Calculates ANC from WBC, neutrophil percentage, and bands with neutropenia severity grading

The Absolute Neutrophil Count (ANC) calculation is critical for evaluating immunocompromise, determining infection risk, and managing chemotherapy-related neutropenia in pediatric oncology patients. By combining the percentage of neutrophils and bands with total white blood cell count, clinicians can identify severe neutropenia (ANC <500) requiring protective measures or growth factor support. This calculation is essential in hematologic malignancies, bone marrow transplantation, and immune-related conditions.
