🩸 中性粒细胞绝对计数（ANC）计算器Absolute Neutrophil Count (ANC) Calculator
由血常规的白细胞总数和中性粒细胞百分比（分叶核 + 杆状核）计算中性粒细胞绝对计数 ANC，并按常用分级判断是否中性粒细胞减少。Calculate the absolute neutrophil count from the white blood cell count and the percentage of neutrophils (segmented + bands), and grade any neutropenia with the usual cut-offs.
使用说明与常见问题How-to & FAQ
「中性粒细胞绝对计数（ANC）计算器」是什么？What is the Absolute Neutrophil Count (ANC) Calculator tool?
由血常规的白细胞总数和中性粒细胞百分比（分叶核 + 杆状核）计算中性粒细胞绝对计数 ANC，并按常用分级判断是否中性粒细胞减少。Calculate the absolute neutrophil count from the white blood cell count and the percentage of neutrophils (segmented + bands), and grade any neutropenia with the usual cut-offs.
如何使用「中性粒细胞绝对计数（ANC）计算器」？How do I use the Absolute Neutrophil Count (ANC) Calculator tool?
在「中性粒细胞绝对计数（ANC）计算器」中，填写「白细胞总数 WBC」、「WBC 单位」、「分叶核中性粒细胞 %」、「杆状核中性粒细胞 %（可选）」等参数，结果会随输入实时计算并显示在下方。In the Absolute Neutrophil Count (ANC) Calculator: Fill in "White blood cell count (WBC)", "WBC unit", "Segmented neutrophils %", "Band neutrophils % (optional)"; results are recalculated instantly as you type.
ANC 怎么算？How is ANC calculated?
ANC = 白细胞总数 × (分叶核 % + 杆状核 %) ÷ 100。例如 WBC 5.0 × 10⁹/L（5,000/µL），中性粒细胞 60%，ANC = 3,000/µL。ANC = WBC × (segs % + bands %) ÷ 100. With a WBC of 5.0 × 10⁹/L (5,000/µL) and 60% neutrophils, ANC = 3,000/µL.
中性粒细胞减少怎么分级？How is neutropenia graded?
常用分级：≥ 1,500/µL 正常，1,000–1,499 轻度，500–999 中度，< 500 重度。重度时感染风险显著升高，发热应立即就医。The usual grades: ≥ 1,500/µL normal, 1,000–1,499 mild, 500–999 moderate, below 500 severe. Severe neutropenia carries a high infection risk, and a fever needs urgent care.
结果可以代替医生的建议吗？Can this replace medical advice?
不能。「中性粒细胞绝对计数（ANC）计算器」基于常用公式给出估算，个体差异较大，如有健康问题请咨询医生或专业人士。No. The Absolute Neutrophil Count (ANC) Calculator gives estimates from common formulas; individuals differ, so consult a doctor or professional for health decisions.
