Characteristics of sampling swab products:

1. It has extraordinary water absorption capacity, which can increase the number of samples collected on its surface from 20% of traditional sampling swabs to 60%.

2. The release rate of the collected samples is more than 90%, so as to ensure the high reliability of the results.

3. Different preservation solutions were selected for different specimen types.

4. The plastic rod has a unique breakable design to facilitate specimen transportation.

5. Ethylene oxide sterilization, irradiation sterilization, independent packaging.

Iclean gene sampling series flocking DNA oral test pieces are specially used to improve the amount and quality of genomic DNA in oral test piece cells. Oral cell sample is a good non-invasive collection and detection method instead of blood. Combined with icleanhcy’s series of DNA separation and stabilization kits, it can quickly collect high-purity and complete DNA samples.

DNA flocking swab is suitable for human and animal use. It has advantages over other DNA samples in design. Its unique sample matrix and rapid release interface are more conducive to efficient cell collection and maximize DNA yield. The test piece has been sterilized with ethylene oxide and passed the detection of human DNA contamination.

The spread of the covid-19  is continuing worldwide. Although the global scientific and medical circles are making every effort to fight the epidemic, it is difficult to predict how the epidemic will develop in the future, and its impact on social development has appeared in many aspects.

Currently, COVID-19 cases are over 220 million.

Currently, COVID-19 cases are over 220 million.

In order to fully control covid-19, the general screening of local areas shall be carried out if necessary.

After identifying the detection object, how to detect it?

1、 What specimen to choose?

According to the recommendations of the American infectious diseases association, the following specimens were used:

The sensitivity of simple oropharyngeal swab may not be enough, so it is relatively easy to miss diagnosis.

The sensitivity of alveolar lavage fluid is the highest, but it is obviously not suitable for universal screening.

Nasopharynx swabs and other operations should also be standardized.

Improper operation may make the quality of collected samples not high, thus increasing the risk of missed diagnosis.

2、 Select the time of detection

It is very important for COVID-19 to measure RNA and choose the right time. One analysis included 7 studies, including 2 unpublished reports, to evaluate the detection efficiency of RT-PCR at different time points after exposure to virus :

On the day of exposure to the virus, the possibility of detecting viral RNA is almost zero;

On the fifth day after exposure, that is, the first day after infection, the detection probability was 62%

About the 8th day after exposure, i.e. the 4th day after infection, the probability of detection was 80%

On the 21st day after exposure, i.e. the 17th day after infection, the detection probability was 34%

In conclusion, exposure to COVID-19 may require multiple tests to avoid missed diagnosis. However, it is not recommended to repeat the test within 24 hours of the previous test; The interval between two tests shall be at least 24 hours.

After 28 days of exposure to the virus, if the infection has not been diagnosed, it is not necessary to continue the detection; At this time, it is almost certain that it is not infected.

Nucleic acid detection throat swab  sampling process

The COVID-19 nucleic acid was novel coronavirus, which was collected from sputum or lower respiratory tract by real-time fluorescent RT-PCR. If positive, the new coronavirus could be diagnosed. This is the basis for the diagnosis of new type of pneumonia. In addition to detecting the nucleic acid of the virus, it can also detect whether the virus in the specimen is highly homologous with New Coronavirus. If so, it can be diagnosed as New Coronavirus pneumonia. The virus is highly infectious and has the characteristics of human to human transmission, but the virus is sensitive to temperature and sunlight and ultraviolet rays.
