[Standardization of ADP-induced thrombocyte aggregation]

H von Voss, C Petrich, J Tomaschoff

    Blut
    |August 1, 1976
    PubMed
    Summary

    Standardizing platelet aggregation tests is crucial for accurate results. Plasma samples require consistent temperature and timely analysis within two hours of collection for reliable platelet function assessment.

    Area of Science:

    • Hematology
    • Biochemistry

    Context:

    • Platelet aggregation is a key indicator of platelet function.
    • Standardization of laboratory methods is essential for reliable diagnostic and research outcomes.

    Purpose:

    • To standardize platelet aggregation testing using Born's method.
    • To identify critical pre-analytical factors influencing platelet aggregation measurements.

    Summary:

    • Platelet aggregation is significantly affected by plasma storage time, pH, and temperature.
    • No significant correlation exists between platelet count and aggregation in healthy individuals.
    • Reproducible results necessitate sample analysis within 2 hours of venipuncture and constant storage temperature.

    Impact:

    • Establishes critical parameters for accurate platelet function testing.
    • Provides guidelines for sample handling to improve the reliability of platelet aggregation assays.
    • Contributes to the standardization of hematological laboratory procedures.
