Clinical Significance
The IPF measures the most immature platelet forms with high nucleic acid content. IPF results may be used to evaluate thrombocytopenic
patients caused by peripheral destruction or insufficient marrow production of platelets. Additionally, IPF may be used to evaluate
platelet production in patients receiving chemotherapy and/or platelet engraftment in hematopoietic stem cell transplant recipients.
An elevated IPF suggests that platelets are being formed, which can mitigate the need for platelet transfusion depending on the clinical
situation.
