We need scientific methods to diagnose or rule out whether a patient is infected with the new coronavirus.

Actualmente existen métodos de prueba de diagnóstico específicos y autorizados., y solo hay uno: prueba de ácido nucleico.
1. Principles of conventional nucleic acid detection

Direction: Método genético: RT-PCR Reverse transcription polymerase chain reaction Test object: Virus gene itself Accuracy: Maximum time: a few hours to a few days Advantages: High accuracy, is the only basis for diagnosis at present Disadvantages: Long time, High barriers to professional operation

The new coronavirus is an RNA virus that can replicate itself when it enters and infects the human body. As long as the person is infected, there must be a virus in the body. But because the virus is too small to be seen under the microscope, it cannot be confirmed directly by observation.

Throat swab sample collection.

Everyone should be familiar with the term “hisopo de garganta”, which is the primary source of samples for new coronavirus testing. Simplemente pon, it is to use a plastic stick to reach the patient’s throat and wipe it, collect some respiratory fluid, then package it, refrigerate, and send it to the laboratory for RT-PCR testing.

Esto podría deberse a una infección asintomática., experts soon discovered that the results of the throat swab samples were inaccurate and the probability of false negatives was high. Por lo tanto, in different countries or regions, front-line medical workers may also collect samples such as nasal swabs, sputum, and feces for testing.
