Analysis of glucose level detection device performance by chemometrics approached and diffuse reflectance fourier transform near infrared spectroscopy / Noor Nazurah Mohd Yatim

Diabetes mellitus is a chronic disease attributed by body that experiences abnormal insulin production that causes high level of glucose in blood. There are three types of blood glucose monitoring which are invasive, minimal invasive and non-invasive. Current glucose measurement method is an invasiv...

There are three types of blood glucose monitoring which are invasive, minimal invasive and non-invasive. Current glucose measurement method is an invasive type of measurement that require draw out blood sample several times a day with pain and stressful feeling.

The analysis tools to analyse all these data were Principal Component Analysis (PCA) to analysis and classify types of sample and Partial Least Squared (PLS) to predict glucose concentration. The glucose solutions with different pH, glucose in Allura red and human body skin were classified by PCA.

The PLS regression model developed was validated by Root Mean Square Error (RMSE) and Coefficient of Determination (R2 ). The best PLS model was achieved by using Multiplicative Signal Correction (MSC) data preprocessing for the glucose level detection in water which are 125 mg/dl (6.9 mmol/1) RMSE and 0.55 R2 .
