What is a Longsee Rapid Detection Kit for COVID-19?

The Longsee SARS-CoV-2 test is a rapid test method for the rapid detection of infection with Covid-19. It is based on immunochromatography technology, requires only a few test steps and provides a result within 15 minutes.

Can the Longsee rapid test detect mutations?

Yes, mutations such as the Omikron mutation can be detected with the COVID-19 antigen rapid test from Longsee. This is also confirmed by the Common RAT List of the HSC (List of COVID-19 Antigen Rapid Tests of the European Commission).

Is the Longsee rapid test safe?

The Longsee COVID-19 Antigen Rapid Test has been evaluated by the PEI and has an overall sensitivity of 100%. The sensitivity of the test is 95.51% and the specificity is 99.72%. As the test is on the "Common List" (list of the European Commission), it can be assumed that it is classified as safe.

How does the Longsee Rapid Detection Kit for COVID-19 work?

By nasal, nasopharyngeal or oropharyngeal sampling.

How long does the test result of the Longsee Rapid Detection Kit for COVID-19 take?

15 Minutes.

How is the Longsee Rapid Detection Kit for COVID-19 packaged?

There are 25 tests per pack/box, in a whole box 700 pieces.

How long can professional Longsee Rapid Detection Kit for COVID-19 be stored?

Can be stored at room temperature or from 4 to 35 degrees for up to 12 months.

Does the Longsee test recognise the Omikron variant?

Yes, the tests have been checked by the Paul Ehrlich Institute. The Omikron variant is fully proven.

How did the tests perform in the Paul Ehrlich Institute's control list?

The tests are on the list that meet the sensitivity criterion. You can read the exact details here.

Instructions for use

[INTENDED USE]

The rapid detection kit in this package is designed for the qualitative determination of SARS-CoV-2 nucleocapsid antigen in nasal or throat swab specimens from individuals suspected to have COVID-19 infection. The kit is intended for rapid diagnosis of SARS-CoV2 infections.

For professional use only. For in vitro diagnostic use only.

[SUMMARY]

The novel coronaviruses belong to the genus β. COVID-19 is an acute respiratory infectious disease. People are generally susceptible. Patients infected with the novel coronavirus are the main source of infection; asymptomatic infected persons can also be a source of infection. Based on the current epidemiological investigation, the incubation period is 1 to 14 days, mostly 3 to 7 days. The main manifestations are fever, fatigue, and dry cough. In some cases, nasal congestion, runny nose, sore throat, myalgia, and diarrhea can also be observed.

[PRINCIPLE OF THE TEST]

This kit uses immuno-chromatography technology to detect the presence or absence of 2019-nCoV nucleocapsid proteins in swab specimens from patients with signs and symptoms of infection, where there is suspicion of 2019-nCoV by the double antibody sandwich method. When the concentration of 2019-nCoV antigens in specimens is higher or equal to the minimum detection limit, these antigens react separately with corresponding antibodies to form complexes, and the 2019-nCoV antibodies are coated in the detection area (T). These antigens are captured and a red reaction line is formed. The result is considered positive. Otherwise, the result formed in T without a red line is considered negative. Under normal test conditions, the quality control area (C) should be colored to indicate that the test is valid.;

[COMPONENTS]

[RESULT EVALUATION]

To read the test results, you just need to look at the observation window.

1. Positive: If two color bands are visible at the position of the quality control line (C-line) and the test line (T-line) in the result window, the test result is positive. The test result indicates the presence of 2019-nCoV antigens in the sample.

2. Negative: If a color band appears at the position of the quality control line (C-line) and no color band appears at the detection line (T-line) in the observation window, the test result is negative. The test result indicates that the sample is negative for 2019-nCoV antigens or the concentration is below the detection limit of the set.

3. Invalid: If no band appears at the position of the quality control line (C-line) and the test line (T-line) in the observation window, the test result is INVALID. The sample should be re-taken and the test repeated.

[LIMITATIONS]

1. The Longsee Rapid Detection Kit is intended for professional use only and for in vitro diagnostics.

2. This kit is designed to detect the presence of SARS-CoV-2 nucleocapsid antigen in nasal or throat swab specimens from individuals with suspected COVID-19 infection. It is not intended to accurately determine the content of antigens in samples.

3. The accuracy of the results can be affected by improper sample collection and storage.

4. Test results should not be used as the sole basis for clinical diagnosis and treatment. A comprehensive consideration of laboratory examination and treatment response should be taken into account.

5. Negative results must be combined with other test results to make a comprehensive assessment. It is recommended to use nucleic acid tests or methods for virus culture identification for verification and confirmation.

6. False-negative results can be caused by improper sample collection, transport, and processing, as well as low virus titers in the sample. Viral gene mutations can also cause changes in antigenic determinants and result in false-negative results.
