Nasopharyngeal Flocked Swab for Sample Collection
Flocked Swabs are ideal for collecting large amount of cells and rapid solution of the specimens instantly release the cells into the cells into the transport medium. Flocked swabs utilize innovative nylon fibre technology to provide outstanding sample collection and release. Nylon fiber swab that allows a better clinical sample collection and the following immediate release into the liquid transport medium. It has a plastic shaft with"breakpoint" to allow the swab break into the test tube and successive collection by screw"capture" cap after the tube closing.
What is the key to the collection of nucleic acid test samples?
Whether it is to collect the nasopharynx swab or the oropharynx swab, the depth of collection is the key. The collection of the nasopharynx swab did not reach the depth of the nasal cavity. Most of the cells that may be collected are virus-free cells, which may cause "false negative".
Oropharyngeal swab
The tissue cells collected from nasopharynx swab and oropharynx swab are anatomically different.
What is the correct procedure for collecting nasopharynx swabs?
1. The sample holder holds the swab with his right hand (plastic rod swab of polypropylene fiber head), and holds the swab with his left hand on the head of the subject to fix it.
2. Make the swab with the top slightly bent down enter from the front nostril, and slowly penetrate backward along the bottom of the lower nostril.
3. When the top of the swab reaches the posterior wall of the nasopharynx (there is a touch of the wall), leave the swab for a moment (about 3 seconds), and then rotate it gently for a circle, and slowly take out the swab.
4. Take another plastic rod swab with polypropylene fiber head to collect the other nostril in the same way, immerse the two swabs in the same tube containing 3ml virus sampling solution, discard the tail and tighten the tube cover.
5. After packaging according to the biosafety requirements, it shall be transported to the laboratories of centers for Disease Control and prevention at all levels as soon as possible for virus nucleic acid detection.
