​Treatment of the sample

  • The swab is then placed in an extraction buffer tube.

  • Move the swab back and forth more than 10 times while squeezing the buffer tube. The soaking time of the swab is less than 15 seconds.

  • Remove the swab from the tube and, while doing so, squeeze the tube so that enough liquid is extracted from the swab.

  • Pay attention! Failure to squeeze the tube may cause incorrect test results due to too much buffer in the swab.

  • Finally, press the spout cap firmly onto the tube.
