Comments

Patient samples will be batch-tested. If results are desired within 24-48 hours after collection, contact the Coagulation Lab at 614-722-5364. If a next-day result is desired, fresh whole blood is required. Transport the whole blood specimen so that it is received within four (4) hours of collection, and between 7:00 a.m. – 11:00 a.m., Monday through Thursday.
