Squeeze the swap head by hand through the outer wall of the sampling tube at least 5 times to ensure that the sample is adequately eluted in the sampling tube.
- 2 Squeeze the liquid from the swab head by hand across the outer wall of the sampling tube, and discard the swabs. After the sampling tube is covered, drop the liquid vertically into the sample hole of the detection card.
- According to the reagent instructions, wait for a certain period of time to interpret the results.
