BETA-2 TRANSFERRIN: DETECTION OF SPINAL FLUID IN OTHER BODY FLUIDS

Test Code BETA2-M 
Test BETA-2 TRANSFERRIN: DETECTION OF SPINAL FLUID IN OTHER BODY FLUIDS 
Methodology Electrophoresis/Immunofixation-Peroxidase Antisera/Dimethylformamide Visualization 
Description Useful for detection of spinal fluid in body fluids such as ear or nasal fluid.

1. Performance characteristics have been determined by the performing laboratory. Results should be interpreted in conjunction with clinical findings. 

Specimen Container/Tube: Body fluid container(s)
Specimen Volume: 0.5 mL of body fluid (nasal, otic, etc.)
Collection Instructions:
1. Direct collections may be done with a pipet, syringe, test tube, or microcollection device. If submitting a syringe, remove needle. Add cap to end of syringe.
Note: 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. 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.
D. Indicate specimen type.

2. Send specimen in plastic vial.
