If the samples are not tested or cultured immediately after collection, they should be stored at 4℃.
After taking samples should be stored in virus preservation fluid and avoid repeated freezing-thawing.
The swab should not be put into the virus preservation solution before use.After sampling, it should be immediately put into the storage solution and tighten the tube cover, sealed in plastic bags or other packaging containers, and stored at the specified temperature for inspection.
[usage]
1. Cut or tear the bag along the slit at the end of the disposable virus sampling tube packaging bag, take out the virus preservation solution and sample swab, and mark the relevant sample information on the label of the preservation tube or paste the barcode label before sampling.
2. Take out the sampling swab (if the swab is packaged independently, please open it from the easily torn mouth at the end of the packaging bag), and use the sampling swab to take samples at the corresponding parts according to different sampling requirements.
A) throat sampling: first press the tongue with the tongue depressor, then extend the swab head into the throat to wipe the bilateral pharyngeal tonsils and posterior pharyngeal wall, and gently rotate to obtain sufficient sampling.
B) nasal sampling: insert the swab head gently into the nasal palate of the nasal canal, stay for a while and then slowly rotate out.For bilateral nostril samples, repeat with another swab.
3. After sampling, quickly put the swab into the preservation tube and break the part of the swab higher than the sampling tube, then tighten the tube cover.
4. The freshly collected samples should be transported to the laboratory within 48 hours at 4℃, and the nucleic acid should be extracted and purified as soon as possible if they are used for the detection of viral nucleic acid;If used for isolation of virus strains, they should be transferred to other medium or medium as soon as possible.If it cannot be sent to the laboratory within 48 hours, it should be stored at -40~-70℃.The samples should be inoculated and separated as soon as possible after they are sent to the laboratory. Those that can be inoculated and separated within 48 hours can be stored at 4℃.Those that cannot be inoculated should be stored at -70℃ or below.
