Intended use

Cardiac Troponin I (cTnI) Kit (Immunofluorescence) is mainly for the in vitro quantitative determination of cardiac Troponin I (cTnI) content in human serum. Cardiac Troponin I (cTnI) as one of the units of cardiac troponin (cTn), only exists in the atrial and ventricularmyocytes, when myocardial cell membrane is complete, cTnI cannot penetrate the cell membrane into the blood circulation; when myocardial cells become necrosis due to ischemia or hypoxia, cTnI can enter the cytoplasm through damaged cell membrane, then enter the bloodstream, so cTnI can be used as an acute diagnostic index for acute myocardial infarction (AMI). Clinical circumstance suggests that some non-AMI diseases cause release of cTnI, such as unstable angina pectoris, congestive heart failure and ischemic injury caused by coronary artery bypass.


Test principle

The assay is a double-antibody sandwich immunoassay for quantitative determination of cTnI concentration based on immunofluorescence technology. Add the sample to the sample well of the cartridge. Through chromatography, the sample reacts with the fluorescent latex particles coated with cTnI monoclonal antibodyⅠand cTnI monoclonal antibodyⅡ on the conjugate pad. The complex spreads ahead along the nitrocellulose membrane captured by cTnI monoclonal antibody Ⅲ on the test line. The more cTnI the sample contains, the more complexes the test line accumulates. The intensity of fluorescent antibody signal reflects the amount of captured cTnI. The immunofluorescence quantitative analyzer produced by our company can detect the concentration of cTnI in the sample.

Warnings and precautions

For in vitro diagnostic use.

The package insert must be carefully . Reliability of the test results cannot be guaranteed if there are any deviations from the package insert.


Safety precautions

CAUTION: This product requires the handling of human samples. It is recommended that all human sourced materials are considered potentially infectious and be handled in accordance with the OSHA Standard on Bloodborne Pathogens. Biosafety Level 211 or other appropriate biosafety practices should be used for materials that contain or are suspected of containing infectious agents.

Appropriate protective measures should be taken in the collection, processing, storage, mixing of the sample and testing process; once the sample and the reagent contact skin, wash with plenty of water; if skin irritation or rash occurs, get medical advice/attention.

Samples, used cartridge and disposable tips may be potentially infectious. Proper handling and disposal methods should be established by the laboratory in accordance with local regulations.


Handling precautions

Do not use the kit beyond the expiration date. The production date and expiration date are on the label.

Different batches of sample diluent, calibration cards and cartridges cannot be mixed.

The cartridge is disposable and cannot be reused.

Please do not use obviously damaged kit or cartridge.

Do not insert the cartridge wetted by other liquids into the analyzer, in order not to damage and pollute the instrument.

Please avoid high temperature in the lab.

The calibration card and immunofluorescence quantitative analyzer should keep away from vibratile and electromagnetic environment when used. Slight vibration of the instrument is normal. Do not pull out the cartridge during testing.

To avoid contamination, wear clean gloves when operating with kits and samples.

For a detailed discussion of handling precautions during system operation, refer to the NORMAN service information.


Specimen collection and preparation

The serum must be collected by standard tubes or pro-coagulation tube filled inside with separation gel. The sample is advised to be tested immediately. If not, store the sample at 2-8℃; If testing is delayed more than 24 hours, then store the sample at -20℃ or below.

Heat inactivated and hemolysis samples should be abandoned. If there is precipitation in the serum, centrifugation must be done before testing.

The samples must reach room temperature(10-30℃) before the test. The cryopreserved sample can only be used after complete melting, rewarming and mixing. Avoid repeating freezing and thawing samples.


Procedure

Preparation

Installation of the immunofluorescence quantitative analyzerNRM-FI-1000and reagent strip incubator

Please read the operator’s manual of the immunofluorescence quantitative analyzer(NRM-FI-1000)and reagent strip incubator carefully before use.


Calibration Card installation

Each box contains a lot-specific Calibration Card to correct for lot-to-lot deviation.

Turn on the power switch, according to the system self-test prompt, waiting for the instrument to display the main interface.

Press “Assay Management”.

Insert the Calibration Card into the card slot following the direction of the arrow, then press “Read". Confirm the lot number of the Calibration Card with the reagent relevant information, then press "Ok".

Press “Return” to the main interface.


Cartridge

Cartridge needs to reach room temperature before opened.


Test procedure

Remove the cartridge (after reaching room temperature), draw in 90μL of the sample to the well and incubate it for 15 minutes in the reagent strip incubator.

After incubation insert the cartridge into the immunofluorescence quantitative analyzer(NRM-FI-1000) using the cartridge arrows as a guide, and click start, then the instrument will scan the cartridge automatically.
