Nucleated erythrocytes/Erythrocytes in Blood by Manual count
Discouraged
Status Information

- DISCOURAGED
- 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.

Mapping Guidance | Regenstrief Help | Automated 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;
