SARS-CoV-2 Antigen Rapid Test Kit

This product is used for in vitro qualitative detection of SARS-CoV-2 antigen in human oropharyngeal swabs, nasal swabs and nasopharyngeal swabs. It is helpful as an aid in the screening of early mild, asymptomatic, or acute patients for identification of SARS-CoV-2 infection.

Product Features

Easier: No special equipment needed; Easy to use; Intuitive visual interpretation.
Rapid: Results in 10 minutes.
Accurate: Results were validated by PCR and Clinical diagnosis.
Diversity: Works with oropharyngeal swab, nasal swab and nasopharyngeal swab.

How Does the SARS-CoV-2 Antigen Rapid Test Kit Work?

Test Procedure

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 10 minutes, the result is valid within 30 minutes, read results after 30 minutes is invalid.

Testing Results

Test Procedure

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.

Kit Components & Storage

Materials supplied:

1.Test reagent: 1 test/pouch, each test consists of a test cassette and a desiccant. The cassette is composed of a test strip and a test strip shell.

2. Desiccant: 1 piece/pouch, silica gel.

3. Swab: 25 pieces/pack.

4. Sample treatment solution: 20 mL/bottle.

5. Sampling tube: 25 pieces/pack.

Limitations of COVID-19 IgM/IgG Rapid Test Kit

1.This kit is a qualitative test for in vitro auxiliary diagnosis.

2. Due to methodological limitations, the sensitivity of this kit is lower than that of PCR. Therefore, more attention should be paid to the negative results of this experiment, and a comprehensive judgment should be combined with other test results. It is recommended that the suspected results be supplemented with nucleic acid testing or virus isolation and culture in vitro for confirmation.

3. Unreasonable sampling, transportation and handling, or low virus content in the sample will lead to false negative results.

4. The test results of this reagent are for clinical reference only and cannot be used as the only basis for clinical diagnosis. The tester should conduct a comprehensive evaluation based on the patient's clinical manifestations and other laboratory test results.
