Antigen Test for COVID-19: Reduce Transmission Fast

HiLab’s antigen test detects the presence of SARS-CoV-2 at the greatest transmissibility stage. The result is fast and the report signed by a health professional arrives directly on the phone in 25 minutes.

What is a Remote Lab Test?

Remote Lab Test (RLT) is an exam that can be performed outside a clinical analysis lab.

HiLab’s antigen RLT detects the proteins of the SARS-CoV-2 nucleocapsid and has the distinction of offering a double-checked results by artificial intelligence and by one of our experts.

Fast virus detection

From the 5th to the 12th day after exposure or from the 1st to the 7th day after symptoms onset

Result in 25 minutes

The result of HiLab’s antigen test comes out in 25 minutes, making it ideal for rapid testing in clinics, pharmacies, healthcare facilities, events, and other places.

Ideal for the transmission period

The antigen test has a high correlation with the transmission period of the disease, contributing to the identification and isolation of transmitters.

Used for contact tracing

Antigen testing is indicated for the contact tracing strategy, which is essential in combating the pandemic. With it, it is possible to interrupt the transmission chain by testing symptomatic and asymptomatic individuals.

How did we reduce COVID-19 cases here at HiLab using the antigen test?

Asymptomatic people are also transmitters of the coronavirus. Knowing this, we didn’t think twice about creating our mass testing strategy to reduce COVID-19 transmission here at HiLab.

  • In just one month of testing with the antigen test,
    we reduced by 61% the cases of COVID-19 among our employees.
  • We identified that for each symptomatic case
    there were two asymptomatic cases.

Service differentials


HiLab exams undergo a double verification process by Artificial Intelligence and clinical analysis specialists

24/7 technical support

Our lab is available 24 hours a day. When hiring our services, you have the support of experts to solve all your questions about HiLab exams.

Report signed by a health professional

A healthcare professional from the HiLab lab digitally signs your reports.

Training and monitoring

We offer complete training on how to carry out the collection, connect the equipment, as well as guidance on the exams.

Data intelligence

The entire HiLab system works connected to the internet, which allows real-time updating of a database that shows all information about the exams performed.

Differentials for the patient

Affordable price

The antigen test is cheaper when compared to the PCR test, even if the reliability of the result is the same.

Detects virus during transmission

The antigen test has a high correlation with the period of transmissibility of the viral infection. Therefore, it is ideal to identify who is transmitting the virus to other people.

Waiting time

The result comes out in a few minutes, allowing the patient to continue the medical appointment on the same day or leave the health facility with the result in hand.

Humanized collection

The collection of the nasopharyngeal sample is made using a thinner and more comfortable cotton swab.

Indications and technical specifications of the antigen test

HiLab Antigen Remote Lab Test (RLT) is indicated from the 5th to the 12th day after exposure or from the 1st to the 7th day after symptoms onset.

This test uses specific monoclonal antibodies to detect viral nucleocapsid protein, with high sensitivity and specificity.

Method: Immunochromatography
Type of sample: Nasopharyngeal secretion
Total exam time: 25 minutes
Specificity: 98.8%
Sensitivity: 93.7%
Accuracy: 95.7%

How to interpret the HiLab Coronavirus Antigen Test result


The result indicates that the presence of antigens of the SARS-CoV-2 virus was not detected in the analyzed nasopharyngeal secretion sample. Suggests absence of coronavirus infection.


The result indicates the presence of SARS-CoV-2 virus antigens in the analyzed nasopharyngeal secretion sample. It suggests coronavirus infection.

Important: the result must be interpreted by a physician who must consider some factors such as clinical manifestations, the onset of symptoms, and complementary exams.

Discover our other solutions for COVID-19

In addition to the antigen test, HiLab also presents other solutions for a fast diagnosis of the infection: the IgM and IgG RLT - which detects the antibodies - and the PCR-LAMP test, which detects the genetic material of the virus.

Frequently Asked Questions

What is the COVID-19 antigen test?

Antigen testing detects the SARS-CoV-2 antigens, that is, the viral nucleocapsid proteins.

What are the differences between the RT-PCR test and the antigen test?

The antigen test emerged as a way to identify the infection as quickly as possible. Like the RT-PCR exam, it is indicated for the initial phase of the disease. However, the result comes out in just a few minutes and not in 2 to 3 days like the RT-PCR exam. The RT-PCR test detects the genetic material of the virus while the antigen test detects the viral proteins.

Why is antigen testing important?

Tests that detect SARS-CoV-2 while people are transmitting the virus are important tools in fighting the pandemic. In addition, antigen testing has a much more affordable value compared to RT-PCR.

You have the chance to leave the health facility with the result in hand and go into home isolation immediately, which is essential to reduce the transmission of the disease.

Does the antigen test detect if the person has already had COVID-19?

No. The antigen test only assesses whether the person has COVID-19 at the time the test was performed. The test does not assess whether the person has had the infection at any time. For this purpose, we recommend the HiLab Coronavirus IgM and IgG test, which detects the presence of antibodies produced by the body to fight the infection.
