What This Value Measures
Leukocytes are the white blood cells and an important part of the immune system. Their count provides information about the body's defense status.
Elevated Value
An elevated level may indicate an infection, inflammation, or intense physical exertion.
Low Value
A decreased level may indicate certain viral infections, medication effects, or impaired blood formation.
Reference ranges are typical guide values for adults and vary depending on the laboratory, measurement method, age and sex — always compare with the range stated on your own report. A value outside the range does not automatically mean an illness, and a value within the range does not rule one out. The trend and overall picture are usually more informative than a single value. The doctor's assessment is always decisive.
