reticulocyte

 [rĕ-tik´u-lo-sīt″]
a young erythrocyte showing a basophilic reticulum under vital staining.

re·tic·u·lo·cyte

(re-tik'yū-lō-sīt'),
A young red blood cell containing a basophilic cytoplasmic network precipitated by brilliant cresyl blue representing residual polyribosomes; such cells become more numerous during the process of active blood regeneration.
See also: erythroblast.

reticulocyte

(rĭ-tĭk′yə-lō-sīt′)
n.
An immature red blood cell that contains a network of basophilic filaments.

re·tic′u·lo·cyt′ic (-sĭt′ĭk) adj.

re·tic·u·lo·cyte

(rĕ-tik'yū-lō-sīt)
A young erythrocyte that contains no nucleus but has residual RNA. The RNA can be visualized as granules or filaments when the cell is stained supravitally with new methylene blue. Normally, new red cells are released from the bone marrow to the peripheral blood as reticulocytes. They mature, losing the filamentous RNA in about 2 days. Reticulocytes comprise about 1% of circulating red blood cells. Increased concentrations are associated with hemolytic anemia and blood loss. Decreased concentrations are associated with ineffective erythropoiesis, aplastic anemia, and hypocellularity of erythroid precursors in the bone marrow.

reticulocyte

An immature red blood cell (ERYTHROCYTE) that contains a network that can be stained blue with basic dyes. Reticulocytes appear in the circulation at times of increased red cell formation.

Reticulocyte

An early, immature form of a red blood cell. Over time, the reticulocyte develops to become a mature, oxygen-carrying red blood cell.

Reticulocyte count [%] = Number of reticulocytes in "n" fields x 100 (9) [Number of fields ("n") x Average number of red cells per field]
Our patient also had a high reticulocyte count, which may have made the inclusions more abundant and therefore more obvious in the film.
Absolute reticulocyte count is a calculated index using the values generated from the reticulocyte count percentage and RBC count from the full blood count.
Conventionally, the reticulocyte count is used to provide information on the marrow response in anemic patients.
In addition, it is notable that the reticulocyte count was very low during treatment with SOF/RBV in this case (Figure 4).
In anti-RhD isoimmunization, there is the typical inverse relationship between reticulocyte count and hemoglobin, which is not characteristic of anti-Kell isoimmunization [12].
The physician then ordered a repeat CBC which included reticulocyte indices and a reticulocyte hemoglobin, a peripheral blood smear review, and iron studies.
To differentiate between intramedullary and peripheral hemolysis, it may be helpful to measure the reticulocyte count and lactate dehydrogenase, as a lack of elevation in reticulocyte count and high LDH is more consistent with intramedullary hemolysis.
There were no statistically significant differences in the mean hemoglobin level, mean MCV, mean serum TIBC, mean reticulocyte count, and mean ZPP (P > 0.05) between the two groups but the values of serum iron and serum ferritin were significantly higher in transfused patients than that in nontransfused patients (P < 0.0000001).
A test panel based on the haematological parameters of FBC and CHr (as part of the reticulocyte count) costs approximately ZAR220.00.
Though anemia during Trypanosoma cruzi is not accompanied by a decrease in reticulocyte numbers, similar to our findings, chemical inhibition of nitric oxide or treatment with anti-TNF did not rescue mice from anemia even though these treatments resulted in increased numbers of reticulocytes and suppressed decreases in bone marrow erythroblast numbers during infection.
This significant increase in [Hb.sub.mass] was also associated with an increase in reticulocyte count and Hct, compared with the CONTROL group, within the first two weeks of the LHTH altitude exposure.
