A vibrational spectroscopy method for diagnosing Alzheimer's disease in a subject is disclosed, said method comprising the steps of a) determining in a Raman spectrum of a biofluid retrieved from said subject or in a sample derived from said biofluid the intensity of a Raman band around 1256 cm-1; and b) comparing the intensity value obtained in step a) with a reference value, wherein an increase in the value of said Raman band intensity with respect to the reference value is indicative that the subject suffers Alzheimer's disease. Also disclosed are an apparatus for plasma sample analysis, a computer program, and a data carrier.
本发明公开了一种用于诊断受试者阿尔茨海默病的振动光谱学方法,所述方法包括以下步骤:a) 在从所述受试者身上提取的
生物流体的拉曼光谱中或在从所述
生物流体提取的样品中确定 1256 cm-1 附近的拉曼带的强度;以及 b) 将步骤 a) 中获得的强度值与参考值进行比较,其中所述拉曼带强度值相对于参考值的增加表明受试者患有阿尔茨海默病。还公开了一种用于血浆样本分析的仪器、计算机程序和数据载体。
