The maximum normal range of white blood cells (WBCs) is 11,000 per microliter (µL).
Here's a more detailed breakdown:
-
Normal Range: Generally, a normal white blood cell count falls between 4,000 and 11,000 WBCs per microliter of blood.
-
Variations: This range can vary slightly depending on the laboratory and the specific testing method used. It can also differ based on age and pregnancy status. Children often have a wider normal range than adults, and pregnant women may have slightly higher WBC counts.
-
High WBC Count (Leukocytosis): A WBC count above 11,000/µL is known as leukocytosis. This can indicate an infection, inflammation, stress, or certain underlying medical conditions.
-
Low WBC Count (Leukopenia): A WBC count below 4,000/µL is known as leukopenia. This can be caused by infections, medications, autoimmune disorders, or bone marrow problems.
In summary, while the normal range fluctuates, a white blood cell count exceeding 11,000 per microliter is generally considered the upper limit of the normal range. Always consult with a healthcare professional for accurate interpretation of your blood test results.
