Even if the public has mastered the required technical requirements, the relevant procedures can cause uncomfortable reactions such as coughing or sneezing, and the droplets produced during the period can spread diseases.

Those with inexperience may break the throat swab during the collection period, causing accidents of swallowing foreign objects. Some people with chronic diseases, such as those with blood clotting disorders, long-term use of thin blood pills or anti-platelet drugs, may cause trauma and bleeding problems if they use excessive force when taking a throat swab.
The Association believes that local and overseas scientific studies have confirmed that compared with other respiratory samples, deep throat saliva is not inferior in virus detection capabilities, and the laboratories of various hospitals in Hong Kong have matured the technology.
