Current clinical diagnostics are based on biochemical, physics and microbiological methods. The electronic nose system used to detect chemical components or VOCs in urine sample is meant to classify different urine components so as to be able to diagnose diseases and other elements accurately. This study used urine sample from 13 patients from Universiti Teknologi Malaysia (UTM) health centre for the urine analysis. Findings from the study revealed that six patients tested abnormal with mucus while only one patient tested abnormal with bacteria and two healthy. The test conducted from using Cyranose 320 shows that volatile compounds were present in their urine. Principal component analysis (PCA) was used to extract first and second principal components from 32 sensors used for the urine analysis. The study suggests the possibility of using e-nose as an early detection system for illness such as diabetes and bacterial infections.

目前的临床诊断是基于生化、物理和微生物学方法。电子鼻系统用于检测尿液样本中的化学成分或挥发性有机化合物,是为了对不同的尿液成分进行分类,以便能够准确诊断疾病和其他元素。本研究使用来自马来西亚大学(UTM)健康中心的13名患者的尿液样本进行尿液分析。研究结果显示,6名患者出现粘液异常,只有1名患者出现细菌异常,2名患者健康。使用Cyranose 320电子鼻进行的试验表明,尿液中存在挥发性化合物。主成分分析(PCA)用于从32个尿液分析传感器中提取第一和第二主成分。研究表明,利用电子鼻作为糖尿病和细菌感染等疾病的早期检测系统的可能性。
