SARS-CoV-2 Antigen Kit (Colloidal Gold)

Practical; Easy to Use; Result in 12 Minutes

Easy to Use ATK
In-vitro diagnostic test for qualitative detection of SARS-CoV-2 antigen

Rapid antigenic self-test on a nasal swab by lay users (self-testing) in a private setting to aid in the diagnosis of an active SARS-CoV-2 infection.

SARS-CoV-2 Antigen Kit (Colloidal Gold)

(For Self-testing)

Intended Use

The SARS-CoV-2 Antigen Kit (Colloidal Gold) is intended to be used manually by lay users (self-testing) in a private setting to aid in the rapid diagnosis of SARS-CoV-2 infections. Children (at least 2 years old) younger than 15 years old should be tested by an adult. Rapid diagnosis of SARS-CoV-2 infection will help health care professionals to treat patients and control the disease more efficiently and effectively.

Test Procedure

  1. Allow the kit to equilibrate to room temperature (15–30℃) before testing. Open the kit and identify kit components and instructions.
  2. Collecting the nasal swab sample.
  3. Remove the Dropper Lid from the Extraction Tube. Place and soak the swab into the tube.
  4. Rotate the swab 5–6 times while squeezing the sides of the tube. Make sure the tube is standing upright and reaches the bottom. Leave it for 1 minute.
  5. Stir to mix the contents well. Remove the swab and immediately discard it into the garbage.
  6. Attach the lid to the tube and tighten. Mix the contents thoroughly (by inverting the tube several times).
  7. Remove the cap on top of the Dropper Lid, add two drops (around 70uL) of the sample into the sample well of the cartridge.
  8. Leave the cartridge at room temperature for 12 minutes.
  9. After the 12-minute incubation, read the results. Do not interpret the results after 15 minutes.

Interpretation of Results

Interpretation of Results


  1. The test is only for the qualitative detection of the SARS-CoV-2 antigen in nasal swab samples.
  2. This test detects both viable (live) and non-viable SARS-CoV-2. Test performance depends on the amount of virus (antigen) in the sample and may or may not correlate with viral culture results performed on the same sample.
  3. A negative test result may occur if the level of antigen in a sample is below the detection limit of the test.
  4. Failure to follow the Test Procedure, Interpretation of Results may adversely affect test performance and/or invalidate the test results.
  5. False-negative results may occur if a sample is improperly collected or handled.
  6. Positive test results do not rule out co-infections with other pathogens.
  7. A negative result does not exclude SARS-CoV-2 infection. Negative results should be treated as presumptive and may need to be confirmed by a molecular assay.
  8. False-negative results are more likely after eight days of symptoms.
