Experimental methods
histopathology assay
What this technique is
- Category
- Histopathology
- Principle
- A histological assay that is intended to check for the presence or level of a specific disease.
- Input samples
- aorta · tissue · brain tissue sections
- Research questions
- Not provided
- Output and readout
- 输出为图像层面的疾病程度度量（如病变面积），采样对象、放大或成像条件与判读随所采用的具体实验方案确定。
- Applicability
- 通过组织或器官标本及其图像判断特定病变是否存在与其程度，包括主动脉 en face 斑块面积和脑组织 TTC 染色后的病变面积评价。取材、染色及面积计算采用对应具体方案。
- Limitations
- 方法概念本身不提供分级阈值或统计判读标准；结果有效性依赖所采用方案规定的标定、采样与复核规程。
