Nucleic Acid

Behind a Nucleic Acid Test report, a tribute to a group of ” behind-the-scenes heroes” who have paid silently.

Nucleic Acid Sample Collection Method

Throat swab

Nasal swab

It is believed that most people have done throat swabs and nasal swabs. In addition to throat swabs and nasal swabs, there are also some sputum samples and stool samples. It took several hours for the COVID-19 testing work from the completion of the Nucleic Acid Test to the receipt of the report. Next,I will take you to understand how the sample analysis process is.

Before Sample Analysis

Sample Collection
In the latest version of the COVID-19 pneumonia diagnosis and treatment plan (the sixth version), the types of samples mentioned include respiratory samples, blood samples, stool samples, etc. Specimen collection is carried out by clinical specialists or nurses under the conditions of personal Three-level Biosafety Protection.

Sample Transport
The COVID-19 Specimens are transported to the laboratory through central transportation, generally within 2 hours. The COVID-19 Virus specimens should be transported by a separate person and should not be mixed with other items. Transport personnel need to be transported under secondary biosafety protection conditions.

Sample Reception
The COVID-19 Specimens are high-risk specimens, and it is recommended to have signatures in the collection, transfer, and reception links for retrospective. Operators are required to have secondary biosafety protection.

Sample Detection and Analysis

The COVID-19 Nucleic Acid Test Samples are sent to the laboratory through central transportation, and the entire test work needs to be carried out in the laboratory of microorganism P2+.

Sample Preparation

The samples are identified and numbered appropriately by the staff, and the samples are inactivated for about 50 minutes after receiving the samples to ensure the safety of the samples.

After inactivation, the sample is centrifuged. When the sample is centrifuged, the ventilation facilities are turned on, and the operator can put the centrifuge tube into and out of the rotor in the Biological Safety Cabinet as much as possible.

The centrifuged samples are opened in the Biological Safety Cabinet for the opening of the lid and the overall processing of Nucleic Acid Extraction.

(This step is the most dangerous step in the entire Nucleic Acid Detection process. It can be said that it is facing the virus at zero distance. The Biological Safety Cabinet establishes a protective barrier for the detection personnel, which plays a crucial role).

Amplification Analysis

In the reagent configuration room of the laboratory, configure the corresponding PCR reagents. In the sample preparation area, the sample is added to the prepared reagents, and the prepared sample is transferred into the fluorescence quantitative PCR instrument in the amplification analysis area for Nucleic Acid Amplification Detection, and the result is obtained to determine whether it is positive.

(The processing and extraction of the Nucleic Acid Amplification Test of the COVID-19 specimens are all high-risk processes, and individuals must operate in the three-level biological safety protection and Class II Biological Safety Cabinet).

Test Results and Upload

After the detection, the work has not yet been completed, and the information data processing personnel also need to sort out the sample data and report it in time.

Generally speaking, the whole experiment process takes about 4 hours, if the sample volume is relatively large, this process time will be extended.

Work together to fight the Epidemic

Heal Force COVID-19 Nucleic Acid Detection Solution and Sample Detection application scenario provides an efficient and flexible emergency solution for Nucleic Acid Detection.

In this tribute, a group of behind-the-scenes heroes who worked silently, in the laboratory where the masses could not see, had close contact with the virus, and carefully screened virus with a pair of eyes. Race against time, work around the clock, and act as a strong backing for epidemic prevention and control. They are the laboratory inspectors behind the Nucleic Acid Detection work.
