A leukocyte count, also known as a white blood cell (WBC) count, is a blood test that measures the number of white blood cells in your blood. White blood cells, or leukocytes, are a crucial part of your body's immune system, fighting off infections and diseases. This simple, widely available, and inexpensive test provides valuable information about your overall health.
Understanding Leukocyte Function
White blood cells are responsible for protecting your body from infection. They circulate throughout your body, identifying and eliminating harmful substances like bacteria, viruses, and fungi. Different types of white blood cells perform specific roles in this process. (White Blood Cells: Types, Function & Normal Ranges, White blood cell - Wikipedia)
Normal Leukocyte Count Ranges
A normal leukocyte count typically falls within the range of 4,500 to 11,000 WBCs per microliter (4.5 to 11.0 × 109/L). However, slight variations in normal ranges may exist depending on the laboratory and individual factors. (WBC count Information | Mount Sinai - New York, WBC count)
Interpreting Leukocyte Count Results
- High Leukocyte Count (Leukocytosis): An elevated WBC count may indicate an infection, inflammation, or certain types of cancer. (Leukocyte count and coronary heart disease: implications for risk ..., The Leukocyte Count as a Predictor of Myocardial Infarction | New ...)
- Low Leukocyte Count (Leukopenia): A low WBC count can suggest a weakened immune system, bone marrow problems, or certain types of infections or medication side effects.
It's crucial to remember that a leukocyte count alone doesn't provide a definitive diagnosis. A healthcare professional will interpret the results in conjunction with other clinical findings and medical history to determine the appropriate course of action.

Leukocyte Count: Clinical Significance
The leukocyte count is a valuable tool in diagnosing and monitoring various health conditions. Its significance stems from its ability to reflect the body's response to infection and other inflammatory processes. For example, a persistently elevated WBC count might warrant further investigation for conditions such as cardiovascular disease. (Leukocyte Count as a Predictor of Cardiovascular Events and ...)
