Protein Electrophoresis, serum
|Test Update Information||Effective 1/20/15, all serum protein electrophoresis requests will be tested by Capillary Electrophoresis.
New reference range change effective 1/20/15.
|Performed by||China Basin Chemistry|
|In House Availability||Monday-Friday (day shift) as needed|
|Method||Capillary Electrophoresis by Sebia Capillarys 2 Flex|
|Container type||Gold top|
|Amount to Collect||2 mL blood|
|Preferred volume||1 mL serum|
|Min. Volume||0.4 mL serum|
|UCSF Rejection Criteria||Plasma sample received|
|Processing notes||Refrigerate serum|
|Normal range|| For patients ≥ 1 year old:
Note: Reference intervals are not available for patients < 1 year old. Results should read lower due to a lower total protein in patients who are < 1 year old.
Reference range adopted from ARUP Laboratory and verified by UCSF Clinical Labs by running 39 outpatient samples with normal ALB, AST, ALT, LD, creat/eGFR, & CRP.
|Synonyms||SPEP; PEP; paraprotein|
|Stability||Refrigerated 10 days, frozen 1 month|
|Turn around times||1-3 days|
|Additional information||Total Protein is automatically included in test request.
Most monoclonal cryoglobulins are detected by serum electrophoresis, but if cryoglobulins are suspected and the PEP is normal, order Cryoglobulin, Quantitative. Most monoclonal proteins are also detected by electrophoresis, but if negative in a patient with a high suspicion of a monoclonal gammopathy it may be detectable by immunofixation electrophoresis or by free light chain immunoassay.
An interpretation of this test by a laboratory physician will automatically be performed and billed for separately.
