Proprium® H-FABP/cTnI dual test
Product Description
CFDA Approval No.:CE Mark:20142400839


The H-FABP level in blood starts to increase 1-3 hours after an ischemic episode, peak at 6-8 hours and revert to normal within 24-30 hours. The cTnI level in blood starts to elevate in 4-6 hours an ischemic episode, peaks in 24h and sustains for 5-7 days. A combined test for both H-FABP and cTnI is better than either one alone. The cTnI/H-FABP combination has been proposed as the best combination to for a reliable diagnosis of early diagnosis of myocardial infarction/acute coronary syndrome and as a valuable rule-out test for patients presenting at 3 to 6 hours after chest pain onset [1, 2]. The combination test increased the negative predictive values of AMI to 94% at 0 to 3 hours, 98% at 3 to 6 hours, and 99% at 6 to 12 hours [1].

Detection Principle
Colloidal gold immunochromatography technology
Product Performance  

Testing Time: 20 minutes.
Testing principle: A quantitative immunochromatographic test. Anti-human H-FABP/cTnI antibodies conjugated with colloidal gold binding to H-FABP/cTnI when present in the sample.
Testing format: Single use test cartridge with barcode defines lot specific calibration.
Sample Material: Serum/plasma/whole blood.
Performance: A clinical trial showed the concordance rate between the H-FABP/cTnI dual assay and commercial assay for H-FABP and cTnI for positives and negatives are 98.4% and 94.39% for H-FABP and 94.7% and 95.0% for cTnI. No cross-reactivity with cTnC, cTnT, Myoglobin, CK-MB and NT-proBNP.
Measuring Range: cTnI: 0.5-64 ng/ml; H-FABP: 2.5-160ng/ml.
Precision: CV<15%.

 

The product is CFDA approved for clinical use in China and CE marked for IVD use in CE-marking countries (e.g. European countries).
