Quick summary
WBC count reflects immune cell levels and is often reviewed with a differential.
WBC measures the number of white blood cells in your blood.
To evaluate immune response or inflammation.
This information is general and not a diagnosis.
Typical reference range: 4 - 11 thousand/uL
Reference ranges may vary slightly by laboratory.
Low WBC may be associated with reduced immune cell production. It can be seen with certain medications or viral illnesses.
A result within the reference range is generally considered typical. Interpretation depends on symptoms and other tests.
High WBC may be associated with infection, inflammation, or stress responses. It can be seen with recent illness or corticosteroid use.
These summaries are educational shorthand. Doctors still compare the full panel, symptoms, medicines, and the lab's own range.

Theme hubs are useful when this result makes more sense as part of a liver, lipid, blood-cell, iron, or kidney-style pattern. If you have several numbers from the same group, you can enter them together there.
Start with CBC-style markers such as hemoglobin, WBC, hematocrit, MCV, and RDW when the question is about blood cell patterns.
