Absolute neutrophil count
Converts the white-cell differential to absolute neutrophils, a basis for defining febrile neutropenia, adjusting chemotherapy and assessing infection risk.
Calculate with transparency
Check the population, units and version. The result shows the formula or classification; it does not make an automatic treatment decision.

Method · Limits of application
ANC: leukocytes×(segmented+bands)/100; IDSA 2010 update/published 2011 context
The IDSA 2010/2011 reference addresses fever and chemotherapy-induced neutropenia in patients with cancer, with stratification depending on signs/symptoms, cancer, therapy and comorbidities. The calculated absolute count does not replace that assessment. The definition’s thresholds and units must be checked in the full guideline; the abstract read does not provide them.
Conditions of use
Check the population, units, inclusion and exclusion criteria, and version in the original source. A result alone does not establish a diagnosis, discharge decision or prescription.
Documented parameters
- Total white blood cell count · /µL
- Segmented neutrophils · %
- Band neutrophils (optional) · %
5/5 reference cases checked. Numerical tests are not clinical validation.
Relationship with cancer research
Support for research — context required
Neutrophil quantification that may support the description of hematological toxicity. Classification and management depend on the protocol, population and clinical assessment.
Applications: Adverse effects and safety
Immunology
ANC was a hematological variable monitored in 157 patients with advanced NSCLC treated with nivolumab/pembrolizumab (Soyano et al., 2018). This tool provides only the absolute count from the white blood cell count and differential; it does not calculate NLR or survival models, or determine the benefit of immunotherapy.
