Process

The Novel Coronavirus (SARS-Cov-2) Antigen Rapid Test Cassette (swab) is an immunochromatographic membrane assay that uses highly sensitive monoclonal antibodies to Novel coroinavirus.

The test device is composed of the following three parts, namely sample pad, reagent pad and reaction membrane. The whole strip is fixed inside a plastic device. The reagent membrane contains the colloidal-gold conjugated with the monoclonal antibodies against Novel coroinavirus; the reaction membrane contains the secondary antibodies for Novel coroinavirus, and the polyclonal antibodies against the mouse globulin, which are pre-immobilized on the membrane.

When the sample is added into the sample window, conjugates dried in the reagent pad are dissolved and migrate along with the sample. If Novel coroinavirus is present in the sample, a complex formed between the anti- Novel coroinavirus conjugate and the virus will be caught by the specific anti- Novel coroinavirus monoclonal coated on the T region.

Whether the sample contains the virus or not, the solution continues to migrate to encounter another reagent (an anti-mouse IgG antibody) that binds the remaining conjugates, thereby producing a red line on the region C.

How Does the Self Test Antigen Rapid Test Kit Work?

Before use, please read the instructions carefully and operate in strict accordance with the instructions:

  1. Bring the pouch to room temperature before use.

  2. Take out the cassette, put it on a horizontal table.

  3. Add 3 drops of the processed sample vertically into the sample well and start the timer.

  4. Observe the result after 15 minutes, the result is valid within 30 minutes, read results after 30 minutes is invalid.

Testing Results

  • Positive: Both the detection line (T line) and the quality control line (C line) appear colors.

  • Negative: The test line (T line) does not appear color, only the quality control line (C line) appears color.

  • Invalid: The quality control line (C line) does not appear color, which means that the test is invalid and the test should be repeated.

Storage and Stability:

The test reagent is stored at 2~30 ℃, and the validity period is tentatively set for 18 months.
