There are no specific contraindications for collecting specimens with nasopharyngeal swabs. However, clinicians should be cautious if the patient has had recent nasal trauma or surgery, has a markedly deviated nasal septum, or has a history of chronically blocked nasal passages or severe coagulopathy.
Ask the patient to take off her mask and blow her nose into a tissue to clear excess secretions from the nasal passages. Remove the swab from the packaging. Tilt the patient’s head back slightly, so that the nasal passages become more accessible. Ask the patient to close her eyes to lessen the mild discomfort of the procedure. Gently insert the swab along the nasal septum, just above the floor of the nasal passage, to the nasopharynx, until resistance is felt .
The swab should reach a depth equal to the distance from the nostrils to the outer opening of the ear. The CDC recommends leaving the swab in place for several seconds to absorb secretions and then slowly removing the swab while rotating it. Your institution may also recommend rotating the swab in place several times before removing it. Ask the patient to reapply her mask.
The virus is composed of a nucleic acid molecule and a protein or only a protein, which is small in size and simple in structure. Because there is no cell structure, the virus itself can not replicate, but the nucleic acid gene into the host cell, with the help of the latter replication system to replicate new virus. After collection of virus samples, in order to maintain the activity of virus samples, prolong the survival time of viruses in the samples, or inactivate viruses with lysate, only some important components of the virus (such as nucleic acid and antigen protein) are preserved and transported in the preservation solution.
The disposable virus sampling tube is composed of sampling tube, cap, VTM preservation solution and / or sampling swab.
[Storage conditions and validity]
Storage conditions: normal atmospheric temperature
Note: after the sample is embedded in the sampling tube, it generally needs to be stored and transported at 2-8 ℃.
The specimens should be transported to the corresponding laboratory within 3 working days after collection, and the storage temperature should be 2-8 ℃; if they cannot be sent to the laboratory within 72 hours, they should be stored at – 70 ℃ or below, and the specimens should avoid repeated freezing and thawing.
