Blood Test In Development To Diagnose Pre-Clinical Alzheimer’s Disease

A new blood test being developed was able to identify biomarkers of Alzheimer’s disease before the start of clinical symptoms. The test was 84% accurate in a recent small clinical trial. The researchers are now using the test in a larger trial with 800 people.

The blood test is based on an immuno-chemical analysis using an infrared sensor. The surface of the sensor is coated with highly specific antibodies which extract biomarkers for Alzheimer’s from the blood or the cerebrospinal fluid, taken from the lower part of the back. The infrared sensor analyzes if the biomarkers show . . .
