Preanalytical quality control procedures necessary when performing platelet aggregation studies include assessing patient medications before obtaining the specimen. Patients may be taking medications that affect platelet function, such as aspirin or other antiplatelet drugs, which can alter the results of the study. Obtaining the specimen after a 12-hour fast or performing a bleeding time test is not necessary for platelet aggregation studies. Collecting the specimen in a glass tube may also not be necessary as long as the anticoagulant and storage conditions meet the requirements for the specific test being performed.
