Rapid Blood Test

The rapid blood tests allow us to evaluate the clusters of these different types of immunoglobulins and to know if it is protected against the Sars COVID-19 by the development of antibodies. The antibody levels start to increase while the disease progresses.

Once an antibody is produced as a response to a specific agent, the next time this agent enters the body, the immune system identifies it and "remembers" the defense response, producing the same antibodies that were used the last time.

The rapid tests that we have analyze the IgG and IgM levels to identify the existence of active immunoglobulin (IgM) As a response to the infection in progress (Covid-19) (an acute infection). Or if there is a "memory," immunoglobulin (IgG) created against Covid-19, which will imply that you had the disease, which means you now have a defense response in your immune system.



First curve: it refers to the infection by the virus. This is called the period of viremia. The second curve (soft blue): refers to the elevation of the IGM antibodies. Third curve (red) refers to the IGG antibodies. 

This shows the period, or stage of the disease in which each of the tests can detect the Covid-19 virus.

It is important that the usefulness of each test is identified for each stage of the disease. Normally, Covid-19 can have an incubation period of up to 14 days and remain infectious for up to another 21 days. This is the reason why isolation is recommended to the patient in order to avoid spreading the disease

Considerations to perform the fast test

  • The test must be scheduled by an appointment
  • An official result is handed over, with a quantity response, such as "POSITIVE" or "NEGATIVE."
  • The results include an interpretation guide; however, if you wish to see a physician afterward, we will gladly schedule an appointment for you.
  • A medical order is not required for you to take the test.
  • The results will be handed over to you on that same day.
  • If you wish to take the amplified test after taking the fast test, we can schedule the appointment, as long as you are still in the 24-hour range of the fast test, you will only need to pay the difference.
