MANUAL WHITE BLOOD CELL COUNT FORMULA
Calculate the total white blood cells count by the help of Neubauer Chamber/Hemocytometer. of cells counted = N = 150(Assumption) Region which is Counted = 1 mm2 x 4 = 4 mm2 (Region of 4 big corner squares) Deepness = 1/10 mm. Dilution Mixture = 1:20. Therefore White Blood Cells/Cubic mm of Whole Blood = N x 50 = 150 x 50 = 7,500

Manual Cell Counting With Neubauer Chamber
General Features of The Neubauer’s ChamberCell Counting Areas in Neubauer ChamberUsing The Neubauer ChamberCalculating The Cell CountsNeubauer’s chamber is a thick glass plate with the size of a glass slide (30x70x4mm). The counting region consists of two square shaped ruled areas. There are depressions or the moats on either side or in between the areas on which the squares are marked thus giving an “H” shape ruled area is 3mm2 divided into 9 large squares each with a 1 mm2 area. The large central square (which can be seen in its entirely with the 10X objective), is divided into 25 medium squares with double or triple..See more on laboratoryinfo[PDF]
WBC manual count using hemocytometer
Whole blood collected in EDTA is diluted according to the type of cell count obtained. The diluted blood suspension is then placed in a chamber and the cell counted. The count is multiplied by dilution factor and reported as number of cells per microlitter (µL) of whole blood.

How to perform Manual Differential Count | Medical
If the smear is acceptable, estimate the white cell count by counting the number of WBC in each of 5 or 6 low power fields. Average the numbers. Multiply the average by 1000 and divide by 4.

If it is estimated that there is >10% eosinophils or >5% basophils then a manual differential should be performed. For manual differential count at least 100 white blood cells under high dry lens using the LIS keyboard. Alternatively, differential may be done under oil immersion lens.
How to Calculate the Corrected WBC Count | Sciencing
Apr 30, 2018The total number of white blood cells (WBC) in a blood smear is called a WBC count. When you conduct a WBC count, you actually receive a total that includes both WBCs and nucleated red blood cells. Nucleated red blood cells are the precursors to normal red blood cells and look very similar to WBCs.
WBC counts | eClinpath
The white cell count (WBC) is the total number of leukocytes in a volume of blood, expressed as thousands/µL. As with the RBC, the WBC can be done by manual methods or by automated cell counters. The WBC by any method is a count of nuclei or total nucleated cell count.
