How to perform the Hotgen Self-test?

To perform a test, you will need: 

  • 1 Sampling swab

  • 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

Nasal Swab 

  • 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 

Throat 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

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
