- Wolman Disease
When submitting whole blood, specimen must arrive at the testing laboratory within 4 days of collection.
Expected Turnaround Time
4 - 14 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.
