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.

Reference Information

Type	Source	Reference
Mapping Guidance	Regenstrief Help	Reticulocytes are reported as percents (per 100) of RBC's even if based on a count of 1000 RBC's or more. So the right term for a manual count is LOINC 31112-6 regardless of the number of cells counted. However, today it is most likely that these are done by automated methods LOINC 17849-1, not manual methods. Mapper’s Guide for the Top 2000 plus LOINC Laboratory Observations

Basic Attributes

Class: HEM/BC
Type: Laboratory
First Released: Version 1.0l
Last Updated: Version 2.79 (NAM)
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.
Order vs. Observation: Both
