  • Platelet Concentrate

    Test Name:Platelet Concentrate
    Epic Order Code:Orderable by requisition only. State number of single units needed (multiple or single donor) on requisition.
    CPT Code:86965  
    Specimen(s) Type:Whole blood, 5.0 mL
    Acceptable Container(s):
    Testing Schedule:24 hours/day, 7 days/week
    Turn Around Time:STAT: 1 - 2 hours (depending on availability of platelet concentrates)
     Routine: 6 hours
    Collection Information:A platelet count should be done before platelets are ordered and must be recorded on the Requisition Form. A one hour post transfusion platelet count is recommended. ABO/Rh is required. Obtain by standard collection procedures.
    Transport Information:Deliver to lab immediately. All specimens must be signed into the laboratory.
    Reference Clients:If unable to deliver to the lab immediately, store and transport specimen at 2-8° C. Specimen must be received in the lab within 48 hours. All specimens drawn as outpatients will be for informational purposes only - not for transfusion.
    Causes for Rejection:Improperly labeled, incorrect container, contaminated, insufficient quantity, incorrect/delay in transport, grossly hemolyzed, failure to provide a properly completed Requisition Form and/or a Blood Infusion form.
    Reference Range:NA  
    Additional Information:A routine order of multiple donor units is six (6) units. One single apheresis donor platelet is equivalent to approximately four to six multiple donor platelet concentrates. After pooling, platelet concentrates must be transfused within four hours. When platelets have been requested for a patient and they have been pooled, and/or permitted to expire with out being infused, the patient will be charged for the product.
     Indications for Use: Treatment of patients with thrombocytopenia or functionally abnormal platelets. Multiple donor platelet concentrates usually contain 5.5 x 10 10 platelets. Each unit of multiple donor plateltes would be expected to increase the platelet count of a hematologically stable adult (70 Kg) about 5-10,000. A single donor apheresis platelet concentrate usually contains 3x10 11 platelets and would be expected to increase the platelet count of a hematologically stable 70kg adult by approximately 60,000. Chills, fever and allergic reactions may occur. Repeated platelet transfusion may lead to a refractory state in which the patient responds only to HLA matched platelets that must be obtained by special arrangements.
