Collection Instructions: Must indicate anticoagulant status to avoid delay. A Hematology consult is REQUIRED for inpatient samples (except for patients in Hematology/Oncology ward). Referred-in patients and outpatients can be tested without a Hematology consult. Referred-in samples must be accompanied by an ADAMTS-13 Request Form filled out by the requesting site. For in- and out-patients only, if the ADAMTS-13 activity is < 0.10 U/mL, the ADAMTS-13 inhibitor test will be reflexed. Write your initials, date and time of collection on the collection label. Transportation: In/Outpatients: Send whole citrated blood at room temperature as soon as possible. Referred-in: Send frozen citrated plasma on dry ice. All samples must be sent to the Core Laboratory. Stability: Specimens are stable for 4 hours post collection at room temperature. Specimens which are not tested within 4 hours can be double-spun to remove the citrated plasma. The citrated plasma is stable at -20°C for up to two weeks or -70°C for up to six months. Sample Rejection Criteria: Clotted sample, grossly hemolyzed samples, unlabeled or samples with insufficient quantity will be rejected. |
