Neutrophil to Lymphocyte Ratio 計算機 (NLR)
Neutrophil to Lymphocyte Ratio (NLR) = Absolute Neutrophil count / Absolute Lymphocyte count
炎症(感染)和生理壓力(如低血容量性休克)等的指標
Physiologic stress level (生理壓力水平)
– NLR < 3 : Normal (正常)
– NLR 3 ~ 6 : Borderline (邊界)
– NLR 6 ~ 9 : Mild stress (輕度壓力)
– NLR 9 ~ 18 : Moderate stress (中度壓力)
– NLR > 18 : Severe stress (重度壓力)

Effect of physiologic stress on NLR :
NLR的注意事項:
- 使用外源性類固醇時NLR可能增加。
- 在白血病、化療、使用G-CSF等情況下細胞計數可能發生變化。
- HIV患者的基本NLR可能增加。
