Fujirebio Expands Its Neuro Testing Portfolio With the Launch of the Fully Automated Lumipulse® G pTau 217 CSF Assay for Research Use Only
28.1.2026 08:07:00 EET | Business Wire | Press release
H.U. Group Holdings Inc. and its wholly-owned subsidiary Fujirebio today announced the availability of the Lumipulse G pTau 217 CSF assay for the fully automated LUMIPULSE® G immunoassay analyzers. This CLEIA (chemiluminescent enzyme immunoassay) assay is available for Research Use Only (RUO) and allows for the quantitative measurement of Tau phosphorylated at threonine 217 (pTau 217) in human cerebrospinal fluid (CSF) within just 35 minutes.
Alzheimer’s disease (AD) is characterized by the accumulation of neurofibrillary tangles in the brain, composed of hyperphosphorylated tau, and amyloid plaques, consisting of distinct β-amyloid peptides. CSF pTau217 has emerged as an early biomarker for neuropathological changes associated with AD.
This new immunoassay further strengthens Fujirebio’s growing portfolio of neurological biomarkers and reinforces the company’s leading position in the advancement of associated research tools and diagnostics.
“By adding pTau 217 CSF to our neuro portfolio, clinical researchers can gain deeper insights into its potential to discriminate AD from non-AD dementias early in the disease process,” said Goki Ishikawa, President and CEO of Fujirebio Holdings, Inc. “pTau 217 CSF complements our established biomarker panel, including pTau 217 Plasma and other CSF biomarkers, by allowing an even earlier detection of proteins associated with AD-related pathology, providing more confidence in biomarker results or answering specific clinical research questions - offering a more detailed picture of the disease on a single platform.”
The availability of the assay on the fully automated random-access LUMIPULSE G analyzers provides researchers access to convenient, accurate, and robust measurement of pTau 217 in CSF, in addition to blood. Already widely available for routine use in neurological disease testing worldwide, these analyzers meet all necessary quality, throughput, and regulatory requirements.

Forrester: Three Years Into GenAI, Enterprises Are Still Chasing Its True Transformative Value2.4.2026 17:00:00 EEST | Press release
According to Forrester’s (Nasdaq: FORR) latest report, Accelerate Your AI Voyage, most enterprises are struggling to turn growing AI adoption and investment into measurable business impact. One of the key factors holding businesses back is low artificial intelligence quotient (AIQ) — Forrester’s measure of AI aptitude — with many employees lacking a clear understanding of how to use AI. Other barriers include an overemphasis on productivity-focused use cases, difficulty measuring impact, and siloed adoption within individual functions. While these challenges can leave firms frozen in doubt or indecision, the wait-and-see approach to AI adoption is no longer viable. To unlock AI’s full potential, organizations need to focus on four key areas: Define the business outcomes and success metrics for what they want AI to achieve; identify specific use cases for AI deployment aligned to those business outcomes; establish a structured runway to plan, test, and strategically time the deployment

The unified company brings together deep expertise in Technology Expense Management (TEM) and IT Financial Management (ITFM) to help organizations better understand, manage, and reduce total technology spend.
