Lipid Cascade With Reflex to Apolipoprotein B
CPT:
80061. If reflex testing is performed, concomitant CPT codes/charges will apply.
Special Instructions
If the triglyceride level is >800 mg/dL, a reflex to direct LDL will be performed at an additional charge. If the LDL is <130, a reflex to apolipoprotein B will be performed at an additional charge.
Expected Turnaround Time
Within 1 day
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.
