	Reticulocyte count
		A reticulocyte count is usually performed when patients are evaluated for anemia and response to its treatment.

	Reticulocyte - Wikipedia, the free encyclopedia
		Reticulocytes are also slightly larger, which can be picked up as a high MCV (mean corpuscular volume) with a full blood count done by machine.
		The reticulocyte count is the percentage of circulating red blood cells that are in the reticulocyte stage.
		Reticulocytes increase in number and percentage when there is increased production of red blood cells such as in a haemolytic anaemia or sickle cell anemia.

	INTEGRATED CASE: HEMATOLOGY #1
		Reticulocytes are defined as immature red cells seen in the peripheral blood that contain at least two dots of reticulin material reactive with new methylene blue (NMB) in their cytoplasm.
		Reticulocytes are counted as the number of NMB-reactive cells per 1,000 red cells and expressed as percent reticulocytes (absolute number per 100 red cells).
		Interobserver variation and uneven distribution of reticulocytes on the new methylene blue smear introduces a high analytic variation in reticulocyte counting; interlaboratory coefficients of variation in the 20% range are common, a degree of imprecision of which every clinician should be aware.

	Medicare News Update, Issue 99-#8
		Reticulocytes are immature, anucleated RBCs containing remnants of ribonucleic acid (RNA), which appear as a dark blue network (reticulum) after incubation in new methylene blue or brilliant cresyl blue.
		The reticulocyte count is therefore usually corrected for the anemia by multiplying the measured percentage (reticulocyte count) by the ratio of the patient's hematocrit against a normal hematocrit to obtain the reticulocyte index.
		The reticulocyte count is commonly indicated in the evaluation of unexplained anemia and may be useful in the evaluation of response to therapeutic intervention.

	Reticulocyte Count: The Test
		The reticulocyte count is ordered to help determine if the bone marrow is responding adequately to the body’s need for RBCs and to help determine the cause of and classify different types of anemia.
		The number of reticulocytes must be compared to the number of RBCs to calculate a percentage of reticulocytes; thus, the test is ordered along with a RBC count.
		A reticulocyte count may be ordered when a patient has a decreased RBC count and/or a decreased hemoglobin and hematocrit and the doctor wants to evaluate bone marrow function.

	Reticulocyte Count - Good Health by SETON
		The reticulocyte count rises when there is a lot of blood loss or in certain diseases in which red blood cells are destroyed prematurely, such as hemolytic anemia.
		The reticulocyte count is given as the percentage of red blood cells that are reticulocytes (the number of reticulocytes divided by the total number of red blood cells, multiplied by 100).
		A reticulocyte count may help a doctor decide other tests that need to be done to diagnose a specific type of anemia or other disease.

	Diagnostic Edge - January 2004
		Reticulocytes are nonnucleated red blood cell precursors that typically do most of their maturation within the hematopoietic tissue of the bone marrow.
		Reticulocyte counts are valuable in determining if an anemia is regenerative (adequate bone marrow response) or nonregenerative (inadequate bone marrow response), as well as in identifying underlying occult compensated hemolytic processes.
		Reticulocytes with sufficient RNA in the cytoplasm can be identified in a peripheral blood film stained with a standard Romanovsky stain, including most quick stains used in practice.

	Anemias: Currents: UI Health Care
		The reticulocyte count is expressed as a percentage of total cells counted and must be corrected to a total number of reticulocytes per microliter.
		Reticulocyte counts that are normal or low (in the face of anemia) are suggestive of the inability of the bone marrow to respond to anemia (marrow failure).
		Reticulocyte hemoglobin content may be a more accurate reflection of bone marrow iron stores and is a promising technology.

	Anemia and aplastic
		True aplastic crisis with very low reticulocyte count and only anemia is usually seen in children and associated with infection by the parvovirus B19.
		When the anemia is stable and the reticulocyte count is at the patient’s normal level, discharge with less frequent monitoring is indicated.
		Hemoglobin levels, reticulocyte counts, indirect bilirubin, and LDH should be determined on a regular basis during health maintenance to establish a baseline for each patient which will usually be relatively stable.

		INDICATIONS and LIMITATIONS OF COVERAGE: The reticulocyte count is indicated in the evaluation of unexplained anemia and may be useful in the evaluation of the response to therapeutic intervention.

	Reticulocyte Count
		Reticulocytes circulate in the bloodstream for about 2 days before developing into mature red blood cells.
		The reticulocyte count increases during rapid blood loss or in the course of certain diseases in which red blood cells are destroyed prematurely.
		For example, a higher reticulocyte count indicates that iron replacement treatment or other treatment to reverse the anemia is effective.

	Reconstitution of the Steroid Receptor·hsp90 Heterocomplex Assembly System of Rabbit Reticulocyte Lysate -- Dittmar et ...
		The GR must be associated with hsp90 for it to bind steroid (8), and conversion of the GR to a steroid binding form constitutes a rapid assay for heterocomplex assembly (4, 9).
		Reticulocyte lysate was depleted of hsp70 by extraction of hsp70 onto a matrix of ATP-agarose exactly as described by Hutchison et al.
		The components of the rabbit reticulocyte receptor·hsp90 heterocomplex assembly system were identified by analyzing the proteins that were bound to the chicken progesterone receptor (PR) at early and late stages of assembly of the PR·hsp90 heterocomplex (10, 12, 14, 19).

	Reticulocyte Count in Cats
		A reticulocyte count is a measure of the number of reticulocytes circulating in the blood.
		In the presence of anemia, a low reticulocyte count indicates that the body does not recognize the anemia and is not trying to correct the situation.
		On the other hand, a high reticulocyte count indicates that the body does recognize the anemia and is responding by releasing the immature cells and “regenerating new cells”.

	Pathology
		An increased reticulocyte count indicates loss or destruction of RBCs, with an appropriate bone marrow response, as in hemorrhage or hemolysis.

	Reticulocyte hemoglobin detects iron deficit in infants American Family Physician - Find Articles (Site not responding. Last check: 2007-10-16)
		The authors of this study prospectively monitored 202 healthy infants nine to 12 months of age to compare reticulocyte hemoglobin content with hemoglobin in screening for iron deficiency.
		The optimal cutoff level for detecting iron deficiency with reticulocyte hemoglobin content was 27.5 pg (sensitivity = 83 percent; specificity = 72 percent).
		Bottom Line: A low reticulocyte hemogobin content has a higher sensitivity for the accurate detection of early iron deficiency in infants than a standard hemoglobin measurement.
