How is leukocytes calculated?
Count the number of both intact and disrupted WBCs in each of 10 microscopic fields in different areas of the slide where RBCs slightly overlap. Divide the total number by 10 to establish the mean number of WBCs/field and multiply this mean by 3,000 to get the estimated WBC count/mm³.
What is total leukocyte?
The full form of TLC is Total Leukocyte Count. TLC or WBC count is a blood test that evaluates the number of WBC (white blood cells), also known as leukocytes. The leukocytes are the essential parts of our defense mechanism as they fight with infections.

Reference (Normal) Range
| Example White Blood Cell (WBC) Count Reference Ranges | |
|---|---|
| Approximate Low Range | < 4,000 white blood cells per mm3 |
| Approximate Normal Range | 4,500-10,000 white blood cells per mm3 |
| Approximate High Range | > 10,000 white blood cells per mm3 |

Is a white blood cell count of 12.6 high?
The specific number for high (above normal) white blood cell count varies from one lab testing facility to another, but a general rule of thumb is that a count of more than 10,500 leukocytes in a microliter of blood in adults is generally considered to be high, while 4,500-10,500 is considered within the normal range.
