Type B. Virus Protection (Cat. GSP1109-2) Ardent BioMed Disposable Sputum Self-Sampling Kits The collection of sputum for the detection of respiratory tract infections is convenient and reliable. Recent publications confirmed that samples collected from lower respiratory tract have a higher positive detection rate of COVID-19 infection than other methods including throat swabs. Sputum collection can be done by self-sampling, which makes it an extremely attractive way of collecting samples for the large scale of screening tests such as COVID-19 and avoiding false negative detection due to the inappropriate collection procedures. However, sputum usually is very thick and sticky. One of the challenges of sputum sampling is how to effectively preserve pathogens like COVID-19, a single strained RNA virus, and/or pathogen nucleic acid from degradation during sample collection and transportation. Description Type B. Preserve pathogens intact such as COVID-19. The main components include HBSS, HEPES, DTT, and the proprietary cocktails that stabilize the pathogen membranes, inactivate RNase/DNase activities and bacterial and fungal growth. Preserved samples can be stored up to two weeks. Ardent BioMed Guangdong Inc. Add: The 4th floor, Cl building, No.11 Kaiyuan avenue, Guangzhou City, Guangdong Province, China. Tel: + 86 400-8783-223
