Erythrocytes.fetal/Erythrocytes [Ratio] in Blood by Flow cytometry (FC)

Active

Term Description

The fetal RBC percentage is directly measured by flow cytometry.

Part Description

LP62759-3 Erythrocytes.fetal
Fetal red cells contain fetal hemoglobin (also hemoglobin F, HbF, or α2γ2) that is the main oxygen transport protein in the human fetus during the last seven months of development in the uterus and persists in the newborn until roughly 6 months old. Functionally, fetal hemoglobin differs most from adult hemoglobin in that it is able to bind oxygen with greater affinity than the adult form, giving the developing fetus better access to oxygen from the mother's bloodstream. In newborns, fetal hemoglobin is nearly completely replaced by adult hemoglobin by approximately 6 months postnatally, except in a few thalassemia cases.[Wikipedia] Copyright Text is available under the Creative Commons Attribution/Share-Alike License.

Basic Attributes

Class: HEM/BC
Type: Laboratory
First Released: Version 2.27
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: Changed Order_Obs from 'Observation Only' to 'Both' to fit current order use cases.
Order vs. Observation: Both
Common Test Rank Get Info: 6143
