Genesis Sampling Swabs Virus Sample Collection Kit in One-stop Service

2022-04-08
The UK Health Security Agency (UKHSA) reported on 21 April that 34 new cases of unexplained acute hepatitis in children have been detected in the UK since the 74 cases in young children on 8 April, bringing the total number of cases to 108.

As the first step of detection, the sampling quality directly affects the results of a series of subsequent detections, and this step is usually lack of enough attention or even ignored. To ensure the quality of sampling, in addition to the standardization of sampling operations, the first thing we need to do is choosing a sampling swab which is in high quality and suitable material.

Sampling swab material used in COVID-19 PCR testing

The US CDC has mentioned in “Interim Guidelines for Collecting, Handling, and Testing Clinical Specimens from Persons for Coronavirus Disease 2019 (COVID-19)” that “Use only synthetic fiber swabs with plastic or wire shafts. Do not use calcium alginate swabs or swabs with wooden shafts, as they may contain substances that inactivate some viruses and inhibit PCR testing.”

 

Sampling swab materials

1. Medical cotton swab

Medical cotton swab is the most common wood-rod cotton swab. It is cheap and easy to obtain, but it may inhibit the PCR reaction, and the wooden rod is not easy to break, so it is not suitable for virus sampling.

2. Rayon swab

It is a swab with a polyester fiber or rayon tip and a plastic rod. Suitable for the collection of virological specimens, with no breaking point.

3. Nylon swab

It is made of nylon fiber by spray technology and is currently widely used for sampling of respiratory viruses such as COVID-19. Compared with the former two, it has high water absorptionhigh virus release rate and high virus stability.
