WebPlatelet-Poor Plasma (PPP) is blood plasma with very low number of platelets (< 10 X 10 3 /μL). Traditionally, PPP was recommended for use in platelet aggregation studies to both adjust the Platelet-rich plasma concentration, and to serve as a control. PPP may have elevated levels of fibrinogen, which has the ability to form a fibrin-rich clot once activated. WebFor patients who repeatedly have platelet clumps which preclude determination of an accurate platelet count, it is now possible to order a platelet count from a citrate tube. In many cases the EDTA in a lavender top tube causes the platelet clumping which does not occur in a blue top (citrate tube). The Epic order code is LAB7882.
