    摘要： A biosensor screening system and method is disclosed that assesses functional integrity/capacity of biosensor samples and identifies the biosensor samples that may potentially cause failure such as shutdown of biosensor during normal use. Features of the disclosed biosensor screening system and method may include connecting to a biosensor to a biosensor screening test apparatus, conducting a biosensor screening test using the biosensor screening apparatus on the biosensor connected to the biosensor screening test apparatus, collecting data attributes from the biosensor after completing the biosensor test, scaling the collected data attributes, and obtaining a screening test score.
