What's the name of the cotton swab that makes nucleic acid?

The cotton swab used for nucleic acid is not an ordinary cotton swab, and the cotton swab used for sampling is called a "sampling cotton swab".

The raw material of cotton swabs in daily life is absorbent cotton. Sampling cotton swabs look similar to ordinary cotton swabs, but the top is actually flocking cotton swabs. Flocking cotton swabs are used because they are more suitable for sampling and testing. Flocking cotton swabs adopt nylon fiber flocking technology, and the front end is coated with vertically fixed nylon short fibers, so that there is no absorption hole in the whole collection area of collecting cotton swabs.

The samples collected in this way will not be dispersed in the fiber, which is beneficial to faster and more efficient elution. Relevant data show that flocking cotton swabs can elute more than 85% of the sample set; Traditional cotton swabs, especially those made of absorbent cotton, cannot completely collect and elute samples.

Matters needing attention in nucleic acid detection

1. Avoid eating 2 hours before the nucleic acid test to avoid vomiting. Do not smoke, drink or chew gum 30 minutes before sampling. Please bring your ID card and arrive at the test center according to the community notice. The weather is cold, and the queuing time for testing may be longer. Do a good job of personal cold protection and warmth. Keep the distance between people above 1 m, line up in an orderly way, not crowded, and avoid talking.

2. Testers should wear masks correctly and take them off before testing; Wear it immediately after testing, and prepare a spare mask to change at any time after pollution. When collecting an oropharyngeal swab, the tester raises his head back, opens his mouth, makes an "ah" sound, and completely exposes his throat.
