Hematologic Example 2

This example simply records the workup and the values obtained in an abbreviated form. Abbreviations frequently used are:

  • CBC = complete blood count (RBC and WBC)
  • RBC = red blood count
  • WBC = white blood count
  • Hct. = hematocrit
  • Hgb. = hemoglobin
  • Plat. = platelets
  • Retic. = reticulocytes
  • PME = polymorphonuclear eosinophils (leukocytes)
  • PMN = polymorphonuclear neutrophils (leukocytes)

Polymorphonuclear leukocytes usually refer only to neutrophils. Notice in this example that the abbreviations PME and PMN are both used.

Promonocytes are immature monocytes.

Check that the differential white count adds to 100%

Leukocytes Percent
PMN 90
PME 1
Mature lymphocytes 3
Mature monocytes 5
Promonocytes 1
Total: 100%
