Implication

Supports Simoa for sensitive serum NfL quantification; leaves open clinical outcome validation in cardiovascular cohorts.

Key Points

To compare the analytical sensitivity and feasibility of ELISA, electrochemiluminescence immunoassay, and Simoa platforms for quantifying neurofilament light chain concentrations in blood samples.
Evaluated neurofilament light chain (NfL) quantification across three analytical platforms: ELISA, electrochemiluminescence (ECL) immunoassay, and Simoa.
Assessed the correlation between serum NfL measurements and established cerebrospinal fluid (CSF) NfL testing.
Simoa exhibited superior analytical sensitivity for quantifying neurofilament light chain in serum compared to both ELISA and ECL immunoassay platforms.
Serum neurofilament light concentrations measured via Simoa correlated with established cerebrospinal fluid neurofilament light test results.

Structured PICO

Does Simoa provide better sensitivity than ELISA or ECL for quantifying neurofilament light chain in blood samples?

Intervention

Simoa technology for quantifying neurofilament light chain (NfL) in serum

Comparator

ELISA and electrochemiluminescence (ECL) immunoassay

Outcome

Assay sensitivity and correlation with CSF NfL testsurrogate

Simoa is a highly sensitive technology for quantifying serum neurofilament light chain, outperforming ELISA and ECL assays, and correlating well with CSF levels.

Limitations

Requires further studies in larger patient cohorts
