This kit is for in vitro diagnostic use. ## Device Story IMUBIND Plasma PAI-1 ELISA is an enzyme-linked immunosorbent assay (ELISA) for quantifying PAI-1 antigen in human plasma. The device utilizes plate wells coated with anti-PAI-1 antibody to capture PAI-1 from patient samples. Following incubation and washing, bound antigen is detected via standard ELISA reagents. The assay is performed in a clinical laboratory setting by trained personnel. Results are obtained via absorbance measurements, which are used by clinicians to assess PAI-1 levels; elevated levels are clinically associated with deep vein thrombosis and myocardial infarction, aiding in the evaluation of thrombotic risk. ## Clinical Evidence Bench testing only. Method comparison studies against the predicate device demonstrated a positive correlation. Precision studies evaluated intra-assay and inter-assay variability across two lots, with intra-assay CVs ranging from 4.1% to 5.7% and inter-assay CVs ranging from 2.1% to 5.1%. ## Technological Characteristics Enzyme-linked immunosorbent assay (ELISA) format. Uses antibody-coated microtiter plates for antigen capture. Quantitative measurement based on absorbance. In vitro diagnostic reagent kit. ## Predicate Devices - BIOPOOL TintElize® PAI-1 ([K960438](/device/K960438.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
