About this trial
This study compares p-tau217 concentrations in blood collected via the Tasso device versus standard venipuncture in subjects with and without Alzheimer's disease, including a subset with confirmed amyloid pathology.
Eligibility criteria
This trial accepts healthy volunteersQualifiers
AD Amyloid PET/CSF confirmed, healthy control, or amyloid-negative non-AD cognitive impairment Age 40-90 Able to complete Tasso and venipuncture collection Caregiver consent/assistance available if needed
Disqualifiers
Uncontrolled systemic conditions Recent surgery/hospitalization (3 months) Other dementia drug trial (2 months) Pregnancy Prior Donanemab or Lecanemab use
Trial population
Adults aged 40-90 recruited through clinical records review, advertising, and community outreach, including AD patients, cognitively healthy controls, and non-AD cognitively impaired individuals with confirmed amyloid-negative status. A subset has amyloid pathology confirmed via PET or CSF.
