Receive your results practically immediately and at the best market price, thanks to having our own laboratories for the execution of all the processing and analysis from the taking of the sample to the delivery of results. What is real-time RT-PCR? Real-time RT-PCR, or retro-transcription PCR, is a molecular method that detects the presence of specific RNA from any organism, such as viruses. How does real-time RT-PCR work with coronavirus? A sample is taken using a nasopharyngeal and / or oropharyngeal swab. Various chemical solutions are applied and only the RNA is extracted from the sample. This sample is composed of the viral RNA extract and the patient himself, from which and through a reverse transcription process, using a reverse transcriptase enzyme, it will convert and amplify the RNA into complementary DNA (cDNA) allowing the presence of the virus to be detected. . Why is real-time RT-PCR used? It is currently the reference technique for the diagnosis of the SARS-CoV-2 virus due to its high specificity and sensitivity. This test requires "delicate" processing, so in case of inappropriate treatment (both of the sample, its transport and storage or analysis) it can give rise to erroneous or nonspecific results, although in a very small percentage when the tests are carried out by duly accredited laboratories. Real-time RT-PCR does not allow us to know if someone was infected by the virus, which is important to understand its development and spread, since SARS-Cov2 is only present in the organism with infectious capacity for a certain period. In order to detect, monitor and study past infections, particularly those that have been able to be cured or spread asymptomatically, other methods are required, mainly using seroprevalence control based on serological markers. IgM-IgG | Serological markers for COVID-19 IgG (Immunoglobulin G) and IgM (Immunoglobulin M) are antibodies that the body produces when it comes into contact with some type of invading pathogen. The presence of these immunoglobulins in the blood indicates that the person has had contact with the virus at some point. After this contact, the immune system creates a memory that is maintained in the body for the rest of life.
