The platelet count and mean platelet volume

    Summary
    This summary is machine-generated.

    The Coulter Model S-Plus Counter reveals an inverse relationship between platelet count and mean platelet volume (MPV). Normal adults typically have 150-450 X 10(9)/l platelets with an MPV of 7.0-10.5 fl.

    Area of Science:

    • Hematology
    • Clinical Pathology

    Background:

    • Platelets are crucial for hemostasis.
    • Mean Platelet Volume (MPV) is an indicator of platelet activation and production.
    • The Coulter Model S-Plus Counter is a standard hematology analyzer.

    Purpose of the Study:

    • To investigate the relationship between platelet count and MPV in a large cohort.
    • To establish reference ranges for platelet count and MPV in normal adults.
    • To explore variations in platelet parameters in various clinical conditions.

    Main Methods:

    • Analysis of 5000 unselected blood specimens using the Coulter Model S-Plus Counter.
    • Statistical analysis to determine the correlation between platelet count and MPV.
    • Comparison of platelet parameters in different patient groups (e.g., pregnancy, anemia, infection).

    Main Results:

    • An inverse relationship was observed between platelet count and MPV.
    • Normal adult reference ranges: platelet count 150-450 X 10(9)/l, MPV 7.0-10.5 fl.
    • Thrombocytosis noted in iron deficiency anemia, trauma, blood loss, and rheumatoid arthritis.
    • Lower platelet counts and larger MPV observed in pre-eclampsia and hypertension during late pregnancy.
    • Variable platelet patterns seen in infection, renal failure, and treated malignant disease.

    Conclusions:

    • Platelet count and MPV exhibit an inverse correlation.
    • Established reference ranges aid in diagnosing platelet-related disorders.
    • MPV variations can indicate underlying pathological conditions, including pregnancy complications and inflammatory states.
