Instruction

COVID-19 Antigen Rapid Test Principle

According to the gold immunochromatographic test principle, double antibody sandwich method is used to detect SARS-CoV-2 antigen in the samples. When the antigen is contained in the sample, the antigen binds with the corresponding gold labeled monoclonal antibody 1 and the coated monoclonal antibody 2 at the test line to form a compound and then condenses into a red band, indicating a positive result. When the sample does not contain antigen, complex cannot be formed at the test line, and no red band appears, indicating negative result.

Regardless of whether the SARS-CoV-2 antigen is contained in the sample, the gold labeled antibody will bind with the coated antibody at the C line to form a complex and develop color (C line).

COVID-19 antigen rapid test sample requirement

Nasopharyngeal swab collection method

The operator holds the swab by the right hand and holds the head of the subject fixedly by left hand. Do not overexert to avoid traumatic hemorrhage. When the cusp of the swab touching the paries posterior of the pharyngonasal cavity, letting the swab remain in the place for a few seconds (about 3 seconds) and rotating the swab gently for one cycle,and then remove the swab slowly. Using the same swab, repeat this process for the other nostril to ensure that an adequate sample is collected from both nasal cavities.

Collection method of oropharyngeal swab

The head of the person to be collected is slightly tilted and his mouth is wide open, exposing the pharyngeal tonsils on both sides. Wipe the swab across the root of the tongue. Wipe the pharyngeal tonsils on both sides of the person to be collected back and forth with a little force for at least 3 times, and then wipe up and down the posterior pharyngeal wall for at least 3 times.

Coronavirus Antigen rapid test procedure

Instructions must be read entirely before taking the Covid-19 antigen rapid test. Leave the reagent and sample at room temperature for 30 minutes before use. Return to room temperature. Do not open the inner packing until it is ready. Use it as soon as possible after opening the inner packing.

Sample Treatment:

Add 500μl (~20 drops) of sample extract to the 0.5 mark of the sampling tube, dip the swab after collecting the sample into the sample extract, make the sample extract fully permeate the swab, rotate and squeeze the swab 10 times, then pull out the swab, and take the stranded liquid as the sample to be tested.

Coronavirus Ag Rapid Test Sample

1.

Open the tear hole of the aluminum foil bag, take out the test card and lay it flat.

2.

Apply 2-3 drops of the treated sample extract (60μl-80μl) vertically into the sample well of the test cassette.

3.

The results are observed after 15 minutes and showed no clinical significance after 20 minutes.

Performance characteristics of the COVID-19 Antigen rapid test

Positive

Two distinct red lines appear. One line should be in the control region (C) and the other line should be in the test region (T).

Negative

One red line appears in the control region (C). No red line appears in the test region (T). The negative result does not indicate the absence of analytes in the sample, it only indicates the level of tested analytes in the sample is less than cut-off level.

Invalid

No colored lines appear or control line fails to appear, indicating that the operator error or reagent failure. Verify the test procedure and repeat the test with a new testing device.

Attentions

5

The reagent is a disposable diagnostic reagent in vitro, which is only used for the detection of human nasopharyngeal swab, or oropharyngeal swab. The operation should be carried out strictly according to the instructions. Do not use expired and damaged products.

5

The strength of the quality control line does not mean the quality of the reagent, as long as its color is clear and visible, that means the reagent is effective.

5

The coronavirus antigen rapid test kit should be sealed and kept away from moisture. Reagents or samples stored at low temperature should be balanced to room temperature before they can be used.

5

Reagents should be used as soon as possible after removal from aluminum foil bags, so as to avoid exposure to air for too long and affecting test results due to dampness.

5

Do not use samples that have been placed for too long or contaminated.

5

Please operate in accordance with the laboratory testing procedures for infectious diseases. Waste after use should be treated in accordance with infectious substances and should not be discarded at will.

5

Incorrect operation may affect the accuracy of the results, such as insufficient sample mixing, insufficient amount, inaccurate detection time, etc.

5

Components in different batch should not be mixed.

5

There should be appropriate biosafety assurance procedures for those substances containing and suspected sources of infection.

5

The following are relevant considerations:

  1. Handle samples and reagents with gloves;
  2. Do not suck samples with your mouth;
  3. Do not smoke, eat, drink, cosmetic or handle contact lenses while handling these items;
  4. Disinfect the spilled sample or reagent with disinfectant;
  5. Disinfect and treat all samples, reagents and potential pollutants in accordance with relevant local regulations;
  6. Each component of the reagent remains stable until the expiry date under proper handling and storage conditions. Do not use the expired reagent kit.
