Lumipulse^® G pTau 217/β-Amyloid 1-42 Plasma Ratio

The Lumipulse G pTau 217/β-Amyloid 1-42 Plasma Ratio must be calculated using the results obtained from Lumipulse G pTau 217 Plasma and Lumipulse G β-Amyloid 1-42-N Plasma on the same patient sample and same LUMIPULSE G1200 analyzer. Use of another manufacturer’s assays may result in significantly different ratios. pTau 217 and β-amyloid 1-42 values determined on patient samples using other manufacturers’ assays cannot be interchangeably used to calculate the Lumipulse G pTau 217/β-Amyloid 1-42 Plasma Ratio which could lead to wrong diagnostic conclusions.
The Lumipulse G pTau 217 Plasma assay should only be used with the Lumipulse G β-Amyloid 1-42-N Plasma assay to calculate the ratio of pTau 217/β-amyloid 1-42. The Lumipulse G pTau 217 Plasma and the Lumipulse G β-Amyloid 1-42-N Plasma assays are not intended to be used individually.
