WWHS FIA TT4 Rapid Quantitative Test Kit Application In Fluorescence Immunoassay NIR-1000 Analyser
TT4.pdf
Inspection principle
The T4 Rapid Test is a one-step chromatographic sandwich immunoassay designed for the quantitative measurement of T4. The T4 antigen in the sample was first bound with the conjugated compound of fluorescent labeled T4 monoclonal antibody, then moved and combined with another T4 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-type fluorescence immunoassay.

【Applicable instruments】
NIR-1000 dry fluoroimmunoassay analyser produced by WWHS Biotech. Inc.
【Test procedure】
- Before the test, please read the instructions completely. If the test card and sample are stored in cold storage, they should be balanced at room temperature (15-30)℃ for not less than 30min before use.
- Start NIR-1000 dry fluoroimmunoassay analyser and correctly select the corresponding sample type on the instrument.
- Take out the ID card, make sure that the batch number of the ID card is consistent with that of the test card, and insert the ID card into the ID card port of the instrument.
- Take out the test card from the aluminum foil bag and use it within 15 minutes.
- Place the test card on a clean horizontal table and mark it horizontally.
- Mix 100 µL of patient sample with 200µL of sample diluent. Apply 100 µL of diluted samples to the well of the test card.
- At 15 minutes after addition of samples, insert the test card into NIR-1000 dry fluoroimmunoassay analyser and click the “Instant test” button to read the results.
【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 results
1. This reagent is only used for auxiliary detection. If the test results are abnormal, it should be reviewed in time and judged in combination with clinical symptoms.
2. For samples with AFP concentration lower than 2.5ng/ml and higher than 200ng/ml, the detection results are reported as "< 2.5ng/ml" and "> 200ng /ml", respectively.
Limitations of methods
1. This kit is only used to detect human plasma/whole blood samples
2. Due to the limitations of immunoassay methods of antigen and antibody reaction, the results cannot be used as the only basis for clinical diagnosis, but should be evaluated with all the existing clinical and experimental data.
3. The content of triglyceride in the sample shall not exceed 15mg/ml, the content of hemoglobin shall not exceed 5mg/ml, and the content of bilirubin shall not exceed 0.5mg/ml, and the relative deviation of the test results shall not exceed ±15%.
4. When the concentration of AFP in the sample is less than 20000ng/ml, there is no hook effect.
5. HAMA effect was not produced when the concentration of human anti rat in the sample was less than 50ng/ml.
6. When RF concentration in the sample is less than 2000IU/ml, the relative deviation of the test results is within ±15%.

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.
