Test Includes

Serum protein electrophoresis and automatic reflex to serum immunofixation (IFE) at additional charge if M-spike is present or abnormal pattern observed

Expected Turnaround Time

3 - 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.
