Explanation: Scientists have developed a novel blood test to facilitate detection of Alzheimer’s at an early stage. The test gives people up to 15 years warning before the disease developed. Novel test can pick up tell tale proteins called amyloid beta peptides to characterise the disease as it seeps through the bloodstream. In association with the immune chemical analysis using the infrared sensor. Surface is coated with specific antibodies that extract biomarkers for Alzheimer’s from the blood or cerebrospinal fluid. Infrared sensor analyses shows if there are pathological changes in the biomarkers.
