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

Specimen Type Describes the specimen type validated for testing

Body Fluid

Additional Testing Requirements

If specimens are collected from multiple sites on the body (ie, left and right), each specimen must be sent under a separate order.

Necessary Information

Indicate specimen source. Include whether the source is from the right or left side of the body, if applicable.

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

Specimen Type: Body fluid

Sources: Nasal, otic, wound, etc

Container/Tube:

Preferred: Sterile container, syringe, test tube, or microtube

Acceptable: Plain cotton swab or gauze

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 plain cotton swab or gauze.

3. If gauze is used to collect specimen, circle area on the gauze where specimen was collected.

4. Place cotton swab or gauze in as small a container as possible (eg, plain test tube or collection container).

5. Do not collect specimen with a culture swab.

6. Do not add any liquid to the swab or gauze.

Additional Information:

1. Samples collected from above the shoulders risk salivary contamination, which can degrade the beta-2 transferrin protein. These samples should be frozen immediately following collection and kept frozen until testing is performed.

2. 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.

3. Samples collected with additives such as microbiology media (eg, Stuart or Amies liquid medium) or TransFix/EDTA (used for analyses in flow cytometry) yield uninterpretable results and will be rejected.

Specimen Minimum Volume Defines the amount of sample necessary to provide a clinically relevant result as determined by the Testing Laboratory

0.5 mL

Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the performing laboratory, alternate acceptable temperatures are also included
