Description

The Coagulation Laboratory is in operation 7 days a week, 8 am to 4:00 pm, except for holidays, when it is closed. When the laboratory is closed, specimens should be delivered to the Core Laboratory on Gray 5. Many of the tests performed are of a batch nature.

Notes

1. Argatroban, bivalirudin, dabigatran, apixaban, or rivaroxaban anticoagulation interfere with some coagulation assays.
2. When multiple tests are ordered simultaneously, a maximum of 5 blue top tubes is typically sufficient for all tests. Please contact the lab at 617-724-2969 for minimum volume requirements PRIOR to drawing more than 5 tubes.
3. Clotted, underfilled or overfilled specimens give unreliable results and will be refused.
4. Platelet aggregation studies are performed Monday, Wednesday, Friday and must be scheduled in advance (call 617-724-2969). Samples should not be drawn earlier than 8am and must be received by 12pm
   – Platelet aggregation samples must be received within 2 hours of collection
   – 8 blue top tubes at room temperature are needed for platelet aggregation.
