BETA 2 TRANSFERRIN

Test code:
B2TRF
Specimen type:
Ear/nasal discharge
Tube type / collection container:
Specimen collection notes:
Collect 0.5 mL of body fluid (nasal, otic, etc.) (0.2 mL minimum). Direct collections may be done with a pipette, syringe, test tube, or microcollection device. If submitting a syringe, remove needle; and add cap to end of syringe.
NOTES: 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, specimens may be collected using cotton swabs. 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 and freeze. D. Indicate specimen type on request form. 3.
