Heart and brain fatty acid binding proteins (H-FABP, B-FABP) are markers for TSEs, especially CJD. The invention provides a diagnostic assay for either of these markers, preferably by enzyme immunoassay using a specific antibody thereto. Since H-FABP is also a marker for acute myocardial infarction (AMI), to distinguish CJD from AMI requires an assay specific to AMI, e.g. using troponin-1 or CK-MB as a marker, also to be carried out.

The invention discloses a detection method in the technical field of biological engineering, in particular a method for diagnosing cardiac troponin I (cTn I) in a semi-quantitative mode by employing double-indicatrix immunochromatography. Acute myocardial infarction (AMI) is a serious disease in a coronary heart disease, is a common emergency among middle-aged and elderly people, and is high in death rate. According to statistics, one third to a half of patients die before being sent to a hospital. In the next 20 years, the AMI is a primary cause for death of the patients around the world. The cTn I is a reliable index which is currently acknowledged and has the highest specificity and the longest duration for myocardial infarction diagnosis. At present, cTn I detection methods which are commonly used in clinic comprise an enzyme-linked immunosorbent assay method and a radioimmunoassay method, which are time-saving, labor-saving, difficult to popularize and high in cost. An immune colloidal gold technology is quickly developed in recent years and can be widely applied to detection of communicable diseases, early pregnancy and cancers. By employing colloidal gold immunochromatography, a quick detection method for the cTn I is established. By adoption of the method, a cTn I gray area of 1 to 5 ng / ml can be subjected to semi-quantitative detection.
