Test Overview

Test Methodology

Sysmex XN9000

Test Usage

The IPF (Immature Platelet Fraction) will be reflexed on any platelet that is below 150 K/uL.
The IPF is an early indicator of platelet production and typically elevated in disorders of platelet destruction, such as ITP, TTP, and DIC. It is also an early indicator of bone marrow recovery in post-chemotherapy and stem cell transplant patients. A decreased IPF is indicative of decreased platelet production in the bone marrow.

Reference Range

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
