CPT:
84155; 84165
Synonyms
- Interpretation, Protein Electrophoresis With Reflex to IFE, Serum
Test Includes
Serum protein electrophoresis with interpretation and automatic reflex to serum immunofixation (IFE) at additional charge if M-spike is present
Expected Turnaround Time
4 - 5 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
