Comparing absolute and proportional leucocyte differential counts reveals significant disparities, especially in abnormal samples. Absolute counts are suggested to offer superior diagnostic support for clinical laboratory analysis.

Area of Science:

  • Hematology
  • Clinical Pathology
  • Laboratory Medicine

Background:

  • Leukocyte differential counts are crucial in diagnosing various medical conditions.
  • Reporting methods for these counts include absolute (cells x 10^9/L) and proportional (percentage) values.
  • Discrepancies between these reporting methods can impact diagnostic interpretation.

Purpose of the Study:

  • To compare absolute and proportional leukocyte differential counts.
  • To evaluate the significance of disparities between the two reporting methods.
  • To determine which reporting method offers better diagnostic support.

Main Methods:

  • Analysis of stained blood films to obtain both absolute and proportional leukocyte counts.
  • Statistical comparison of results from the two methods.

  • Evaluation of disparities within and outside established reference intervals.

    • Main Results:

    • Significant disparities were observed between absolute and proportional leukocyte differential counts.
    • Disparities were modest within reference intervals but became significant in cases with distributional abnormalities.
    • The choice of reporting method influences the interpretation of results.

    Conclusions:

    • Absolute leukocyte counts are more likely to provide reliable diagnostic support compared to proportional counts.
    • Understanding the disparities between reporting methods is essential for accurate clinical interpretation.
    • Further standardization in reporting leukocyte differential counts may be beneficial.
