    Thrombosis and haemostasis·1992

    Area of Science:

    • Hematology
    • Clinical Pathology
    • Hemostasis and Thrombosis

    Background:

    • Platelet function tests are crucial for diagnosing bleeding disorders.
    • Variability in current assays hinders accurate diagnosis and reproducibility.
    • Standardization is needed to establish reliable reference ranges.

    Purpose of the Study:

    • To present standardized methods for key platelet function tests.
    • To determine normal ranges for these standardized tests.
    • To propose a comprehensive platelet function profile for clinical use.

    Main Methods:

    • Standardization of bleeding time, capillary fragility, platelet retention, platelet aggregation, platelet factor 3, and platelet volume profiles.
    • Identification and control of variables affecting assay reproducibility.
    • Determination of normal values in a large volunteer population.

    Main Results:

    • Established standardized protocols for multiple platelet function assays.
    • Defined normal value ranges for each standardized test.
    • Demonstrated the utility of these profiles in identifying disease states.

    Conclusions:

    • Standardized platelet function testing enhances diagnostic reliability.
    • Established normal ranges facilitate the identification of abnormal platelet function.
    • A comprehensive profile format aids in the assessment of hemostatic disorders.
