Turnaround time
The turnaround time (TAT) for results of the Galleri® test is 10 business days from the time a specimen is received at the laboratory for processing. Shipping to the laboratory typically takes 1 to 2 business days.
For example, if a specimen is picked up by FedEx on a Monday, the laboratory will receive it on a Tuesday. Allowing for 10 business days, the report can be expected by the end of the second Tuesday after the Monday the specimens were submitted.
Logistical factors beyond the control of the laboratory can affect the time between blood draw and results reporting and are considered exceptions to the 10-business day turn-around time commitment. These cases may include but are not limited to:
Delays in shipping specimens from a customer’s location or a missed FedEx pickup.
Logistical delays that occur during transport of the specimen to the laboratory, or
Unforeseen disasters that significantly impact laboratory operations.
In an event where the stated turn-around time cannot be met, you will receive a phone call from GRAIL Customer Service, which will provide the reason for the delay and a new estimate for when the test results will be reported.

Holiday schedule
Only schedule blood draws when blood can be shipped to the laboratory within 24 hours of the time of collection. GRAIL will issue guidance for “Do Not Ship” dates, which should be observed in order to minimize transit times and maintain specimen integrity. Generally, these are days when FedEx is not operational due to holiday closures. GRAIL Customer Service will notify your facility in advance of these dates.

How we track Galleri specimen collection kits in transit
Once your package has been received by FedEx, the information immediately appears in GRAIL’s Laboratory Information Management System, or LIMS. Our logistics team uses this tracking information to trace the shipment from the time it’s received by FedEx to the time it’s delivered to the laboratory.
