From 2019 so far, the most contact should be the state of the epidemic and nucleic acid testing, it is close to the National Day a lot of partners want to go out to play, so recently many people are asking how long it takes to do nucleic acid testing to come out of the results, today to talk to you.

Rumors on the network "new crown nucleic acid test, half an hour to get the results", "test new crown, only ten minutes" "home can also do nucleic acid test" ...... There are many different opinions, I found some information. Let's take a look at the process and steps needed to go through from the start of the test to the completion of the results.

Guangdong Provincial CDC staff: the new coronavirus nucleic acid test, first of all, specimen collection, followed by laboratory testing, Guangdong Provincial CDC laboratory for the new coronavirus nucleic acid test is based on the national program, using the method is real-time fluorescence RT-PCR. for this method, half an hour is impossible. The well operation time for this experiment must also take about 2-4 hours. This 2-4 hours is usually understood to be the operation time for a single specimen. Laboratories usually operate with batches of specimens, often hundreds of specimens at a time. For the average prefecture-level laboratory size, the entire process of 500 tests takes 8-10 hours. The entire process, the ideal laboratory operation process, means a one-time success; for difficult specimens, there is a need to repeat the test, and even repeated specimen collection, then he will need a longer time. Laboratory testing: specimen processing, nucleic acid extraction, PCR amplification, and report issuance. "All four steps take time. After the specimen is received, the laboratory staff will sort, verify and pre-process the specimen. "Our tests are usually batch tests, with one or two hundred samples. It may take 2 to 3 hours to check the calibration of the samples first, and sometimes there are some special specimens that have to be processed in advance. Then one or two hundred specimens will take 3 to 4 hours to process."

The experts said that after the "whole process" the nucleic acid extraction process really begins, after the nucleic acid extraction also needs to be PCR amplification, also need 80 to 120 minutes. after the PCR, but also to determine the results, data verification and report issuance.

This is why most hospitals or testing facilities only notify the person being tested the next day to get the report. There are also some hospitals that upload to the cell phone on WeChat or APP to download and view.

According to the requirements of the epidemic, if you do not go out to high-risk areas outside the province, you do not need to do nucleic acid testing, generally through the "temperature measurement + health green code" can be, if they belong to the scope of the test, we must follow the relevant requirements of the corresponding disposal before you can go out to work or do other things.

The scope of the "should be tested to the extent possible" include

①, with fever and other suspicious symptoms.

②, himself or family members are close contacts.

③, within 14 days, the person or family members have a history of residence or contact in the risk level of the final draft of the epidemic (including overseas).

④, within 21 days of the community (village) in which they live outbreak.

In addition, the National Day holiday is coming up, so here is a reminder to all of you who want to go out to play to do.

①, wear a good mask, green code travel, the

②, healthy travel, ②, healthy travel

③, do a good job of travel protection.

④, pay attention to food hygiene.

⑤, make a good record of the trip.

⑥. Maintain a sense of protection and monitor your health at all times.
