The immature platelet fraction (IPF) in neonates
Thrombocytopenia occurs in 30% of all neonates admitted to intensive care. Young, immature platelets containing RNA, measured as “immature platelet fraction” (IPF) on Sysmex analyzers, can help to assess platelet production. Thus, they allow conclusions on both the etiology and the likely course of thrombocytopenia in neonates.
