A model-based method of inspecting a specimen for presence of one or more artifacts (e.g., a clot, bubble, and/or foam). The method includes capturing multiple images of the specimen at multiple different exposures and at multiple spectra having different nominal wavelengths, selection of optimally-exposed pixels from the captured images to generate optimally-exposed image data for each spectra, computing statistics of the optimally-exposed pixels to generate statistical data, identifying a serum or plasma portion of the specimen, and classifying, based on the statistical data, whether an artifact is present or absent within the serum or plasma portion. Testing apparatus and quality check modules adapted to carry out the method are described, as are other aspects. 种针对个或多个伪像(例如凝块、气泡和/或泡沫)的存在来检验试样的基于模型的方法。所述方法包括以多个不同的曝光并且以具有不同标称波长的多个光谱来捕获试样的多个图像，从捕获的图像中选择最优曝光的像素来针对每个光谱生成最优曝光的图像数据，计算最优曝光的像素的统计量以生成统计数据，标识试样的血清或血浆部分，以及基于所述统计数据来对如下进行分类：伪像是存在还是不存在于血清或血浆部分内。描述了被适配成实施所述方法的测试装置和品质检查模块，如其它方面那样。
