1. The MGB Special Coagulation Integrated Lab Service receives batches of specimens at the following times:
   • Monday through Friday:
     • BWH – 10:30 AM, 11:45 AM, 1:15 PM, and 3:30 PM
     • NWH/BWFH – 12 PM and 1:30 PM

     • HMA – 11:45 AM (Thursdays only, through BWH)
   • Saturday and Sunday:
     • BWH – 10:45 AM and 1:15 PM
2. Platelet aggregation/secretion studies are performed at BWH. Advance notice to BWH is required by emailing bwhspecialcoag@partners.org.
   • Pediatric samples can only be collected Monday through Friday from 8-10 AM and must be hand-delivered to MGH Special Coag Lab on Jackson 2 due to sample stability. Samples will be couriered to BWH immediately after receipt. No additional notification or arrangement of specimen transport is required. Testing requires 4 properly-filled blue top tubes at room temperature.
   • Adult patients from MGH should be directed to BWH Outpatient Phlebotomy at 45 Francis Street before 12 PM Monday through Friday.
3. Argatroban, bivalirudin, dabigatran, apixaban, or rivaroxaban anticoagulation interfere with some coagulation assays (see interferences link above).
4. 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.
5. Clotted, underfilled or overfilled specimens give unreliable results and will be refused.
