How to use a sterile swab

Sterile swabs, the full name of single-use sterile sampling swabs, are used in bacteriological sample processing, COVID-19, nasal swab sampling, throat swab sampling, oral swab sampling, virological cell culture, DFA testing, Rapid and direct testing, enzyme immunoassay testing, polymerase chain reaction and molecular diagnostic-based testing, as well as forensic identification are ideal. It can also be used for throat sampling of respiratory viruses such as influenza, swine influenza, avian influenza, hand, foot and mouth.

The sterile flocking swab is suitable for humans and animals. It has advantages over other DNA test samples in design. Its unique test sample matrix and quick release interface are more conducive to efficient cell collection and maximize DNA yield. The test piece has been sterilized with ethylene oxide and passed the test for human DNA contamination.

Sterile swabs are suitable for skin surface sampling, such as DNA collection, oral cells, surface, microorganisms, bacterial and virus detection sampling, etc. The advantage is that it is easier to use than traditional swabs. The collection and release volume is large, and it can be broken. Traditional swabs The lab staff also need to use scissors to cut it, which is too troublesome and too time-consuming. Our new flocking one-time sampling swab greatly reduces the time cost.

Instructions

Pharyngeal swab sampling

1. Open the swab package first, take out the swab carefully, and be careful not to touch anything before sampling to avoid contamination.

2. The sampler can first use the tongue depressor to remind the patient to make an “ah~” sound.

3. Raise the patient’s palate to expose the posterior pharyngeal wall. Pass the swab across the base of the tongue to the back of the pharynx (lesions) and quickly wipe the palatal arch, pharynx and tonsil secretions on both sides (15-30 seconds).

4. Put the sampled swab into the virus sampling tube, and break the swab rod at the mouth of the tube cover to completely place it in the tube.

5. Tighten the cap of the tube, make a mark, and put it in a biosafety bag and seal it.

6. Submit the specimens for inspection in time.

Nasal swab sampling

1. Open the swab package first, take out the swab carefully, and be careful not to touch anything before sampling to avoid contamination.

2. Ask the patient to keep his head still and remove the secretions on the surface of the anterior nasal cavity (it is best to let the patient blow his nose first).

3. The sampler can stand on the side of the patient, reducing the chance of infection caused by coughing and sneezing, and at the same time alleviating the pressure of the sampler.

4. Measure the distance from the nostril to the root of the ear with a swab and use the hand as a mark.

5. Slowly insert the nasal swab into the nostril (toward the earlobe), with a feeling of touching the wall, let the swab stay in the nose for 15-30 seconds, and then gently rotate it 3 to 5 times.

6. Take out the swab slowly and put it vertically into the virus sampling tube.

7. At the breaking point, break off the swab, discard the tail, and place the swab completely in the tube.

8. Tighten the cap of the tube, make a mark, and put it in a biosafety bag and seal it.

9. Submit the specimens for inspection in time.
