BETA-2 TRANSFERRIN

Geisinger Epic Procedure Code: LAB1843             Geisinger Epic ID: 35211
       

SPECIMEN COLLECTION
Specimen type:
 Body fluid, excluding CSF
Preferred collection container:
Specimen required:
0.5 mL body fluid; minimum 0.2 mL.
Special notes:
 Collect 0.5 mL (minimum 0.2 mL) of body fluid (nasal, otic, etc.). 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.
    • Place cotton swab in as small a container as possible (for example: a tightly-stoppered test tube).
    • Do NOT add any additional fluid to swab including, but not limited to, saline or microcollection fluids.
    • Tightly seal container.
    • Indicate specimen type on request form.
    SPECIMEN PROCESSING
    Transport temperature:
    		 Room temperature.
    Specimen stability:
    		 Room Temperature: 7 days. Refrigerated: 7 days. Frozen: 7 days.
    Rejection criteria:
    		 Do not send CSF. CSF is not an acceptable specimen for this test; this test is used to detect CSF leakage in other body fluids (e.g., ear, nose, eye).

    Test includes:
    		 Beta 2 transferrin.
    Methodology:
    Electrophoresis
    Immunofixation
    Synonyms:
    CSF in other body fluid
    Quest test code 10640
    B2TRF
    Clinical significance:
    		The presence of Beta-2 Transferrin in nasal or ear fluid, or in wound drainage following head trauma, surgery or from tumors or congenital malformation, clearly indicates CSF leaking into these passages or fluids creating a pathway for life-threatening central nervous system infection.
