Background: There is increasing interest for the assessment of neurodegenerative biomarkers in blood, which have previously been restricted to cerebrospinal fluid (CSF). For example, methods for measuring total tau in serum and plasma have, until recently, been unavailable. We employed a new technology (Single molecule arrays, Simoa) capable of ultrasensitive protein measurements to measure changes of Abeta1-42 and total tau in different clinical applications, sports-related concussion and Alzheimer’s disease.
