SYSTEMS AND METHODS FOR ENRICHMENT OF ANALYTES

摘要

The invention relates to one or more size-based separation modules adapted to increase a concentration of a first analyte in a sample by at least 10,000 fold, wherein said first analyte has an initial concentration in said sample of less than 1 x 10 ^-3 analytes/µL, and an analyzer for analyzing said first analytes in an enriched medium. Methods of using the separation modules for identifying a characteristic associated with a condition in a patient e.g. a fetal abnormality are also provided.
