Total cell count < 1,000/?L = white blood cells (WBC) + non-WBC (e.g. mesothelial cells). Traditionally, body fluid counts are performed by manual counting of RBC and nucleated cells/WBC under a microscope using a haemocytometer (also referred to as 'counting chamber'). The WBC count should be verified by a Unopette hemocytometer procedure.

These components can also be counted under the microscope on a glass slide by a trained laboratory technician or a doctor and referred to as the manual WBC differential. The corrected WBC count equals the uncorrected WBC count multiplied by 100, and this total divided by the number of nucleated red blood cells added to 100. You can manually count the WBCs by diluting the blood in a diluting chamber, and then analyzing the smear in a hemocytometer.
