Some authors advice counting nucleated red blood cells
per 100 white blood cells because the placental counts correlate well with umbilical blood counts (1,89); however, that is not practical, and most authors use subjective (9) or semiquantitative (73) criteria to assess the number of nucleated red blood cells
Identification of fetal nucleated red blood cells
in the maternal circulation during pregnancy using anti-hemoglobin-epsilon antibody.
The Phase II grant is designed to optimize the enrichment of fetal nucleated red blood cells
and improve the system prior to commercialization.
The hematopoietic cells are comprised of nucleated red blood cells
, lymphocytes, monocytes, and neutrophils.
Nucleated red blood cells
were present at a rate of 32 per 100 white blood cells and revealed irregular nuclear contour and double nuclei (Figure 1).
The possibility of isolating fetal nucleated red blood cells
from maternal blood samples for use in antenatal diagnosis of fetal genetic or chromosomal abnormality has gained much attention in recent years (8, 9).
Review of the peripheral smear revealed notable red cell morphology (Figure 1) and 24 nucleated red blood cells
per 100 white blood cells, many of which were dysplastic.
The use of fetal cells, such as nucleated red blood cells
(NRBCs), has been attempted as a means of noninvasive prenatal diagnosis.
During the second quarter, the Company received 510(k) clearance for its WINSCAN(TM) Automated Imaging System for the identification and enumeration of nucleated red blood cells
from peripheral blood.
Q Our lab recently purchased a cell counter that will enumerate nucleated red blood cells
(nRBCs) and report a corrected white blood cell count (WBC) if the size of the nRBCs is at the threshold for triggering a cellular interference flag.
Fetal nucleated red blood cells
(NRBCs)  are good candidates for the purpose of prenatal diagnosis for several reasons.
Food and Drug Administration (FDA) to market its WINSCAN(TM) Automated Imaging System for the identification and enumeration of nucleated red blood cells
from peripheral blood.
Using fluorescent flow cytometry and advanced cell-counting methods, the XE-2100 Series provides a complete blood count (CBC) with an extended differential that includes automatic enumeration of nucleated red blood cells
and haematopoietic progenitor cells.
