We accompany people and companies to control and mitigate the effects of the pandemic through the latest technologies in the diagnosis of SARS-CoV-2.

Types of tests available

PCR

It is the most reliable test to detect the virus. It is presented as a nasopharyngeal sample that requires laboratory processing.

It is a saliva sample test that requires further processing in the laboratory. Ideal for self-taking at home.

It is a virus detection test with results in 15 minutes and reliability comparable to that of a PCR.

It is a laboratory test or rapid test through a blood sample that allows the detection of antibodies indicative of a past infection.

Virus detection: PCR

It is a type of diagnostic test. It is a validated test for the detection of the SARS-CoV-2 virus that causes the COVID-19 disease.

It is based on the direct detection of the genetic material of the virus (RNA) and is the most reliable genetic test of all the techniques.

It allows identifying infected patients shortly after the infection has been established (48 hours before having symptoms).

PCR is performed by taking a nasopharyngeal sample in a smear made by healthcare personnel or by means of a validated self-sampling protocol.

The analysis of the sample must be carried out in an approved laboratory.

  • It is a highly sensitive and specific test that yields a low number of false negatives.
  • It is considered the most reliable test for an acute / early diagnosis.
  • Results in 24-48h

Virus detection: PCR in Saliva

It is a type of diagnostic test. It is a validated test for the detection of the SARS-CoV-2 virus that causes the COVID-19 disease.

It is based on the direct detection of the genetic material of the virus (RNA) and is the genetic test that has the highest reliability of all the techniques.

It is a test with quick and efficient sampling: the saliva is collected in a jar and the collection is organized at home.

It allows identifying infected patients shortly after the infection has been established (48 hours before having symptoms).

The sample made for the test is from saliva, which reduces the complexity in taking it, and can even be done without the intervention of health professionals.

It is recommended not to eat or drink in the 15 minutes prior to collection of the sample and it is preferable to do it first thing in the morning.

The kit sent home contains all the elements to carry out the extraction and for subsequent shipment to the laboratory. Includes an envelope to send the sample to the laboratory at no additional charge and safely. A courier will pick you up at your home.

Remove the blue cap

The blue cap is removed. The cup is not removed from the inside of the tube containing the “gum”.

Extract the “gum”

The cotton “gum” is extracted from the cup by touching only the end

Chew cylinder

The cotton ball is chewed until it is soaked in saliva

Enter the cotton

The cotton cylinder is returned to the cup inside the tube

Close the tube

The tube is closed tightly with the same blue cap

  • Reliability>95%
  • Without the intervention of a healthcare professional
  • Only one available for self-intake of saliva
  • Complete kit for sample collection and shipment to the certified laboratory of analysis
  • Results in 24h *
  • Clinical laboratory report**

*Always counted on weekdays. The delivery of results can
take up to 72 hours in exceptional cases or in tests requested at
home.
**The laboratory will deliver a clinical report with the positive or
negative result of the analyzed sample. This report will not refer to the
client, since the sample extraction process is confidential
as it is carried out in a private home without the presence of a physician.

Virus detection: Rapid Antigen Test

It is a type of diagnostic test indicated for the detection of an active infection of the COVID-19 virus. It detects proteins, called antigens, on the surface of the virus rather than its genetic material so it is faster and can be done en masse.

Its main advantage is that it offers results in just 15 minutes.

  • Sensitivity 93.3%
  • Specificity 99.4%
  • Concordance 97.9%

The rapid antigen test is a test more focused on the diagnosis of COVID-19: it is used to detect individuals with an active infection and not those who have already passed the disease.

It is performed through a nasopharyngeal sample, the same as PCR.

  • Result in 15 minutes
  • Does not require reading instruments
  • It can be performed at the onset of infection symptoms, with mild symptoms, or in infected but asymptomatic people

It is indicated for:

  • People with compatible symptoms, not a substitute for CRP.
  • Close or occasional asymptomatic contacts.
  • Population screening to detect asymptomatic carriers in the contagious phase.

It is not indicated for:

  • Receive reports on the state of health.
  • Reports for travel or access to other countries.
  • Certification for preoperative.

Test to detect immunity: serological tests

The serological test is based on the detection of IgG and IgM antibodies generated by the patient’s immune system after infection occurs.

It allows the identification of infected patients from 5 days after the infection has occurred.

Due to this long window period, its isolated use as an acute / early diagnostic tool is not recommended since it can lead to a high number of false negatives.

It is done through a blood sample.

The technique used in the quantitative test is the microplate enzyme-linked immunosorbent assay (ELISA). It does not only give a result of positive or negative, but it gives the value (amount) of antibodies detected. This helps to define where the patient is on the immunity curve.

It requires a blood draw and laboratory evaluation. Results in 24-48h.

The technique used in the qualitative test is the qualitative detection of differentiated IgG and IgM antibodies by lateral flow chromatographic immunoassay in samples of a few drops of blood with results in 15 minutes without the need to send a sample to the laboratory.
