Do you know that COVID-19 sampling swab ≠ cotton swab? On the 3rd, Sichuan Provincial Drug Administration issued a popular science video to get to know.
Question 1: Is the cotton swab used for COVID-19 detection and sampling?
Answer: It is not a cotton swab, but a sampling swab.
Question 2: What is the sampling swab? How is it different from cotton swabs?
Answer: Sampling swab is a tool used to collect samples of viruses, bacteria, etc., and generally consists of swab head and swab rod.
The difference between the two is mainly reflected in the composition and use:
The cotton swab head of the cotton swab is made of medical absorbent cotton. The cotton swab stick is generally natural birch or bamboo swab, which is often used to clean wounds and apply medicine.
The swab head of the sampling swab is generally made of polyester (also known as polyester), polyamide (also known as nylon) and other chemical synthetic fibers by flocking process, and the swab rod is generally medical grade ABS plastic with breakpoint, often used for virus or bacterial sample sampling.
Question 3: Why should we use a sampling swab for COVID-19 detection?
Answer: Although sampling swabs are as non-toxic and harmless as cotton swabs; However, compared with cotton swabs, sampling swabs have the advantages of non adsorption of samples, easy elution, easy breaking, simple operation, and no impact on the detection results. Therefore, sampling swabs are used for COVID-19 detection instead of cotton swabs.
