Conversion of Alternative Absolute Lymphocyte Count Units

  • This Lymphocyte Depletion Kinetics tool assumes entered values are measured using the International System (SI) of Units: i.e., absolute lymphocyte count value measured in units of 109 cells/liter
  • Users of the Lymphocyte Depletion Kinetics Tool must ensure that lab results are converted and entered into the tool using the proper (SI) units - entering data measured in other than SI units will yield invalid results.
  • Peripheral blood lymphocyte count results may be reported by some laboratories using other units.
  • The table below shows the equivalence between values/measurements provided by different commercially available hematology analyzers.
