The Utility of Immature Reticulocyte Fraction as an Indicator of Erythropoietic Response to Altitude Training in Elite Cyclists

open access: yesInternational Journal of Laboratory Hematology, 2010
SummaryAltitude training is sometimes employed by elite endurance athletes to improve their sea level performance. This improvement results from the increased red cell mass consequent upon the boost in erythropoietin (EPO) level that occurs as a response to the relatively hypoxic environment at high altitudes. We measured serum EPO levels together with

Reticulocyte Count, Mean Reticulocyte Volume, Immature Reticulocyte Fraction, and Mean Sphered Cell Volume in Elite Athletes: Reference Values and Comparison With the General Population

open access: yesClinical Chemistry and Laboratory Medicine, 2006
Abstract Background : The role of measurement of reticulocytes and their parameters is growing in sports medicine. The use of reticulocyte counts in protocols for evaluating and screening for the suspected abuse of hormones that stimulate the bone marrow is an example.

The Role of IRF (Immature Reticulocyte Fraction) in Pancytopenia

2021
Background: Pancytopenia is an important entity worldwide but with varying patterns in clinical presentations. Bone marrow aspiration and biopsy are considered as primary investigation to evaluate and diagnose the causes of pancytopenia. But before doing a bone marrow aspiration or biopsy, a note on the newer reticulocyte indices given by automated ...

Reference intervals of automated reticulocyte count and immature reticulocyte fraction in a pediatric population

International Journal of Laboratory Hematology, 2021
AbstractIntroductionReticulocytes are erythroid precursors that develop into mature erythrocytes, and they are an important tool to assess erythropoietic activity, as their count indicates the balance between the cells released from the bone marrow, their stage of maturity, and their rate of development into mature erythrocytes.

Immature Reticulocyte Fraction as a Useful Parameter for Blood Transfusion Assessment in Anaemia

British Journal of Biomedical Science, 2009
During erythropoietic stress (e.g., acute anaemia) the reticulocyte count in peripheral blood normally increases as the bone marrow responds to increased erythropoietin stimulation of erythroid precursors. The efficiency of this process is an indicator of the patient's bone marrow response.

Utility of reticulocyte haemoglobin content and immature reticulocyte fraction in early diagnosis of latent iron deficiency in whole blood donors

Vox Sanguinis, 2021
AbstractBackground and ObjectivesThe present study was planned to assess the clinical utility of reticulocyte haemoglobin content (CHr) and immature reticulocyte fraction (IRF) in the early detection of latent iron deficiency in blood donors.Materials and MethodsThe prospective longitudinal observational study was conducted using the purposive sampling

Effect of Hydroxyurea on Immature Reticulocyte Fraction in Sickle Cell Anemia

Laboratory Hematology, 2007
Immature reticulocyte fraction (IRF) is a good indicator of bone marrow erythropoiesis in response to hemolysis or tissue hypoxia and is markedly increased in sickle cell disease (SS). We compared IRF changes in SS patients with those who were treated with hydroxyurea (SS-HU), and those who had concurrent alpha globin gene deletion (SS-(- deletion ...

Novel Hematological Parameters for the Evaluation of Patients With Myeloproliferative Neoplasms: The Immature Platelet and Reticulocyte Fractions

Annals of Hematology, 2017
New automated hematology analyzers have led to the availability of novel hematological parameters, including the immature platelet fraction (IPF) and the immature reticulocyte fraction (IRF), both of potential interest in patients with myeloproliferative neoplasms (MPNs).

Assessment of immature platelet fraction and immature reticulocyte fraction as predictors of engraftment after hematopoietic stem cell transplantation

International Journal of Laboratory Hematology, 2014
SummaryIntroductionEngraftment is a critical milestone of the hematopoietic stem cell transplantation (HSCT) process. The immature platelet fraction (IPF) and immature reticulocyte fraction (IRF) are considered early indicators of bone marrow recovery.
