The most boasted feature of this test is the ease of use. All the steps, from sample collection to test interpretation, can be done at home or work. No lab equipment or extra tools are needed.
The Hotgen COVID self-test is CE-marked and approved for home use by the German Federal Institute for Drugs and Medical Devices (BfArM).
How to perform the Hotgen Self-test?
Step 1 – Preparing the test components
To perform a test, you will need:
- 1 Sampling swab
- 1 Sample extraction buffer tube
- 1 Test cassette
All of these are provided in the Hotgen kit.
Step 2 – Collecting the sample
The Hotgen Rapid COVID-19 self-test sample can be taken from the throat or nose:
- Gently insert the swab into your nostril until you feel some resistance.
- Make sure that you don’t touch the outside skin when going in
- Once you feel resistance, rotate the swab gently for a full turn
- Slowly remove the swab
- Tilt your head slightly upward, and open your mouth to make an “ah” sound
- Insert the swab through your mouth so that it hits the back and tonsils
- Rub the swab at least 3 times against each of your tonsils and on the back of your throat
- Slowly draw out the swab
Step 3 – Preparing the sample
Now that you’ve collected the sample with the swab, you should prepare it for testing. To do this, follow these steps:
- Remove the cap off the buffer tube
- Insert the swab into the tube, and soak the tip below the fluid level
- Rotate the swab and press it at least 3 times
- Keep doing this for at least 15 seconds
- When done, remove the swab slowly while squeezing the tube around it
- Dispose properly of the sampling swab
- Recap the buffer tube
Step 4 – Testing the sample
Now that your sample is treated and ready, you can go ahead and test it for SARS-CoV-2 antigens by following these steps:
- Remove the test cassette from its sealed pouch
- Put the cassette on a flat surface (a table, for example)
- Add 4 drops of the treated sample by squeezing the buffer tube over the cassette (into the “S” pit)
- Wait for 15 minutes before you interpret the result
Step 5 – Interpreting the results
The rapid self-test test can detect the COVID-19 antigen in 15 minutes. If you wait more than 30 minutes, the results will become invalid. The Hotgen test is a visual test, which means that you can know the results directly from the test cassette.
The test cassette has 3 marks: “S” stands for sample, “T” stands for test, and “C” stands for control. Here’s how you can interpret the results:
- Positive: A test is positive if two red lines appear, next to “C” and “T”, regardless of how intense the line is.
- Negative: A test is negative if only one red line appears next to “C”
- Invalid: A test is invalid if no line appears next to “C”, regardless of whether there’s a line next to “T” or not. In this case, the test needs to be repeated.
After finishing the test, dispose of all the components in a hazard bag and wash your hands thoroughly.
How does the test work?
The Hotgen Rapid COVID-19 Self-test is an antigen test that targets the nucleocapsid protein (N-protein) on the SARS-CoV-2. The test uses colloidal gold immunochromatographic technology, with the “T line” containing anti-N-protein antibodies. If the N antigen is present in the sample, it will bind to the antibodies on the “T line” and form a visible red line.
Is the rapid self-test accurate?
Yes. Testing for the Hotgen COVID-19 test accuracy was done in China and the results were published in February 2021. The test was compared against RT-PCR results in 223 patients and was found to have:
- 96.3% Sensitivity
- 99.1% Specificity
- 97.8% Accuracy
Frequently asked questions
Who is the rapid test for? This corona self-test can be used at home, work, or anywhere where a rapid result is needed. This can be anyone who has had recent contact with a positive individual, or someone who has mild suspicious symptoms. The test can also be especially beneficial for businesses that are operating during the pandemic, such as medical clinics, retirement homes, therapists, hotels, schools, universities, etc.
Can the rapid test be done without symptoms? The rapid COVID-19 test can be done even if you don’t have symptoms. Nevertheless, if you’re infected and still have a low concentration of the virus in your body (and hence, no symptoms) then the test results might not be completely accurate. Proper precaution and medical consultation are always recommended.
Why are rapid tests important today? Rapid tests are important since they provide reliable and quick results. They are helping contain the pandemic and break the chain of infectivity hand in hand with other available tests. The more we test, the safer we are.
