COVID-19（SARS-CoV-2）IgG/IgM Antibody Test Kit (Colloidal Gold)

Except COVID-19 test kit, we also provide disposable face mask, KN95, disposable gloves, disposable protective cloting etc.

Intended

use COVID-19（SARS-CoV-2）IgG/IgM Test is used for qualitative detection of novel coronavirus IgG/IgM antibodies in human serum, plasma and whole blood. After infection with the novel coronavirus, the common signs include respiratory symptoms, fever, cough, wheezing and dyspnea, etc. In more severe cases, the infection can lead to pneumonia, severe acute respiratory syndrome, kidney failure and even death. Coronaviruses can be expelled from the body through respiratory secretions, transmitted by oral fluids, sneezing, contact, and by airborne droplets.

Principle

COVID-19（SARS-CoV-2）IgG/IgM Test is the detection principle of colloidal gold marked recombinant novel coronavirus (COVID-19) antigen, while nitrocellulose membrane is coated with rat anti-human IgM, rat anti-human IgG and sheep anti-mouse polyclonal antibodies, when specimens containing IgM antibody with colloidal gold marked a novel coronavirus antigen form compounds, the compounds in rat anti-human IgM antibody was captured, presents the colored lines, if the specimen contains IgG antibody,And colloidal gold marked a novel coronavirus antigen form compounds, the compounds was caught the rat anti-human IgG antibody, presents the colored line, when specimens containing IgG and IgM at the same time, form 2 lines at T1 and T2, extra colloidal gold complexes and sheep anti-rat polyclonal antibody to form a line, as quality control line.When there is no IgG and IgM antibody in the sample, only the quality control line presents the color, which is negative.

Test Procedure

Read the instructions carefully before use and bring tests, buffer and specimens were restored to room temperature. 1. 10μL of serum/plasma/whole blood was absorbed and added to the specimen hole (S). 2. Add 1 drop of sample diluent to the test card specimen hole (S). 3.Wait for the colored line(s) to appear. The result should be read at 10-15 minutes. Do not interpret the result after 30 minutes.

Interpretation of Result

Positive：1. Two or three distinct lines appear. One line should always appear in the control line region (C), and another one or two apparent colored line(s) should appear in the test line region(s) (T1 and T2). 2. If a line appears on the quality control line, a line appears on the test line T1, and no sline appears on the test line T2, it indicates that IgG antibody is present in the specimen and no IgM antibody is present. 3. If a line appears on the quality control line, a line appears on the test line T2, and no sline appears on the test line T1, it indicates that IgM antibody is present in the specimen and no IgG antibody is present.。

Negative: One colored line appears in the control region (C). No Apparent colored lines appear in the test lines regions (T1 and T2).

Invalid: Control line(C) fails to appear. Insufficient specimen volume or incorrect procedural technologies are the most likely reasons for control line failure. Review the procedure and repeat the test with a new test device. If the problem persists, discontinue using the test kit immediately and contact your local distributor.

Note: The red line in the test line (T) can show different shades of color. However, even a very weak line should be judged as a positive result during the specified observation period, regardless of the color of the line.
