Complete Blood Count: Absolute or Relative Values?

Figures

Figure 1. Pythagorean theorem.

Figure 2. Error in the absolute basophil counts. This error is thereby proportional to the error in the total cell count (r = 0.8). E-check hematology quality control (QC level 3) is used on a Sysmex XE 5000 hematology analyzer.

Figure 3. Error in the absolute basophil counts. This error is thereby proportional to the error in the total cell count. E-check hematology quality control (QC level 1) is used on a Sysmex XE 5000 hematology analyzer.
