“GE and the NFL clearly recognize the pressing need to better understand and accurately diagnose mild traumatic brain injury, and we’re honored to be able to showcase how our Simoa technology is able to do just that,” said Kevin Hrusovsky, CEO and Executive Chairman, Quanterix.

Elevated CSF and blood concentrations of neurofilament light chain (NfL) were found to correlate with an increase in the number of relapses, disability worsening, MRI disease activity, and brain volume loss in MS. 3, –, 9 A highly sensitive single molecule array (SIMOA) immunoassay has recently been developed to measure NfL in blood. 6,10 Method: Serum NFL levels were detected using the Single Molecule Array (Simoa) technology in 30 ALS patients and 20 healthy controls (HCs). Results: There was a significant elevated levels of serum NFL in patients with ALS than in the HCs (P < 0.001). Ready-to-use Simoa NfL kits contain all the reagents necessary to run your assay on the HD-X, HD-1 or SR-X™ platform.

NFL was determined with Single Molecule Array (Simoa™) technology (detection threshold 1.95 pg/mL). “GE and the NFL clearly recognize the pressing need to better understand and accurately diagnose mild traumatic brain injury, and we’re honored to be able to showcase how our Simoa technology is able to do just that,” said Kevin Hrusovsky, CEO and Executive Chairman, Quanterix. The performance of SIMOA ® NfL kit is under evaluation in a multicenter study. 35 Preliminary results showed an excellent performance in terms of intercenter variability. 35 The confirmation of these findings could lead to the worldwide implementation of NfL measurements in clinical chemistry laboratories. Neurofilament light chains (NfL) are unique to neuronal cells, are shed to the cerebrospinal fluid (CSF), and are detectable at low concentrations in peripheral blood.

We compared SimoaTM and EllaTM immunoassays to assess serum neurofilament‐light chain levels in 203 multiple sclerosis patients from the OFSEP HD study.

Increase in NfL values >25% is beyond the analytical variation and is suggestive of a clinically relevant increase in NfL. CSV-NFL ökar vidare vid skov av multipel skleros och normaliseras vid lyckosam behandling.

Suspected neuronal damage in the CNS or PNS SIMOA (single molecule array) Can be tested in serum, EDTA-plasma or CSF. Response The result is reported

NfL has been shown to associate with traumatic brain injury, multiple sclerosis, frontotemporal dementia and other neurodegenerative diseases. The Simoa NF-light™ assay is a digital immunoassay for the quantitative determination of NfL in serum, plasma and CSF. Simoa allows reliable detection of NfL in individual serum samples. Results: As of May 2018, 11 centres have confirmed participation in the multisite analytical validation of the Simoa NF-light assay. All centres have agreed to perform 6 kit runs on individual days according to a … Neurofilament light (NfL) Indication.

2020-07-29 · The ability to not only see but also accurately quantify NfL through an easily administered blood test using the ultra-sensitive Simoa platform was instrumental to the success of this project, and NfL was assayed using Simoa. NfL levels across groups and tests were analyzed. Results: Difference in NfL was found between normal and impaired groups and was related to global cognition, processing speed, executive functions and a list of learning tasks with a significant negative effect for all diagnostic groups.

The single molecule array (Simoa) assay technology is significantly more sensitive compared to conventional detection systems like ELISA or electrochemiluminescence immunoassays. Simoa allows reliable detection of NfL in individual serum samples. NFL was determined with Single Molecule Array (Simoa™) technology (detection threshold 1.95 pg/mL).
