The cotton swab for nucleic acid detection is non-medicated, and its top is similar to that of ordinary cotton swab. The cotton swab used for nucleic acid detection is called sampling cotton swab, and there is no reagent. It is similar to a common cotton swab, except that the top of it is a flocking cotton swab, and the top of the common cotton swab is absorbent cotton.
The biggest difference between them is that cotton swabs in daily life are absorbent cotton, while sampling cotton swabs look similar to ordinary cotton swabs, but they are actually flocking cotton swabs. So be sure to do nucleic acid on time.
