    2019 NCoV Coronavirus Neutralizing Antibody Rapid Test Immunochromatography Adopts


    Intended Use


    The kit was used to determine the quality of antibodies and antibodies in human serum, plasma, and whole blood.
    Novel crown virus is a new type of corona virus which belongs to the genus Beta. can cause viral pneumonia, the main clinical manifestations are fever, fatigue, dry cough, few patients have a stuffy nose, sore throat, diarrhea. In severe cases, there are respiratory problems and low levels or hypoxia after one week. Severe cases include acute respiratory distress syndrome, septic shock, metabolic acidosis that is difficult to correct, bleeding and coagulation disorders.
    The new type of corona virus has various structural proteins: crest protein, E protein, membrane protein, and nuclear protein. Receptor-associated proteins bind domains responsible for identifying receptors on the cell surface. The results revealed a strong interaction between RBD's 2019 ncv spike protein and the human ACE2 receptor that engulfs host cells and pulmonary viruses.
    After 2019 years of infection or vaccination, it triggers an immune reaction and produces antibodies in the blood. It secretes anti-viral antibodies that are present in the circulating system of the infected human body for months or years and are rapidly and closely linked to pathogens to protect against viruses. These antibodies are known as neutralizing antibodies. Neutralizing antibodies can check whether people have the ability to protect against viral infections.

    Principle of Detection



    used test kit immunochromatography The test card consists of a C, T-line, and R test quality control lines. The entire blood sample control line is measured by capillary action at the s-rbd load end. Binding to proteins marked on the NC film and signal can be detected in T line position. If neutralizing antibodies present in the sample are bound to the s-rbd marker, antigens flowing through the pad neutralizing markers can block the combination of s-rbd and ACE2 and reduce the signal value. negatively correlated with the content of antibodies. When the antibody concentration is high enough, the line is not colored, line R and quality line C will be colored whether the T line is colored or not, quality line C is used for quality control. correct and the sample must be tested again.

    Main Components


    The kit includes a test card and a sample buffer solution.
    The test card consists of a dry aluminum foil bag, a test strip, and a blister card. The test strip consisted of nitrocellulose absorbent paper, sample film, adhesive sheet and rubber sheet. The T line was coated with ACE2 protein, the C line was coated with antibody, the R line was coated with a control antibody, and the 2019 ncv antigen was marked.
    For example, phosphate buffer, sodium oxide, etc.


    Storage Conditions and Validity


    It is stored for months at temperature.
    The shelf life of the aluminum foil bag is one hour after opening the box.
    See the product label for more details.
    Product expiration date, see label for more details.

    Sample Requirements


    1. Water, serum, plasma, or a whole blood sample will be collected.
    2. The sludge and suspended solids in the sample can affect the results obtained from the experiment and should be removed by centrifugal force.
    3. Effects of Heparin, EDTA and Sodium Citrate
    4. The water will be collected by professional medical personnel. It pointed out that the detection of plasma levels should be a special consideration. In an emergency or special situation, a patient's entire blood sample can also be used for a quick examination.
    5. Serum and plasma samples should not be stored at room temperature for more than eight hours, but you should keep them for the next five days. All blood samples must not exceed 48 hours cryogenic freezing.

    Test Method


    Read the instructions carefully before testing. Please recall all chemicals at room temperature before testing and test at room temperature.

    1. Take the test card from the bag packaging and use it within an hour.
    2. The whole serum or plasma or whole blood sample is dripped into the hole of the test card and then dripped to approximately 60μL sample buffer start time.
    3. weight at room temperature and read the result Read the result incorrectly after twenty minutes.

    Interpretation of Test Results



    Figure for judging test card results:
    1. Incorrect result, no reaction on line C, test is invalid and should be repeated.
    2. Negative result, line T shows a red bar greater than or equal to control line C and line R.
    3. Positive results: The T-line or T-line does not have a red band, but its color appears lower than the control line C and the control line.

    Limitation of Test Method



    1.This kit is a qualitative test and is only used for in vitro diagnostic support.
    2. Make sure that the correct number of samples is added for testing. Too large or too small a sample may lead to inaccurate results.
    3. Hemolysis, lipidemia, jaundice, and contaminated specimens may affect test results, so avoid these specimens.
    4. Test results for this reagent are for clinical use only and should not be used as the sole basis for clinical diagnosis and treatment. The final diagnosis of the disease should be made after a comprehensive evaluation of all clinical and laboratory results.
