Relationships between platelet function tests in normal and uraemic subjects.

A A Hassanein, G P McNicol, A S Douglas

    Journal of Clinical Pathology
    |July 1, 1970
    PubMed
    Summary

    In normal individuals, higher platelet adhesiveness correlates with reduced adenosine diphosphate (ADP) disaggregation. Uraemic patients showed disrupted platelet function correlations.

    Area of Science:

    • Hematology
    • Clinical Biochemistry
    • Nephrology

    Background:

    • Platelet function is crucial for hemostasis.
    • Uremia is known to affect various physiological processes, including coagulation.

    Purpose of the Study:

    • To investigate the relationships between platelet adhesiveness, adenosine diphosphate (ADP)-induced disaggregation, and platelet factor 3 availability in normal subjects.
    • To determine if these relationships are altered in patients with uremia.

    Main Methods:

    • Assessing platelet adhesiveness.
    • Measuring platelet disaggregation after challenge with adenosine diphosphate (ADP).
    • Evaluating platelet factor 3 availability through clotting time.

    Main Results:

    • A negative correlation was observed between platelet adhesiveness and ADP-induced disaggregation in normal subjects.
    • A positive correlation was found between ADP-induced disaggregation and clotting time for platelet factor 3 availability in normal subjects.
    • These correlations were significantly disturbed in uraemic patients.

    Conclusions:

    • Established relationships between key platelet function parameters in normal individuals were identified.
    • Uremia disrupts the normal interplay between platelet adhesiveness, ADP-induced disaggregation, and platelet factor 3 availability, indicating impaired platelet function.
