Antigen test

Antigen testing for Covid-19 detects certain proteins in the virus and helps to diagnose an active infection of coronavirus.

In this type of diagnostic test used a swab nasal or nasopharyngeal to take a sample of fluid from the nose or throat.

The rapidity with which this method can give results makes it one of the best alternatives in terms of comfort and safety of those who undertake the study.

By having a lower price in comparison with other tests, such as PCR to detect the genetic material of the virus, are practical to have quick results.

PCR test

The evidence of reaction (PCR polymerase chain reaction) is a fast and highly accurate to diagnose certain infectious diseases and genetic changes. The tests detect the DNA or RNA of a pathogen (the organism that causes a disease), or abnormal cells in a sample.

• The DNA is the genetic material that contains the instructions and the information of all living beings
• The RNA it is another type of genetic material. Contains information copied from DNA and is involved in the production of proteins

The majority of viruses and other pathogens contain DNA or RNA.

Unlike many other tests, the PCR can find signs of a disease in the early stages of the infection.
