    Sodium Azide COVID-19 Test Kit Lateral Flow Test Kits With Sample Buffer Aluminum Foil

    COVID-19 Test Kit Lateral Flow Test Kits Product


    Intended Use


    The kit was used for qualitative detection of 2019 ncovag and was collected from human nasal swab samples.
    2019-ncov is a new type of ncov. It can cause viral pneumonia. The main clinical symptoms are fever, fatigue and dry cough. Some patients develop nasal congestion, runny nose, sore throat, diarrhea and other symptoms. Severe cases usually develop dyspnea and / or hypoxemia after one week. Severe cases quickly develop into acute respiratory distress syndrome, septic shock, difficult to correct metabolic acidosis and coagulation dysfunction.
    The product was qualitatively tested on 2019 ncovag suspicious nasal swab samples by nasal chromatography. In the acute phase of infection, the antigen is usually detected in nasal swab samples. Positive results indicate the presence of viral antigens, but the clinical relevance of the patient's medical records and other diagnostic information is also needed to determine the infection status. Positive results do not exclude bacterial infection or mixed infection with other viruses.
    This kit is used in the homes of laymen in environments outside the laboratory (such as human homes, offices, sports activities, airports, schools and other specific non-traditional places). The test results of this kit are only for clinical reference. It is suggested to conduct a comprehensive analysis of the condition according to the patient's clinical manifestations and other clinical examinations.

    Principle of Detection


    This kit is based on the principle of double antibody sandwich technology. The 2019ncov monoclonal antibody labeled with the marker is sprayed on the binding pad as an indicator marker. During the test, it was combined with 2019ncov monoclonal antibody labeled 2019ncov - Ag in the sample to form Ag AB complex. The complex moves upward through the capillary effect to form a sandwich complex until it is captured by another pre grouping of 2019 ncov monoclonal antibody on the test line. A red band will appear in the T area of the 2019ncov Ag interpretation window of the sample. If not, it is the result of negation. The control line (c) is used for program control. If the test program runs correctly, it should always be displayed.


    Main Components


    The kit is composed of test card, sample bag and cotton swab.
    Test card: it is composed of aluminum foil packaging, desiccant, test strip and plastic card. The test paper is composed of absorbent paper, nitrocellulose film, sample pad, bonding pad and rubber plate. Nitrocellulose film T-line (test line) is packaged as 2019ncov AB and c-line (QC line), which are wrapped with Goat anti infective antibody and 2019ncovab label binding pad.
    Sample buffer: phosphoric acid, sodium nitride, etc.

    Storage Conditions and Validity



    It is effective for 18 months at 2 ℃ ~ 30 ℃.
    Aluminum foil unpacking is valid for 1 hour.
    Production batch number: see the label for details.
    Validity period: see the label for details.

    Sample Requirements


    (1)Nasal swab collection method: insert the sampling swab into the nostril and insert the swab piece 2.5cm from the edge of the nostril. The cotton swab rotates five times along the nasal mucosa, and then repeat the process with the same cotton swab for the other nostrils (see Figure 1).

    Figure 1 Collection method for nasal swab


    (2) Sample processing: the collected samples are provided as this kit. They are processed as soon as possible (if not immediately, they are kept in sealed containers after drying and sterilization) and kept within 2 hours and 24 hours. Keep it at - 70 ℃ (but avoid repeated thawing and freezing)

    Test Method


    Please read the instructions carefully before testing. Restore all reagents to room temperature before testing. The test must be carried out at room temperature.

    1. sample processing (see Figure 2)

    1. inserts the sample swab into the sample buffer and rotates near the inner wall for about 10 times to dissolve the sample in the solution as much as possible.

    2. squeezes the swab tip along the inner wall of the tube to flow as much liquid as possible into the tube, remove and discard the swab.

    3. Cover with the drops.


    Figure 2 Sample processing


    Figure 3 Detection procedure


    2. Test procedure (see Figure 3)

    1. took out the exam card.

    The 2. adds 2 drops (about 80 μ50) extracts the processed sample into the loading hole of the test card and then activates the timer.

    3. read the results after 15 minutes at room temperature. Invalid results after 20 minutes.


    Interpretation of Test Results


    Description of the test card (Figure 4):
    Invalid ① result: Quality Control Line (C Line) no response line is invalid and should be redetected.
    ② negative result: Quality control line (C) is red ribbon.
    ③ positive results: two red bands, test (T) and mass control (C).


    Figure 4 Interpretation of test results


    Limitation of test method


    1. This product is used for qualitative test and only for invitro diagnosis.
    2. This product is suitable for nasal swab samples. The results of other sample types may be incorrect or invalid.
    3. In order to test, it is necessary to add an appropriate number of samples. Too large or too small sample size may produce inaccurate results.
    4. The test results of this reagent are only for clinical reference and should not be used as the only basis for clinical diagnosis and treatment. The final diagnosis can only be made after a comprehensive evaluation of all clinical and examination results.
