01.08.2014· Platelet aggregation studies test the clumping response of platelets to various platelet activators (eg, ADP, collagen, arachidonic acid, thrombin, epinephrine, ristocetin) as continuously recorded by a light transmission aggregometer. With some aggregometers, the secretion of platelet granules, another indicator of platelet function, may also ...

01.01.2019· Before LTA is performed on an aggregometer, the respective limits for no aggregation (0%) and aggregation are set on the instrument, using the PRP suspension and the subject's autologous platelet-poor plasma (PPP) (or buffer if testing washed or gel-filtered platelets).1, 2 After prewarming the sample, an agonist or an agglutinating ...
The instrument should be "blanked" using platelet free plasma, if platelet rich plasma was used by accident, the instrument would not recognize any platelet aggregation. As well, the platelet rich plasma should have minimal contact with air, as this will cause a change in the pH of the plasma.
Integrated platelet aggregation provides cost-effective system consolidation for detection of inherited, acquired, or drug-induced platelet disorders. Streamlined workflow with fewer instruments and less specialized staff leads to significant time and resource savings.
Comprehensive platelet aggregation studies are a standard and accepted part of any coagulation work-up following initial screening tests, PT/INR, aPTT and von Willebrand factor testing. Platelet function testing is an important part of the evaluation of common and rare bleeding disorders [1, 2, 3, 8].

Measurement. Platelet concentration is measured either manually using a hemocytometer, or by placing blood in an automated platelet analyzer using electrical impedance, such as a Coulter counter. The normal range (99% of population analyzed) for platelets in healthy Caucasians is 150,000 to 450,000 per cubic millimeter (a mm 3 equals a microliter). or 150–450 × 10 9 per liter.
