How does your nucleic acid test report be born?Reporter witnessed the whole process

From the sample swab to the mouth, to the results of the Health Tong of Tianfu, after a few hours of waiting, the "green code in hand" was finally ushered in. How many links will this seemingly relaxed QR code go through?

Nucleic acid testing is the most critical part of case screening, and it is also the primary criterion for diagnosis of new crown pneumonia. From September 1st, Chengdu will conduct a whole nucleic acid test in the city. Facing the surplus sample quantity and urgent detection time, from samples, samples, to receiving, testing, nucleic acid laboratory is undergoing a confrontation with the virus and running with time.

On September 1, Red Star Journalists walked into the Second People's Hospital of Chengdu and witnessed the process of reporting a nucleic acid test report.

Nucleic acid sampling

Sample and sample:

Dynamic adjustment, the whole process cooperates with each other

At 17 pm on September 1st, the outpatient department of Chengdu Second People's Hospital, the queue crowd quickly moved forward. According to the three categories of green code, yellow code, and entering Sichuan code, the team is orderly to their own exclusive windows.

Nucleic acid sampling site

One of the "Bai" sitting in one of the green codes is called Liu Yanxia. She is a respiratory nurse. She works from 16 o'clock to 24 o'clock. Disinfection, packaging, sampling, and installation, smooth movements are sampled for more people in a short period of time. She told the Red Star journalist that the citizens of the lineup of nucleic acids on that day have greatly increased, and the sampling process has also been dynamically adjusted. At the front end of the team, a staff member is responsible for scanning the code in advance, so that the subsequent sampling speed will be greatly improved.

Behind her, another staff member counted the samples in real time, and packed into the biological safe transport box, and transferred it to the specimen transport staff. Zhang Xiaofei, wearing a blue isolation dress, carefully took the sample from the back door and window, and took a quickly but stable step to take the specimen receiving place.

Specimer transport staff is sending samples

"We arrange different sample nodes according to different requirements. This is very important to ensure the smooth flow of the whole process." Paper Yong, Secretary of the Party Branch of the Inspection Division and Director of the Clinical Medical Examination Center The personnel, the personnel of the Sichuan code, the patients in the hospital in the hospital, and the green code personnel who are willing to check the inspection to determine the inspection node according to the severity. For example, the two principles were clarified for patients with fever: the first is a special person for inspection, and the second is half an hour. The yellow code personnel and the entry Sichuan code personnel are delivered at one hour.

"The timeliness of nucleic acid detection is very critical. For the people and the government, they must grab this key point in order to ensure that the sample is delivered to the laboratory. Essence

Receive and detection:

Classification, processing, number, and shelter by severity

In the specimen passed the window, Zhang Xiaofei handed the sample into the house. An attractive detail is that the process of sending the sample is always a "single cycle". The staff did not "go back" and did not even step into the room in the upper and lower links. Such one -way channel runs through the entire nucleic acid detection process.

While sending samples, an invisible information transmission channel is also running at high speed.

When the laboratory receives ordinary samples, it is necessary to take a certain time through the number of specimens to collect the number of specimens. At present, the nucleic acid testing of the Second Municipal Hospital has achieved information control. After the sampling point is scanned, the patient's information and sampling time are all transmitted to the background in an instant, and the electronic record table is directly formed. This is not only fast, but it is not easy to make mistakes.

Clinical Molecular Laboratory

The molecular laboratory is located in a separate small building, and the personnel entering and leaving need to be worn in the "semi -pollution zone". This is the crucial laboratory testing link.

According to the importance of sampling specimens and the requirements of the timeliness, the staff must first process the specimen in front of the specimen, and classify, process, number, and on the shelves in accordance with the severity. Looking at the glass windows, medical staff from clinical adjustment are focusing on numbers, sorting specimens and medical waste. In this unprepared environment, they are wearing thick protective clothing and can only communicate with colleagues in other rooms with intercom. When they are busy, they will be busy until two or three in the morning the next day, and then from the next group of colleagues. succeed.

Medical staff is conducting specimens and nuclear collection work for nucleic acid testing

After the previous treatment is completed, the nucleic acid sample will be extracted through two links: extraction and PCR amplification, respectively. Among them, the extraction is to remove impurities and eventually form a purified nucleic acid; the amplification is to expand the virus index level, so that it is easier to find in the detection.

Through the glass, you can see that the green curve symbolized on the instrument display gradually rises. During the interview, Paong continued to remind that these two links were also the most dangerous. The "big white" in the room was "positive" with the virus at this moment.

When the expansion is over, the results of the nucleic acid detection come out. But there is "last mile" from citizens' brushing results on their mobile phones.

According to Baodong, the laboratory staff is responsible for the review of the results of the expansion and issued a report, which will be automatically uploaded by the system; when the information is abnormal, for example, when the identity information does not match, the information department needs to adjust from the Tianfu Health Platform. Take relevant information, finally check and upload manually. After the whole process, from samples, samples, to receiving and testing, it is considered a closed loop.

Newly added over 100,000 people in a single day

I haven't returned home for ten consecutive days to rest

How much time does the whole process take?

"Under the ideal circumstances, it takes 4 hours." Baodong said that many citizens hope that the nucleic acid detection results can accelerate, but after the whole process is completed, 4 hours are the fastest speeds. If you encounter review, information upload, etc. The problem needs to be longer. Especially after the city's nucleic acid testing in the city, the laboratory should undertake the heavy task. Taking the Second Municipal Hospital as an example, the hospital laboratory department will undertake the task of social screening on the basis of the sampling of the patients and employees and outside the hospital. The detection volume. Paong Yong, Secretary of the Party Branch of the Second Hospital of the Municipal Second Hospital and Director of the Clinical Medical Inspection Center

"Increase the sample, the workload required may increase geometrically." Paong Yong said that the laboratory is usually responsible for nucleic acid testing 12 people. Currently, in accordance with the principles of three shifts and axis, 12 people per shift, and from from the class, and from from the class, and from the class, and from the shift, and from the shift, it is 12 people, and from the class, and from the shift, and from the class, and from the shift, it will be from 12 people. Other departments have regulated medical staff to do the front -end work to ensure that "people are stopped."

Under the pressure, the staff of the department did not have a normal life. Some father died and did not go home, and some weddings were not handled. Even Bao Yong himself had not returned home for 10 days. In his office, he couldn't even see a folding bed, because even if he was late, he couldn't sleep completely, he could only lie on the table for a while, and was wake up by the phone to deal with the next job. The laboratory that is not resting for 24 hours is always on.

"We can rest when the epidemic disappears. We are a firewall in the epidemic." Ba Yong said with emotion that as a party member, he had no complaints to complete the task of the party and the people. He called on citizens to understand and be patient with a little more about nucleic acid testing, and look forward to returning to normal life as soon as possible.
