How the Blood Sample is Analyzed

C₂N Diagnostics uses highly sensitive and specialized laboratory technologies to identify and detect certain amyloid beta (Aß) and tau protein fragments, called peptides, that are circulating in the blood and that are known to be associated with presence of brain amyloid plaques. The main test result is a score, called the Amyloid Probability Score 2 (APS2).

How Results are Reported

A report is sent to your ordering healthcare provider. Your provider interprets the positive or negative test result along with other medical information about you. Your provider then discusses the results with you along with next steps in your care and management.
