Pathological phosphorylation (yellow) of Tau proteins (red-orange).Getty Images/iStockphoto Detecting Alzheimer’s disease remains a challenge because its early symptoms can be subtle, but it’s becoming more critical as new treatments emerge. Often by the time symptoms of memory loss and cognitive decline appear, the degenerative brain condition is more difficult to treat. AlzPath developed the first commercial blood test for ptau217 in the blood, one of the early signs of neurodegeneration, that doctors can now order through specific labs to help identify patients sooner. It’s one of several tools doctors can utilize to improve diagnosis of patients, and in 2024, the company licensed its antibody to Roche to include in Roche’s diagnostic antibody-based testing platform. Roche then partnered with Eli Lilly to receive a Breakthrough Device designation by the FDA in April, which accelerates the development and review process for the blood test. **Correction, Oct. 30** _The original version of this story misstated what AlzPath licensed to Roche, and the month of its Breakthrough Device designation. It licensed the antibody, not a test, and the designation was received in April, not June._ These are independent reviews of the products mentioned, but TIME receives a commission when purchases are made through affiliate links at no additional cost to the purchaser. ```json [{"@context":"https://schema.org","@type":"Article","@id":"https://time.com/collections/best-inventions-2024/7094900/alzpath-ptau217-antibody/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/collections/best-inventions-2024/7094900/alzpath-ptau217-antibody/"},"headline":"ALZpath pTau217 Antibody: the 200 Best Inventions of 2024","datePublished":"2024-10-30T11:17:11.000Z","dateModified":"2026-04-13T11:54:34.114Z","description":"Find out why ALZpath pTau217 Antibody is one of the best inventions of 2024","url":"https://time.com/collections/best-inventions-2024/7094900/alzpath-ptau217-antibody/","keywords":["Tech","E-Commerce","list","franchise","Magazine","best inventions"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blte9fccf60362870d1/698a8a38db2987286f270ca4/ALZpath-pTau217-Antibody.jpeg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Alice Park","jobTitle":"Senior Correspondent","url":"https://time.com/author/alice-park/"}],"creator":"Alice Park","articleSection":"Business","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blte9fccf60362870d1/698a8a38db2987286f270ca4/ALZpath-pTau217-Antibody.jpeg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/business/","name":"Business"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/time-section-tech/","name":"Tech"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/collections/best-inventions-2024/7094900/alzpath-ptau217-antibody/","name":"ALZpath pTau217 Antibody: the 200 Best Inventions of 2024"}}]}] ```
