Sample sampling: collecting nasopharyngeal swabs from patients
The samples currently used for H7N9 testing are mainly nasopharyngeal swabs from patients.
When collecting nasal swabs, the patient's head is kept as still as possible, the polyester head swab is gently rotated and slowly inserted into the patient's nostril to the jaw, staying for a few seconds to absorb the secretion, the swab is gently rotated and removed, placed in the sampling tube, the plastic handle of the hand contact area is broken, so that the swab is immersed in the sampling solution, and the cap is screwed on.
Transportation process: sealed, refrigerated storage
Samples in the transport process to pay attention to sealed refrigeration, to ensure the safety of the sample, not lost, leakage and other phenomena, so as not to cause pollution of the environment. Experts say that the extracted samples need to be sealed and generally placed in special transport boxes for refrigerated storage at temperatures between 4°C and 8°C.
The time required for testing: rapid testing 3-5 hours to produce results
