(MENAFN- EIN Presswire) EINPresswire/ -- MLM Medical Labs (MLM), a global central and specialty laboratory serving the biopharmaceutical industry, announced the completed validation of the Lumipulse^® G pTau217/Beta-Amyloid 1-42 Plasma Ratio assay as a Laboratory Developed Test (LDT), enabling its use as a blood-based biomarker for inclusion and exclusion in clinical trials in both the United States and Europe.

While the Lumipulse G pTau217/Beta-Amyloid 1-42 Plasma Ratio assay recently received FDA clearance in the United States, it has not yet been reviewed by the European Union and is therefore classified as Research Use Only. As a health institution, MLM is qualified to develop and validate LDTs that align with IVDR requirements for clinical research.

MLM Medical Labs is the first to validate and perform this specific biomarker ratio in clinical trials under the IVDR/LDT framework. This milestone gives Sponsors access to a validated, regulatory-compliant biomarker tool that supports Alzheimer's disease research and the evaluation of inclusion and exclusion criteria in clinical trials.

“Achieving IVDR validation for the Lumipulse assay represents an important regulatory and scientific milestone for MLM,” said Scott Houlton, CEO, MLM Medical Labs.“This achievement allows us to deliver an FDA-cleared and IVDR-validated diagnostic biomarker assay that supports Alzheimer's disease research and early detection in both U.S. and European patient populations.”

The Lumipulse assay measures the ratio of phosphorylated tau (pTau217) to Beta-Amyloid 1-42 in plasma, offering a minimally invasive approach to identify amyloid pathology - a defining characteristic of Alzheimer's disease. The test's validation demonstrates MLM's continued investment in scientific advancement and regulatory excellence, enabling Sponsors to access data that support early detection and therapeutic development with precision and reproducibility.

As a health institution, MLM is permitted to develop and validate Laboratory Developed Tests (LDTs) to support specialized clinical and translational research. This scientific autonomy, combined with IVDR-aligned processes, ensures high-quality biomarker testing that meets the latest regulatory and scientific standards.

MLM continues to expand its scientific and analytical capabilities to support the growing demand for validated biomarker testing in neurodegenerative disease research - reinforcing its position as a trusted partner in advancing Alzheimer's diagnostics and drug development.
