Specimen Collection and Storage
1.This product can be used for nasopharyngeal or oropharyngeal swab samples. Nasopharyngeal swab specimens are recommended strongly.
2.Protective measures shall be taken when collecting specimens and the specimens shall be collected in accordance with the licensed collection techniques.
3.Before collecting specimen, ensure that the specimen tube is sealed and the extraction buffer does not leak out. Then tear the seal off the tube pre-filled with buffer and gently place it on the tube stand.
4.Collection of Specimens:
Oropharyngeal specimen: With the patient’s head slightly lifted up, and the mouth wide open, the patient’s tonsils are exposed. With a clean swab, the patient’s tonsils are gently rubbed back and forth at least 3 times, and then the patient’s posterior pharyngeal wall are rubbed back and forth at least 3 times.
Nasopharyngeal specimen: Let the patient’s head relax naturally. Turn the swab against the wall of the nostril slowly into the nostril, to the nasal palate, and then rotate while wiping and remove slowly.
Treatment of Specimen: Insert the swab head into the extraction buffer after specimen collection, mix well, squeeze the swab 10-15 times by compressing the walls of the tube against the swab, and let it stand for 1 minute to keep as many samples as possible in the specimen extraction buffer. Discard the swab.
5.Swab specimens should be tested as soon as possible after collection. Use freshly collected specimens for best test performance.
6.If not tested immediately, the swab specimens can be stored between 2-8°C for 4 hours after collection or be stored at room temperature for 1 hour. If long-term storage is required, it should be kept at -70℃ to avoid repeated freeze-thaw cycles.
