Recently, Gibani et al. Indeed, this technology did not require separate nucleic acid extraction and amplification steps. Interest in the use of this type of technology as well as that of the Idylla technology used in the present work are certainly the first to strongly limit the possibility of cross contamination during notably the pre-analytical phases.
For most of the current RT-PCR methods used for SARS-CoV-2 detection, the results are usually obtained after an overall time of an average of 6 hours between the reception of the sample, the sequencing results and the validation of the report by the biologist. But sometimes a longer delay of even upto 24 hours occurs. Importantly, the different pre-analytical and analytical phases need to be mastered by qualified technicians with expert training in molecular biology. Moreover, the results need to be qualified by the biologists for validation before transmission to the physician.
Furthermore, several RT-PCR approaches need to run several samples at the same time for analyses to optimize the use of the same batch of reagents. Thus, it is quite difficult to run one by one the samples on reception in the biology laboratory, which hampers go with the flow.
This may potentially hinder the workflow of the samples and therefore induce a delay in obtaining the results, notably in some urgent clinical settings.
The Idylla test used in this study can be performed within 90 minutes without any risk of contagion due to sample handling and could be done, if necessary, outside a BSL-2 environment in the same way the rapid antigenic test is done for SARS-Cov-2 detection 13 , It is mandatory that the HCWs follow the international guidelines concerning the wear of personnel protection equipment 2 , The results and complete reports can be transmitted immediately in a safe manner to the physicians at the clinical department or even at home via internet from the computer linked to different devices.
It is important to be aware of the occurrence of potential false negative results, notably using RT-PCR approaches Interestingly, in our study the three comparative tests did not have the exact same gene target design. However, despite the different designs we obtained a high level of concordance for these comparative tests.
Moreover, when evaluating the viral load, which can be indirectly estimated from the different CT values, the results showed relatively good concordance between the different tests.
This information may be of considerable interest to the physician since the severity and the prognosis of the disease may correlate with the viral load, independently of the associated risk factors According to Jiang et al. First, these techniques are mainly associated with a low sensitivity of single tests and the optimization of primer design and reaction conditions.
The sensitivity was The second disadvantage of RT-LAMP is that the process for designing primers and probes capable of targeting specific gene sequences can be complex As a result, primer optimization might be limited. Access your results online or print from our patient portal within 30 mins — 2 hours. Rapid Antigen Test. Testing for Travel Clearance. RT-PCR testing is used for a majority of state and international travel guidelines and means that you need this specific type of test before you can effectively travel.

What is the difference between rapid testing and antibody testing? Insurances Accepted at Instant Urgent Care:. Full Insurance List. Regardless of the test used, you should self-isolate or quarantine while you wait for the results. A positive test result means that you most likely have COVID now and should self-isolate: stay home, separate yourself from others, and take precautions to reduce the risk of spreading the virus, including using a face covering and practicing good hand hygiene and physical distancing.
If your symptoms get worse, you should contact your local health care provider by phone. Once all of your symptoms have resolved and you have completed your isolation period as directed by your health care provider, you do not need to be tested again.
If you live in a household with other family members, it is important that your family also take precautions to reduce their risk of being infected and further spreading the virus. All family members who experience symptoms of COVID should also be tested and should self-isolate until their symptoms have resolved. You should continue to practice good hand hygiene, physical distancing and wear a face covering.
This is especially important if you have symptoms because it is possible you have the virus but the test did not detect it.
If you believe you have tested negative and may, in fact, be infected, speak to your health care provider about being tested again. Yes, either because the test did not detect the virus or because you were infected after you took the test.
If you have tested positive, it is critical that you self-isolate so to ensure you do not spread the virus to others. To learn more about testing facilities in your area, please contact your local Aga Khan Jamati Health Board or government health agency for details.
