Part Descriptions

LP16487-8   Reticulocytes
Reticulocytes are immature red blood cells (RBC), comprising about 1% of the red cells in the human body. They develop and mature in the bone marrow and then circulate for about a day in the blood before developing into mature RBC. Like mature RBC, reticulocytes do not have a nucleus. They are called reticulocytes because of a reticular (mesh-like) network of ribosomal RNA that is visible under a microscope. Reticulocytes appear slightly bluer than other RBC when stained with Romanowsky stain. Reticulocytes are also slightly larger and thus can be identified as a high mean corpuscular volume during a full blood count done by machine.

LP16487-8   Reticulocytes
In humans, reticulocytes are erythroid cells that have just undergone extrusion of their nucleus. They still contain some organelles that gradually decrease in number as the cells mature. Ribosomes are last to disappear. Certain staining techniques cause components of the ribosomes to precipitate into characteristic "reticulum" (not the same as the endoplasmic retuculum), hence the name reticulocytes.

Change Reason

Release 2.79: COMPONENT: Triggered by Coll w SCT: This is a specific fraction case where the denominator is percentage or /100. Because the logic is that the percentage piece is captured by Property: NFr (Numeric Fraction), and by Unit: %, therefore, it is redundant to include "100" in the component; Previous Releases: The system of RBC had been an oversight. Reticulocytes are red blood cells, but the system of interest is blood Changed Order_Obs from 'Observation Only' to fit the current order use cases.
