The Department of Health and Human Services, specifically the National Institutes of Health, is seeking proposals for the analytical validation of a candidate biomarker for neurological or neuromuscular disorders. This solicitation aims to address the gap in biomarker validation by encouraging rigorous analytical validation of the biomarker detection method for one or two specified contexts of use. The research should optimize and standardize the detection method, as well as test the analytic and pre-analytic variables to evaluate and reduce sources of variability when measuring the biomarker. The project duration is from 2024 to 2026, and multiple application due dates are specified. The funding specifics can be found on the grants.nih.gov website.
