PlateletIndizes
PlateletIndizes, or platelet indices, are hematology parameters derived from automated complete blood counts that describe platelet size, volume, and distribution. The main indices are mean platelet volume (MPV), platelet distribution width (PDW), plateletcrit (PCT), and the platelet large cell ratio (P-LCR). These indices provide information about platelet production in the bone marrow and platelet activation and turnover.
MPV is the average size of circulating platelets, while PDW reflects the variation in platelet size within
Interpretation of platelet indices is context-dependent. MPV tends to be higher when platelets are produced rapidly
Preanalytical considerations are important, as EDTA-induced platelet swelling can artificially alter MPV if samples are stored
Clinically, platelet indices are used as supplementary data in evaluating bleeding disorders, platelet production abnormalities, and
