🩸 Absolute Lymphocyte Count (ALC)
UseWhen to use: CBC without an auto-absolute lymphocyte field, or teaching.
StrataRough adult bands ~1–4 ×10⁹/L; interpret with clinical context.
LimitsWhen not to use: if lab already reports ALC — prefer that. · Pitfall: mixing /µL vs ×10⁹/L. · Steroids/HIV/CLL change norms.

How it works
ALC = WBC × (lymphocyte%/100).

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| WBC | 6.5 ×10⁹/L |
|---|---|
| Lymphocytes | 30 % |
→ALC1.95×10⁹/L
- Cue：~1.0–4.0 — common adult reference-ish band
- Also：1950 /µL

FAQ
Frequently asked questions
- Does Absolute Lymphocyte Count (ALC) upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is Absolute Lymphocyte Count (ALC) calculated in practice? Can you show a worked example?
- Inputs: WBC 6.5 ×10⁹/L, Lymphocytes 30 % → Result: ALC 1.95 ×10⁹/L（Cue: ~1.0–4.0 — common adult reference-ish band, Also: 1950 /µL）
