Premier Li Keqiang in the State Council meeting required to strengthen biosafety risk prevention premise, to ensure that the national three-tier general hospitals, infectious disease hospitals, disease control agencies at all levels and 1 county hospitals in the county with nucleic acid testing capabilities before autumn and winter.
To mobilize the strength of all parties to accelerate the short detection time, high sensitivity, easy to operate the product development market. This is an important support for 'early detection' of epidemic prevention and control, and helps make scientific epidemic prevention more efficient.
How long is a test valid?
As mentioned above, the nucleic acid test can detect whether the subject is infected with the virus at the moment. There is no guarantee that a new coronavirus will not be transmitted next. However, for operational purposes, nucleic acid test results are valid for a certain period of time. At present, the validity period is basically set at 7 days everywhere.
Does the nucleic acid test hurt? In fact, the whole process of nucleic acid testing is very fast. Nowadays, the nucleic acid test is to collect a throat swab, which is to open the mouth to take a secretion from the mouth, and there is usually no pain. There are no dietary restrictions before the sample is taken, and drinking and eating are not affected.
The specific steps are as follows.
Step 1: The tester rinses his or her mouth with water first.
Step 2: The sampling swab is placed in saline and moistened to dip more cells.
Step 3: The sampling staff uses a tongue depressor to assist in applying the sampling swab to the bilateral tonsils and posterior pharyngeal wall repeatedly 2-3 times. Step 4: Put the sampling swab into the collected plastic tube, i.e., virus transport medium, and break the swab stick so that it is fully placed in the tube.
Step 5: Screw the cap tightly, mark the specimen number, name and other information, and affix the corresponding serial number of the medium on the acceptance slip.
