health π¬ New blood test clears FDA for Alzheimer's diagnosis
C2N Diagnostics' PrecivityAD2 is now the first FDA-cleared blood test for adults aged 40 and older to detect Alzheimer's pathology. This blood-based test is intended for adults 40+ showing cognitive impairment during evaluation. It uses high-resolution mass spectrometry to measure biomarkers like AΞ²42/40 and p-tau217/np-tau217 ratios. The results feed into an Amyloid Probability Score 2 (APS2) ranging from 0 to 100. This could help streamline the complex diagnostic journey for millions facing memory concerns. π¬
