cTnI FIA Test

The cardiac Troponin I (cTnI) Fluorescence ImmunoAssay (FIA) Test is a lateral flow chromatographic fluorescence immunoassay for the quantitative detection of cTnI in human plasma or whole blood, using the RaFIA system. This test is intended for in vitro diagnostic use only.

The creatine troponin complex, consisting of cardiac muscle troponin I (cTnI), troponin T (TnT) and troponin C (TnC), can adjust the interaction between actin and myosin. Concentration of cTnI is typically low in healthy human blood. However, when an acute myocardium infarction occurs, cTnI is released into the blood quickly, which leads to a rapid increase of cTnI concentration within hours and can last 6 to 10 days. Therefore, the concentration of cTnI in blood or plasma is regarded as a marker for myocardial infarction.

The cTnI FIA Test was developed to detect cTnI in human plasma or whole blood within 15 minutes, without the use of cumbersome laboratory equipment, and requiring minimally trained laboratory personnel.

  • Quantitative, non-subjective results
  • Increased sensitivity and broader detection range compared to rapid tests

RANGES:

  • Working range: 0.1–50.00 ng/mL

PRECISION: 

  • Intra-lot Precision: Intra-lot precision was determined by testing of cTnI reference materials using 10 test devices from the same lot. CV ≤ 15%.
  • Inter-lot Precision: Inter-lot precision was determined by testing of cTnI reference materials using 30 test devices from 3 consecutive lots randomly (10 test devices from each lot). CV ≤ 15%.

ACCURACY:

  • cTnI control materials with two different concentrations were tested by every lot of test device, and the deviations were within ±15%.

LINEARITY:

  • A serial concentration of cTnI reference materials at 0.1–50.00 ng/mL was tested, and the correlation coefficient (R) is ≥0.9900.
