Nucleic acid swabs do not have any drops on them. The term “nucleic acid swab” refers to a sampling swab used during nucleic acid testing, usually in the collection of human nasal, pharyngeal, laryngeal and anal secretions. This special sampling swab is actually composed of a nylon staple fiber fluff head and a medical grade ABS plastic rod, which does not contain any medicine or impurities. And it also has the following two characteristics: 1. The swab is flocked with spray and electrostatic charge to make millions of nylon microfibers vertically and uniformly attached to the end of the shank. 2.The flocked swabs keep microbial samples on the surface of the fibers, quickly eluting >95% of the original sample, easily increasing the sensitivity of the test. “Nucleic acid swabs” is a unique material, which does not contain any chemicals or harmful ingredients, on the contrary, with the help of a professional test will help us to improve the accuracy of the nucleic acid results.
