title: [Reference values of T-lymphocyte subsets in umbilical cord blood].
abstract: In order to determine reference values of T lymphocyte subpopulations in cord blood in the metropolitan area of Puebla city we randomly selected 80 from a total of 400 term, eutrofic and without pathology newborn. The percentage of CD3, CD4 and CD8 T lymphocyte subpopulations in cord blood were determined by flow cytometry. Reference values were gotten from the 25 and 75 percentile in parameters without gaussian distribution. Reference values are CD3 (45.5 to 91.3%), CD4 (26.2 to 69.4%), CD8 (16.2 to 24.1%) and NK (2.0 to 8.5%). The presented data represent valuable normal ranges of T lymphocyte subsets to compare with values observed in sick or in risk of developing immunoallergic pathology children.
