Interpretation:

Reticulocyte Hemoglobin Equivalent (RET-He):The measurement of reticulocyte hemoglobin content is a direct assessment of the incorporation of iron into erythrocyte hemoglobin and thus a direct estimate of the functional availability of iron into the red blood cell. Low values indicate inadequate iron supply relative to demand. Referenced from: Brugnara, C., Schiller, B., Moran, J. (2006). Reticulocyte hemoglobin equivalent (Ret He) and assessment of iron-deficient states, Clinical Laboratory Hematology, 18:303-308.

Units:

%

Interpretation:

The Immature Platelet Fraction (IPF) is an index of thrombopoiesis and can help to determine the mechanism of thrombocytopenia. An increased IPF in the presence of thrombocytopenia is indicative of a platelet destruction or consumption condition. Values at or below this range in combination with thrombocytopenia are indicative of decreased marrow production.

Specimen Requirements:

3.0 mL blood in a LAVENDER top vacutainer, collected within 24 Hrs of testing.

Pediatric Specimen Requirements:

0.5 mL in a 0.5 mL LAVENDER top tube, collected within 24 Hrs of testing.

Reference Range:

1.0 to 7.5%

Synonyms:

IPF, Reticulated Platelet
