Result Turnaround Time
2 - 4 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.
Test Includes
ADAMTS13 Activity; Complement, Total (CH50); D-Dimer; Factor VIII Activity; Lactic Acid Dehydrogenase (LD); von Willebrand Profile
Use
Assessment of patients at high risk of COVID-19-associated thrombotic microangiopathy.
Limitations
For von Willebrand Factor (vWF) Antigen [086280]: This test was developed and its performance characteristics determined by Labcorp. It has not been cleared or approvedby the Food and Drug Administration.

Specimen Requirements
Specimen
Serum and plasma
Volume
2 mL serum and 4.5 mL plasma (sodium citrate)
Minimum Volume
1 mL serum and 3 mL plasma (sodium citrate) (Note: This volume does not allow for repeat testing.)
Container
Gel-barrier tube and blue-top (sodium citrate) tube
Collection Instructions
Blood should be collected in a blue-top tube containing 3.2% buffered sodium citrate. Evacuated collection tubes must be filled to completion to ensure a proper blood to anticoagulant ratio. The sample should be mixed immediately by gentle inversion at least six times to ensure adequate mixing of the anticoagulant with the blood. A discard tube is not required prior to collection of coagulation samples. When noncitrate tubes are collected for other tests, collect sterile and nonadditive (red-top) tubes prior to citrate (blue-top) tubes. Any tube containing an alternate anticoagulant should be collected after the blue-top tube. Gel-barrier tubes and serum tubes with clot initiators should also be collected after the citrate tubes. Centrifuge and carefully remove the plasma using a plastic transfer pipette, being careful not to disturb the cells. Transfer the plasma into a Labcorp PP transpak frozen purple tube with screw cap (Labcorp No. 49482). Freeze plasma within four hours of blood collection and maintain frozen until tested. To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit seperate frozen specimens for each test requested.
Storage Instructions
Frozen: Serum and plasma
Room temperature: Serum
