We now perform the Platelet Function Assay Test (PFA). The PFA test is a new laboratory screening test of platelet function that measures both platelet adhesion and aggregation (primary hemostasis). Common clinical applications include the following:

  • Preoperative evaluation of platelet function
  • Evaluation of women with menorrhagia
  • Determining the presence of drug-induced platelet dysfunction
  • Determining patient compliance with aspirin and other antiplatelet drugs
  • Determining platelet functionality in high-risk pregnancy
  • Evaluation of patients with suspected inherited or acquired platelet disorders, such as von Willebrand disease (vWD)
  • Evaluation of the bleeding patient
  • Monitoring DDAVP treatment in patients with Type I vWD

Specimen Handling 

Client Services 804-828-PATH (828-7284); 1-800-363-9234

Coagulation tests are extremely sensitive to methods of collection and preservation. It is important that the sample collection and processing instructions be followed so accurate test results can be obtained. 

Unacceptable Specimen Samples
Samples which are incorrectly collected, labeled, processed, or transported will not produce accurate results. When a sample is not acceptable, you will be notified by telephone.

If you have any question prior to collection or transportation of a sample, please contact the Coagulation Laboratory at (804) 628-5736 for more information. 

The Clinical Pathology Receiving area is located on the 6th floor of the Clinical Support Center (CSC) building at 403 N 13th Street in Richmond, VA; phone (804) 828-6767.

 

Test Results 

Test results will be phoned and faxed by the Coagulation staff to the ordering institution upon completion of testing. Pathology Client Services will auto fax the test results to the ordering institution. These results should be received the next business day after test completion. If you would like results mailed to an additional person, please include this information on the test requisition form.
