Abstract
RODRIGUEZ ORDONEZ, FELIPE et al. CORRELATION BETWEEN NEONATAL AND MATERNAL PHYSICAL CHARACTERISTICS WITH TOTAL NUCLEATED CELL COUNT AND CELL COUNT PER MICROLITER CD34+ IN CORD BLOOD. rev.fac.med [online]. 2015, vol.23, n.2, pp.71-77. ISSN 0121-5256.
Background: The cord blood has been recognized as a source of hematopoietic stem. Multiple studies have been conducted in order to determine maternal and neonatal variables that affect the volume, total nucleated cell count and CD34+ cells. This study correlated maternal and neonatal variables with the total nucleated cell count and CD34+ cells measured by μL. Materials and methods: Correlational study in which 50 samples of umbilical cord blood were analyzed of pregnant women at two health institutions, one at Bogotá and the other one at Ubaté, Cundinamarca, for a period of seven months of 2013. The selection of these samples was based on a non-probability sample. The Pearson correlation coefficient was calculated with their respective statistical significance between quantitative variables of mother and newborn, and the volume, the count of CD34+ cells and the total nucleated cell count measured by μL. Results: Positive correlation between the length of the umbilical cord and the total nucleated cell count was found. Similarly, correlation between total nucleated cell count with the initial volume and count of CD34+ cells in μL and mL was found. Discussion: Several studies have been conducted around to look maternal and neonatal variables that affect the sample quality, however, the Colombian literature has not described the correlation found in this study, so it requires the development of new research with designs of analytical studies to establish associations between the variables described.
