Choice of nasopharyngeal swab:
The main indicators of clinical evaluation of swab performance are the absorption capacity and release capacity of the swab to the target sample at the sampling site. Nylon flocking swabs are made of fine nylon fibers adhered to a plastic rod. Compared with traditional cotton swabs, the adsorption surface is significantly larger, which is conducive to the adhesion and release of pathogenic microorganisms. The ability of nylon flocking swabs and traditional rayon cotton swabs to recover and release known microbial inoculums (spiked samples) confirms that nylon flocking swabs have the ability to release cells, microorganisms, viruses and other microorganisms Significant advantages. Compared with traditional rayon cotton, nylon flocking swabs or foam swabs have a significant advantage in the virus recovery rate in the screening of nasal cavity carrying MRSA virus.
For the choice of virus preservation solution: non-inactivated preservation solution and inactivated preservation solution.
