【Product name】
N-terminal prohormone of brain natriuretic peptide (NT-proBNP) Rapid Quantitative Test(Fluorescence immunoassay)
【Package specification】
25 Tests/kit
【Intended use】
This kit is used for quantitative determination of N-terminal prohormone of brain natriuretic peptide (NT-proBNP) in human whole blood and plasma.
【Inspection principle】
The principle of immunofluorescence chromatography was applied to the kit. The NT-proBNP antigen in the sample was first bound with the conjugated compound of fluorescent labeled NT-proBNP monoclonal antibody, then moved and combined with another NT-proBNP monoclonal antibody fixed on the nitrocellulose membrane, and the double antibody sandwich complex was formed at the detection line of the cellulose nitrate membrane. The quantitative detection results were obtained by NIR-1000 dry fluoroimmunoassay analyser.

【Note】
1. This kit is only used for in vitro diagnosis.
2. The test card and sample diluent are disposable and cannot be reused.
3. Please check the integrity and validity of the kit package before use, and then open the package. When it is stored at low temperature, it should be restored to room temperature (15℃~30℃) before opening the package for use. The reagents with damaged inner package and beyond the validity period cannot be used.
4. The requirements of specimen collection and storage should be strictly observed. If the specimen is turbid, it should be centrifuged and discarded before use.
5. The used kits should be treated as potential infectious substances, and all samples, reagents and potential pollutants should be disinfected and treated according to the relevant local regulations.

Interpretation of Test Results
1. The kit can be used for auxiliary test only. If test result is abnormal, retest timely and judge combined with clinical symptoms.
2. For samples whose cTnI concentration is lower than 0.1ng/mL and higher than 40ng/mL, test result is “<0.1ng/mL” and “>40ng/mL” respectively.
Notice
1) The test card can be used only once at room temperature, do not reuse or use test card out of expiry date.
2) Return all reagents and sample into room temperature before use.
3) Be careful when prepare sample, wear glove and mask.
4) The whole blood need add anticoagulants, not frozen; serum sample can store in frozen, avoid repeated freezing and thawing.
5) This product is only for in vitro rapid diagnostic human use, can be quantified, not only qualitative testing.
6) The product test results for reference only, for confirmation, please refer to the relevant national standard methods.
FAQ
1. What is fluorescent immunoassay analyzer?
The Biopanda Fluorescence Immunoassay Analyser is used by small labs for the detection of a range of biomarkers to assist with the diagnosis and monitoring of several medical conditions including cardiovascular disease, inflammation, kidney disease, thyroid conditions, and fertility.
2. Do you have CE certificate for immunoassay analyzer?
WBC analyzer belongs to IVD other/general, no need CE, Ec declaration is enough.
3. How does fluorescence immunoassay work?
Fluorescent Immunoassays are simply a different type of immunoassay. ... A modern fluorescent based immunoassay uses as the detection reagent a fluorescent compound which absorbs light or energy (excitation energy) at a specific wavelength and then emits light
or energy at a different wavelength.
4. What is indirect immunofluorescence assay?
Indirect immunofluorescence, or secondary immunofluorescence, is a technique used in laboratories to detect circulating autoantibodies in patient serum. It is used to diagnose autoimmune blistering diseases.
5. Is immunofluorescence an immunoassay?
Immunofluorescence assay (IFA) is a standard virologic technique to identify the presence of antibodies by their specific ability to react with viral antigens expressed in infected cells; bound antibodies are visualized by incubation with fluorescently labeled antihuman antibody.
