We demonstrate proof-of-concept for point-of-care assessment of long-term alcohol consumption by measuring phosphatidylethanol in blood/dried blood spots with nano-electrospray ionization and MS/MS using a miniature mass spectrometer. 'Abstinence', 'moderate', and 'chronic' consumption could be distinguished rapidly for both sample types, and quantitative performance was obtained with blood (LoQ-100 ng mL).
我们通过使用微型质谱仪,以纳喷雾离子化和 MS/MS 的方式,在血液/干血斑中测量磷脂酰乙醇,从而证明了即时检测长期酒精摄入的概念验证。对于这两种样本类型,都可以快速区分“禁欲”、“适度”和“慢性”摄入,并且血液中可获得定量性能(LoQ-100ng/mL)。
