This study found no significant differences in lymphocyte subsets (T, B, NK cells) or absolute counts based on age, gender, or sample origin in healthy blood donors. Reference ranges were established for laboratory use.

Area of Science:

  • Immunology
  • Hematology

Context:

  • Establishing normal reference ranges for lymphocyte subsets is crucial for accurate clinical interpretation.
  • Flow cytometry is a standard method for enumerating lymphocyte populations.
  • Variations in lymphocyte counts can be influenced by demographic factors.

Purpose:

  • To determine normal values for lymphocyte subsets (T, B, NK cells) in healthy individuals.
  • To investigate potential demographic influences (age, gender, origin) on lymphocyte subset distribution.
  • To compare absolute lymphocyte counts obtained via flow cytometry and automated cell counters.

Summary:

  • A prospective study of 100 blood donors analyzed lymphocyte subsets using direct immunofluorescence and flow cytometry.
  • No significant differences were observed in lymphocyte subset counts concerning age, gender, or sample origin.

  • Absolute lymphocyte counts from flow cytometry and automated cell counters showed no significant discrepancies.

    • Impact:

    • Provides established reference ranges for lymphocyte subsets in a healthy population.
    • Demonstrates the reliability of flow cytometry for lymphocyte enumeration compared to automated counters.
    • Highlights the lack of significant demographic influence on key lymphocyte populations.
