Notes

  • Immature Granulocytes count (IG): The IG count (% and #) includes metamyelocytes, myelocytes and promyelocytes.  Immature granulocytes are neutrophil precursors and their presence indicates a granulocytic left shift in the blood.  Preliminary studies have indicated that the automated IG count shows promise as an early screen for infection.1  The ability to provide a more accurate and precise automated immature granulocyte count without performing a manual differential will decrease turnaround times to provide patient results sooner.

 

  • Immature Platelet Fraction (IPF):  The Immature Platelet Fraction is an index of thrombopoiesis and it may assist the physician in determining the cause and differential diagnosis of thrombocytopenia when used with patient information and the platelet count.  IPF may help the physician determine if thrombocytopenia is due to platelet destruction or decreased platelet production.4
