Description

technical field

[0001] The invention belongs to the field of medical detection, and mainly relates to a sample pad sealant, a preparation method thereof and an immunochromatographic test strip or a test paper card using the sealant. Background technique

[0002] Cardiac troponin I (cTnI) has been used as an important indicator for judging myocardial cell damage in acute myocardial infarction (AMI), myocarditis and other diseases, and is also recognized as assisting in acute coronary syndrome (acute coronary syndromes, ACS) risk stratification Therefore, it is very important to ensure the accuracy, specificity and stability of cTnI detection results in clinical application.

[0003] One of the commonly used cTnI detection methods is immunochromatography. Immunochromatography (immunochromatography) technology is a fast, simple, sensitive, intuitive, low-cost detection method that can truly realize on-site detection. First fixed on a certain zone of the polymer membrane, when ...
