Instructions for Use
For professional use
COVID 19 Antigen Test Kit (Colloidal Gold Method)
Test cassette (single test packaging):
1 tests/box; 5 tests/box;10 tests/box; 15 tests/box.
Nasal sampling |
nasopharyngeal sampling |
Oropharyngeal sampling |
|
|
Positive test results: Two purplish red C lines and T lines appear simultaneously in the test area. The results were positive. This indicates that there is COVID 19 in the sample.
Negative test results: The control line(C) is the only visible line in the test area. No COVID 19 antigen was detected. The results do not rule out infection. If symptoms persist, new samples should be taken from patients within 3-5 days and retested.
Invalid test results: If the control line (C) does not appear in the test area, the test result is invalid regardless of whether there are other visible lines in the test area. Retest with a new reagent cassette.
1. Inspection of reference materials of the company:
1.1 positive coincidence rate: COVID 19 antigen reference material P1 ~ P8 should be tested positive, with a coincidence rate of 8/8.
1.2 negative coincidence rate: COVID 19 reference material N1 ~ N20 was used for detection. All of them should be negative, with a coincidence rate of 20/20.
1.3 Detection limit: the COVID 19 reference material S1~S6 was used for detection. ,S1 to S4 should be positive, S5 and S6 do not require.
1.4 reproducibility: COVID 19 antigen reference materials R1 and R2 were used for 10 tests. Results should be positive and the chromaticity was uniform.
2. HOOK effect: COVID 19 antigen positive reference material with the highest concentration was detected in the kit without HOOK effect.
3. there was no cross reaction and interference with the potential cross reacting microorganisms listed below.

1. This product is only used for preliminary screening of in vitro diagnosis. Please do not use it as a confirmation reagent. The positive results must be confirmed in combination of clinical symptoms and other tests.
2. Due to methodological or antigen specificity, testing the same sample with reagents from different manufacturers may result in different test
results. Therefore, the results obtained by testing with different reagents should not be directly compared with each other to avoid incorrect medical interpretation. It is recommended that the laboratory indicate the characteristics of the reagents used in the test report issued to the clinician.
3.Reagents should be kept sealed and kept away from moisture. The reagents and the samples stored at low temperature should be equilibrated to room temperature before use.
4.Please follow the general guidelines for biosecurity in microbiology and biomedical laboratories.
5.The wastes including the used reagents and all samples are potentially infected, please dispose of them as infectious medical wastes.
