube).

b. Do NOT add any additional fluid to swab including, but not limited to, saline or microcollection fluids.

c. Tightly seal container.

Additional Information:

1. Although results may be obtainable on smaller specimens (perhaps as little as 0.05 mL, depending on the protein concentrations and percentage of spinal fluid in the specimen), reliable results are best obtained with an adequate specimen volume.

2. Indicate specimen type.

Forms: If not ordering electronically, submit a General Request Form (Supply T239) with the 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.
