To aid with determining the underlying cause of the normocytic anemia, a lab test is done on reticulocyte count. [2] A reticulocyte count that is high, normal or low will aid with the classification process. A high reticulocyte count signifies that bone marrow processes are normal. A low reticulocyte count would signify there is a problem at ...
Reticulocytosis is a laboratory finding in which the number of reticulocytes (immature red blood cells) in the bloodstream is elevated. Reticulocytes account for approximately 0.5% to 2.5% of the total red blood cells in healthy adults and 2% to 6% in infants, but in reticulocytosis, this percentage rises. [1]
The problem arises because the reticulocyte count is not really a count but rather a percentage: it reports the number of reticulocytes as a percentage of the number of red blood cells. In anemia, the patient's red blood cells are depleted, creating an erroneously elevated reticulocyte count. [1]
Complete blood count and reticulocyte count; in active G6PD deficiency, Heinz bodies can be seen in red blood cells on a blood film; Liver enzymes (to exclude other causes of jaundice); Lactate dehydrogenase (elevated in hemolysis and a marker of hemolytic severity) Haptoglobin (decreased in hemolysis);
A reticulocyte percentage that is higher than "normal" can be a sign of anemia, but this depends on the health of a person's bone marrow. Calculating the reticulocyte production index is an important step in understanding whether or not the reticulocyte count is appropriate to the situation. This is often a more important question than whether ...
A reticulocyte count is sometimes performed as part of a complete blood count, usually to investigate the cause of a person's anemia or evaluate their response to treatment. Anemia with a high reticulocyte count can indicate that the bone marrow is producing red blood cells at a higher rate to compensate for blood loss or hemolysis, [74] while ...
If a low count of reticulocytes is found, it usually indicates bone marrow stress. If a high reticulocyte count is found, it is usually linked to hemolysis, but a Coombs test may be performed in this case to rule out immune-mediated hemolysis. [4] Polychromasia can also be seen in blood smears when there is a normal reticulocyte count.
For the patient with isolated reticulocytopenia and anemia without significant disturbances in other cell lineages, the initial evaluation may include some of the following studies: [7] Complete blood count with differential; Peripheral blood smear; Type and Cross (in case transfusion is needed) Reticulocyte Production Index
