Name: Protein Electrophoresis, reflex to Immunofixation
Test Name: Protein Electrophoresis, reflex to Immunofixation
Health Link Test Code: HCSPEPR
LIS Test Code: SPEPR
CPT Code(s): 84165, 84155; if reflexed to immunofixation add 86334
Serum protein electrophoresis and total protein. Reflex to serum immunofixation if applicable.
Methodology: Gel Electrophoresis and Biuret
Frequency Recommendations: Unless clinically indicated, frequency to monitor patient is recommended no more than every 30 days. Serum protein electrophoresis is used to evaluate and follow a monoclonal gammopathy. Immunofixation is used to detect and type a monoclonal gammopathy.
Days Performed: Mon-Fri, dayshift - day varies.
In-Lab Turnaround Time: 3 - 5 days.
Stat In-Lab Turnaround Time: Not available stat.
Collection Container: Red top
Also Acceptable: Red cap with yellow ring (SST)
If there is the possibility that the patient has cryoprotein, specimens MUST BE DRAWN AND KEPT WARM AT 37°C UNTIL AFTER PROCESSING IS COMPLETE.
Before collection, pre-warm a collection tube (e.g., in an infant heel warmer). Have another infant heel warmer on hand to deliver the blood to the laboratory after collection. Keep specimen at 37°C by wrapping a hot pack (infant heel warmer) around the tube immediately after collection. Transport specimen to laboratory within 10 minutes of collection. Contact laboratory if unable to assure delivery within 10 minutes.
Collection Volume: 3 mL
Pediatric Collection Volume: 1 mL
3 months at -20°C. Note: Avoid repeat freeze and thaw.
Sample Analyzed: Serum
Testing Volume: 1 mL
Pediatric Testing Volume: 0.2 mL
Centrifuge and transfer cell-free serum to plastic vial. Refrigerate.
IMPORTANT: IF THE PATIENT HAS A CRYOPROTEIN, keep the blood specimen at 37°C during entire processing procedure. Place collection tube in the 37°C incubator for two hours. Spin tube at 1730 G-force for 10 minutes at 37°C. Remove spun serum to labeled tube. Put WARM sticker on tube and refrigerate.
Outreach Specimen Processing:
IF THE PATIENT HAS A CRYOPROTEIN, specimen MUST be collected and processed using the Collection and Specimen Processing procedures above prior to transport. Write WARM on the tube and transport specimen with coolant pack after processing is complete.
Transport speciment to Laboratory. Transport with coolant pack if coming from clinic location.
IF THE PATIENT HAS A CRYOPROTEIN, transport to the laboratory within 10 minutes of collection. Keep specimen at 37°C wrapping tube in a hot pack (infant heel warmer). Specimen MUST be processed using the Specimen Processing procedure above prior to transport if coming from clinic location. Write WARM on the tube and transport specimen with coolant pack after processing is complete.
Grossly hemolyzed specimens are not acceptable.
> 1 year and up:

|Alpha 2||0.46-0.98 g/dL|
A written interpretive report with the scan is issued as a separate report.
Reference range not available for patients <12 months of age.
Interpretation Type: Reference Interval
