Comment
None of the major national laboratories in the USA report nucleated RBCs per 100 or 1000 RBCs. They all report per 100 WBCs. Furthermore the automated counting instruments always produce the per WBC measures so they can report a WBC corrected for nucleated RBCs. So if you are mapping it is most likely that you don't want this term you want the map to term.

18309-5Nucleated erythrocytes/Leukocytes [Ratio] in Blood by Manual count

Part Description

LP14464-9   Erythrocytes.nucleated
Large numbers of nucleated erythrocytes are found in hemolytic disease of the newborn, leukemias,and chronic myeloproliferative disorders. Source: Regenstrief LOINC

Reference Information

TypeSourceReference
Mapping GuidanceRegenstrief HelpAutomated instruments measure per 100 WBCs rather than per 100 RBCs so they can correct the WBC. It is very UNLIKELY you will see many lab tests with the denominator of RBC's. So, be sure that you don't want to map to LOINC 58413-6.

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;
