Systems and Methods for Developing Diagnostic Tests Based on Biomarker Information from Legacy Clinical Sample Sets
Disclosed are systems and methods for developing diagnostic tests (e.g., detection, screening, monitoring, and prognostic tests) based on biomarker information from legacy clinical sample sets, for which only small sample volumes (e.g., about 0.05 to about 1.0 mL or less per sample) are typically available. For example, biomarkers (e.g., about 10, 50, 100, 150, 200, 300, or more) may be detected in the clinical samples through the use of single molecule detection and each biomarker may be detected in an assay that includes about 1 μL or less of a legacy clinical sample.
