VeriLumenTM 心肌肌钙蛋白I
The VeriLumenTM cTnI Rapid Test is a fluorescence immunochromatographic assay intended for the quantitative measurement of cardiac troponin I (cTnI) concentration in human whole blood, plasma, or serum. Cardiac troponin I is a highly specific biomarker of myocardial injury and is widely used in the clinical assessment of patients with suspected acute myocardial infarction (AMI). The assay provides rapid and sensitive quantitative results to support timely evaluation in laboratory and point-of-care settings.
This test is mainly used as an aid in the clinical assessment and auxiliary diagnosis of myocardial infarction, supporting healthcare professionals in evaluating patients presenting with chest pain and other symptoms suggestive of acute coronary syndromes. Quantitative cTnI measurement may also assist in monitoring cardiac injury progression when interpreted together with clinical findings and other diagnostic information.

| Notes on Handling | Specimens should be collected and handled using standard laboratory procedures. Use fresh samples when possible and avoid hemolyzed, lipemic, or contaminated specimens. |
| Detection Method | Quantitative fluorescence immunochromatography |
| Antibody Format | Monoclonal / sandwich |
| Signal Generation | Fluorescence signal (fluorescent-labeled immunochromatography) |
| Reading Method | Instrument-based |
| Mechanism | The assay is based on a fluorescence immunochromatographic sandwich principle, in which cardiac troponin I (cTnI) present in the sample binds to specific fluorescently labeled anti-cTnI antibodies during capillary migration along the membrane. The resulting antigen–antibody complexes are captured by immobilized antibodies at the test region, and the fluorescence signal is measured and correlated with the cTnI concentration in the specimen. |
