hs-cTnl CLIA Test CE
The high sensitivity Cardiac Troponin I (hs-cTnI) Chemiluminescence ImmunoAssay (CLIA) Test is a chemiluminescence-based immunoassay for the quantitative detection of cTnI in human serum, plasma (lithium heparin, EDTA), or whole blood using the ALTA CLIAlyzer.
Cardiac troponins are sensitive and specific biomarkers used in clinical diagnosis of acute myocardial infarction (AMI).
Troponins appear 4-12 hours after the onset of AMI symptoms and remain abnormally high for 4-10 days in serum. Although conventional troponin assays are valuable diagnostic tools, their sensitivity are lower within the first few hours of symptom onset
The hs-cTnI assays provide higher sensitivity and improved precision than conventional assays. This higher analytical performance of hs-cTnI assays facilitates early diagnosis, risk stratification and effective patient management with early symptoms.
Working range: 0.005 – 50 ng/mL.
Limit of Blank (LOB): ≤ 0.005 ng/mL.
CV less than 8%
CV less than 10%
Linearity between 0.05 and 50 ng/mL.
- Analytical Specificity
The following muscle proteins were tested and found to have an insignificant effect on the measured cTnl.
|Substance||Concentration||% Cross reactivity|
|Troponin C (cardiac)||1000 ng/mL||≤ 0.1%|
|Troponin T (cardiac)||1000 ng/mL||≤ 0.1%|
|Troponin I (skeletal)||1000 ng/mL||≤ 0.1%|
No significant interference was detected up to the concentrations mentioned below:
|Total Protein||≤10 g/dL|
|Rheumatoid Factor||≤1500 IU/mL|
Patient specimens containing human anti-mouse antibodies (HAMA) may give falsely elevated or decreased values. Although HAMA-neutralizing agents are added, extremely high HAMA serum concentrations may occasionally affect the results.
There is no high-dose hook effect at cTnI concentration up to 1000 ng/mL.
