宏观检查（macroscopic examination）是指通过肉眼或低倍放大工具（如放大镜）对物体或样本进行整体形态、结构及表面特征的观察与分析。该方法广泛应用于医学、材料科学、地质学等领域，侧重于捕捉肉眼可见的宏观特征，而非依赖显微镜或分子级别的检测手段。
在医学领域，宏观检查是病理诊断的基础步骤。例如外科医生切除的肿瘤组织会首先记录其大小、颜色、质地及边界特征，这些观察结果可辅助判断病变性质。英国皇家病理学院（Royal College of Pathologists）的指南明确指出，规范的宏观描述是确保后续显微镜诊断准确性的关键环节（来源：rcpath.org）。
材料工程中，宏观检查用于评估金属铸件、焊接接头等工业制品的质量。美国材料与试验协会（ASTM）标准E3-11中规定，在进行金相分析前必须完成表面缺陷、裂纹分布等宏观特征的记录（来源：astm.org）。例如对断裂的机械部件进行断口形貌分析，可初步判断其失效模式属于疲劳断裂还是脆性断裂。
地质学家则通过岩石标本的宏观检查，识别矿物组成、层理构造等特征。美国地质调查局（USGS）的野外工作手册强调，岩石手标本的宏观观察是绘制地质图件的重要依据（来源：usgs.gov）。这种非破坏性检测方式具有快速、经济的特点，常作为进一步实验室检测的筛选手段。
"Macroscopic examination" 是一个科学和医学领域的术语，指通过肉眼或低倍放大工具（如放大镜）对物体、组织或样本进行观察和分析的过程。其核心在于评估整体结构、形态或表面特征，而非微观细节。以下是详细解释：
