The Viral Transport System is designed for the collection, transportation and short-term storage of clinical specimens containing total DNA/RNA such as SARS-CoV-2, chlamydia, mycoplasma, ureaplasma from saliva, blood, serum, stool or other bodily fluids. The transport medium lyses the organism and inactivates the cells, bacteria, and/or virus. The lysed samples can be stored at room temperature for up to one week and used in subsequent procedures such as DNA/RNA extraction, PCR or sequencing. This system contains individually wrapped, sterile flocked nylon swabs optimizing specimen collection and elution into the transport medium.

1. Take the swab out of the package, and swab deep into the oral, nasal, or other cavities for sampling. The specific sampling methods are below:       1.1. Nasal swab: Gently insert the swab into the nasal condyle of the nasal passage. Leave in place for several seconds, and                 slowly remove while rotating. Swab other nostril with separate swabs if necessary.       1.2. Pharyngeal swab: Swab the bilateral pharyngeal tonsils and posterior pharyngeal wall.  2. Twist open the vial and quickly immerse the swab head into the transport medium.  3. Snap the plastic shaft and seal vial tightly with screw cap.  4. Discard the snapped plastic tail.  5. Shake vial up-and-down several times.  6. Place the vial in a biohazard bag and seal for transportation.
