检测灵敏度（Detection Sensitivity） 指系统或设备识别微弱信号、目标或变化的能力，是衡量检测精度与可靠性的核心指标。其数值越高，代表系统对微小变化的响应能力越强，在科学研究与工程应用中至关重要。
检测（Detection）
指通过传感器、仪器或算法识别特定目标（如生物标记物、物理信号、异常行为）的过程。例如，医学检测中识别早期癌细胞，或安防系统中发现异常入侵行为。
灵敏度（Sensitivity）
量化系统识别“真阳性”的能力，计算公式为：
$$text{Sensitivity} = frac{text{TP}}{text{TP} + text{FN}}$$
其中TP（True Positive） 为正确识别的目标数，FN（False Negative） 为漏检目标数。灵敏度越高，漏检率越低。
