Nasal swab pcr test COVID-19 Antigen Rapid Test Kit
Detection of COVID-19 by nasal swab PCR is an accurate and reliable method. Positive detection means you may have SARS-CoV-2. Negative detection means you may not have SARS-CoV-2 when testing.
In order to ensure your safety, if you have symptoms of COVID-19. Or people who have been exposed to the virus and tested positive should be tested.
What is the symptom of COVID-19?
If you have the following symptoms,if you have the following symptoms, please buy covid-19 antigen rapid test kit immediately or go to a nearby hospital for PCR test.
1.Fever;
2.General fatigue;
3.cough;
4.Dyspnea or even respiratory failure；
5.Nausea;
6.vomiting;
7.abdominal pain;
8.diarrhea;
Symptoms of New Coronavirus pneumonia are not necessarily typical, and some patients may not have clinical manifestations at the early stage of New Coronavirus infection. Then clinical manifestations will appear, that is, “asymptomatic infection” in incubation period.
In other words, try to avoid activities in places with crowd gathering, closed space and poor ventilation.
What is nasal swab PCR test？
Polymerase chain reaction (PCR) uses a piece of DNA as a template. Then, with the participation of DNA polymerase and nucleotide substrate, the DNA was amplified to a sufficient number for structural and functional analysis.
Scientists use PCR technology to amplify a small amount of RNA in the sample into deoxyribonucleic acid (DNA) and replicate until COVID-19(if present) is detected.
What should we pay attention to before doing nucleic acid test？
1.Try not to eat 2 hours before sampling to avoid vomiting.
2. Do not smoke, drink, drink water or chew gum 30 minutes before sampling.
3. The tester needs to wear a mask correctly and remove the mask before testing;
4. Wear it immediately after testing, and prepare a spare mask for easy replacement at any time after pollution.
5.When you feel sour and itchy in your nose or sneeze, you can immediately cover it with a paper towel or elbow.
Before collecting nasopharyngeal swabs and before being tested, the collection personnel shall be informed whether they have relevant past medical history. For example, history of nasal surgery, history of deviation of nasal septum, blood diseases, throat diseases, etc
How long will we know the pcr test results？
The test results of sampling in the morning are generally available from 18:00 to 19:00.
The detection results of afternoon sampling can generally be queried around 22:00.
What’s the difference between the PCR and antigen tests for COVID-19?
Polymerase chain reaction (PCR): PCR is the most reliable and accurate method to detect active infection. PCR tests usually give results in a few hours.
Antigen detection: detect protein fragments on the surface of covid-19. Antigen detection usually takes only 15 to 30 minutes.
How can we prevent COVID-19?
Firstly, keep good personal hygiene habits, wear masks when going out, wash hands frequently, clean the room, and wipe the floor and other furniture with disinfectant. Second, disinfect your hands with 75% alcohol every time you go out and go home, reduce the number of times you go out, and wear qualified masks. And the diet should also be light, do a good job of physical exercise and enhance personal physique.
Most importantly, if our conditions permit, we should vaccinate and conduct multiple nucleic acid tests.
If our Nasal swab pcr test results are positive,what should we do?
If our test results are positive, don’t be afraid. We should wear masks and go to the nearby Hospital for follow-up in time.
Repeat the nucleic acid test.Don’t be afraid and hide the test results. Timely medical treatment is the best choice.
