Reticulocyte Count

R_ are young erythrocytes that have matured enough to have lost their nuclei but not their cytoplasmic RNA; they do not have the full amount of hemoglobin

Answer explanation

the more mature the reticulocyte is, the greater is the ribosomal content of the cell

The number of reticulocyte is a measure of the regeneration or production of r_

reticulocytes appear in a wright-stained blood film as p_ r_ because of the basophilic cytoplasmic remnan of the immature erythrocyte RNA

in the circulating blood, how many percent of the RBCs are actually reticulocytes?

this is based on the average RBC life span of _ days with replacement of approximately 1% of the adult circulating erythrocytes each day.

r_ is a reticulocyte count above normal level; a clinical indication that the body is attempting to meet an increased need for RBCs

Answer explanation

an increase in reticulocytes is observed when RBCs are being hemolyzed in the body

increased reticulocyte counts (reticulocytosis) and p_ are characteristic of a hemolytic condition, subsequent to blood loss, treatment of anemia, or other causes

Answer explanation

the demand for RBCs may be so great that in some patients, nucleated erythrocytes are prematurely released from the bone marrow

what are the specimen requirements for reticulocyte count?

• anticoagulated whole blood or capillary blood from the finger, toe, or heel

• venous blood should be anticoagulated with EDTA

• heparinized blood

if anticoagulated whole blood is used, the test should be performed within - to - hours after the specimen is drawn beacause cells will continue to mature in the tube, resulting in a decreased percent of reticulocytes seen

RNA content can be detected in reticulocytes by exposing the living cells to a s_ s_

Answer explanation

in supravital staining, the living blood cells are mixed with the stain, as opposed to making a film and staining it

which stains are used for the staining of reticulocytes?
