Absolute Lymphocyte Count
- Sample Type
- Standard
- Fasting
- No
- Unit
- 10^3/µL
The Absolute Lymphocyte Count (ALC) measures the actual number of lymphocytes (T-cells, B-cells, and NK cells) per unit of blood. In COVID Panel Hematology, the ALC is a critical prognostic marker; lymphopenia (low ALC) is strongly associated with increased severity and poor outcomes in viral pneumonia, as it reflects the consumption or destruction of immune cells during the cytokine storm.

Why Context Matters
ALC can be affected by recent surgery, steroid use, or severe physical stress. In the absence of viral symptoms, a high ALC might be a benign reaction to a different infection or an early sign of a chronic lymphoproliferative disorder (like CLL), requiring specialized flow cytometry for confirmation.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
