Normal range: 7.8 " “11.0 fL.
Use

Interpretation
Increased In
Hypothyroidism
Myeloproliferative neoplasms
All cases of accelerated bone marrow production of platelets (immune thrombocytopenias, postchemotherapy)

Decreased In
Disorders associated with decreased platelet production
In some patients with sepsis
In some patients with inherited thrombocytopenias, such as Wiskott-Aldrich syndrome
Limitations
