Clinical noticeEducational arithmetic aid only. This tool derives ALC from CBC differential inputs and does not replace direct laboratory reporting or clinician interpretation.

Context and use

ALC = total white blood cell count × (lymphocyte percentage / 100)

Equivalent values across ×10^9/L, ×10^3/µL, and cells/µL are normalized before the result is shown in the selected output unit.

Fixed interpretation cutoffs are intentionally omitted because reference intervals vary by age and laboratory.
