Intended useElecsys β‑Amyloid (1‑42) CSF II is an in vitro diagnostic immunoassay intended for the quantitative determination of the β‑amyloid (1‑42) protein concentration in human cerebrospinal fluid (CSF). The Elecsys β‑Amyloid (1‑42) CSF II assay is intended to be used in adult subjects with cognitive impairment being evaluated for Alzheimer disease (AD) and other causes of cognitive impairment. Result above the cutoff is consistent with a negative amyloid positron emission tomography (PET) scan. Negative β‑amyloid PET scans indicate sparse to no neuritic plaques and are inconsistent with a neuropathological diagnosis of AD at the time of image acquisition; a negative scan result reduces the likelihood that a patient’s cognitive impairment is due to AD. The Elecsys β‑Amyloid (1‑42) CSF II assay is intended to be used in combination with Elecsys Phospho‑Tau (181P) CSF or Elecsys Total‑Tau CSF assay as a ratio in adult subjects with cognitive impairment being evaluated for AD and other causes of cognitive impairment wherein a positive and negative CSF result are concordant with positive and negative amyloid Positron Emission Tomography (PET) scan result, respectively. Elecsys β‑Amyloid (1‑42) CSF II assay is intended to be used alone or in combination with Elecsys Phospho-Tau (181P) CSF or Elecsys Total‑Tau CSF assay as a ratio in adult subjects with mild cognitive impairment (MCI) as an aid to identify subjects who are at lower vs. higher risk of cognitive decline as defined by change in a clinical score within a 2 year period.Limitations of useElecsys β‑Amyloid (1‑42) CSF II assay is an adjunct to other clinical diagnostic evaluations. A positive Elecsys β‑Amyloid (1‑42) CSF II assay result and/or a positive Elecsys Phospho-Tau (181P) CSF or Elecsys Total‑Tau CSF to Elecsys  β‑Amyloid (1‑42) CSF II ratio result does not establish a diagnosis of AD or other cognitive disorder.The safety and effectiveness of the Elecsys β‑Amyloid (1‑42) CSF II assay have not been established for monitoring responses to therapies.
