Is it reliable to extract DNA with oral swab for genetic testing?

A large number of clinical trials of oral cotton swabs abroad show that compared with ordinary sterile cotton swabs, nylon flocking cotton swabs have better effects on the collection and transportation of clinical biological samples, especially for those samples that cannot be sent for inspection in time and have been left for too long.

Sampling swabs can be divided into throat swabs, oral swabs, DNA swabs and cervical swabs according to different uses, which can be used by various laboratory testing centers and hospitals. Compared with the traditional winding swab, the amount of samples collected and released by the sampling flocking swab is three times higher, and it will not cause damage to the cell sample, which well ensures the survival rate of the cell sample, leaving no fatty acids and not affecting the detection results.
