IgM and IgG Antibody test for COVID-19
HiLab’s antibody remote lab test detects IgM and IgG antibodies produced by the immune system after contact with the coronavirus (SARS-CoV-2). The result is fast and the report, signed by a health professional, is ready within 25 minutes.
What is a Remote Lab Test?
A Remote Lab Test (RLT) is an exam that can be performed outside of a clinical analysis lab.
HiLab’s IgM and IgG antibody RLT detects antibodies produced by the body to fight the coronavirus 12 days after exposure. The HiLab test has the differential of offering a double-checked report: by artificial intelligence and by a specialist from our lab.
Result within 25 minutes
TThe result of the HiLab antibody test is fast and safe, making it ideal for testing in clinics, pharmacies, and other places.
Signals the evolution of the disease
This test differentiates IgM and IgG antibodies, produced by the human body at different stages of COVID-19 infection, indicating in which one the person is at.
Suitable for epidemiological tracking
Important in assessing the number of people who had the disease or acquired antibodies against the coronavirus over time.

Antibody Test is simple and fast
REGISTRATION AND COLLECTION
The patient is registered. The blood sample is collected by finger prick, placed in the exam capsule, and inserted into the HiLab device.
SUBMISSION TO THE LAB
The sample is scanned and sent via the internet to our clinical analysis lab.
The examination of the exam undergoes a double-check process by artificial intelligence and by the health professionals of our lab.
The signed report is sent to the patient by email within 25 minutes and is ready to be taken to the doctor.
Differentials of HiLab exams
Differentials for the patient
Differentiates IgM and IgG antibodies
HiLab's antibody test can differentiate between IgM and IgG antibodies. For this reason, it offers a more accurate response to the stage of infection.
Indications and technical specifications of the IgM and IgG antibody test
The HiLab Coronavirus IgM and IgG Remote Lab Test (RLT) is a rapid chromatographic immunoassay for the qualitative detection of IgM and IgG antibodies in blood samples.
The exam is indicated from the 7th day after the onset of symptoms and has the greatest sensitivity when performed 30 days after exposure or 21 days after symptoms onset.
Detected Analytes: IgM and IgG Antibodies for SARS-CoV-2
Sample Type: Whole blood, serum, or plasma
Total exam time: 25 minutes
Results of IgM and IgG antibody test for COVID-19
Non-reactive IgM and IgG
Indicates possible absence of infection. When performed outside the indicated period, there is a possibility of false negative. In this case, the examination should be repeated if clinical suspicion persists.
Reactive IgM and
A reactive IgM result means that the patient is likely to have COVID-19. The fact that the IgM was reactive indicates that the body is producing antibodies at the early stage of infection to fight SARS-CoV-2.
and reagent IgG:
This result indicates probable past infection. However, care with personal and home hygiene must be maintained even after recovery. Remember that SARS-CoV-2 infection can occur more than once.
Reagent IgM and
The reactive IgM and IgG result means that the patient is likely to have COVID-19. The fact that the IgG was reactive indicates that the organism may be producing antibodies at the later stage of infection.
Important: In all cases, the patient must contact a physician to assess the diagnostic approach.
Discover our other solutions for COVID-19
In addition to the antibody test, HiLab also offers other solutions for fast diagnosis of the infection: the Antigen RLT, which detects the nucleocapsid proteins of the virus, and the PCR-LAMP test, which detects the genetic material of the virus.

Frequently Asked Questions
Does the antibody test detect whether the person has had COVID-19?
What are IgM and IgG?
What are the differences between the antigen test and the antibody test?
Should the antibody test be performed to assess the individual's immune response to the vaccine?
Antibody tests are not recommended for this purpose because they do not allow an error-free conclusion about the response to the vaccine, which can occur for some reasons:
- The level of antibodies needed to prevent COVID-19 is not known, so a positive result (reactant) does not necessarily mean that the person is protected.
- The negative (non-reactive) result may reflect the low sensitivity of the test (false negative). This means that people protected by the vaccine can test negative in the exam.
- COVID-19 vaccines target the production of antibodies against the S protein of SARS-CoV-2. This protein is responsible for binding with our cells and the consequent infection. These are the antibodies that would be the protection markers to be investigated. Compared to current COVID-19 tests, these can check both the level of antibodies against protein S and antibodies against the virus nucleocapsid protein (N). Since this information is not always present in the report, this can lead to misinterpretations.
- Even with a positive result (reactant) for antibodies against protein S, it may not be possible to assess whether this immune system response was induced by the vaccine or if it came from a previous infection with the virus.
What to do to reduce the chance of transmission?
According to the World Health Organization, the best way to prevent the transmission of SARS-CoV-2 is by identifying suspected cases as quickly as possible, testing and isolating infected cases. Among the tests indicated for the initial phase of the infection are the antigen test, RT-PCR, and RT-LAMP. It is also important to identify all close contacts of infected people. The prevention measures should also include the use of masks, frequent hand hygiene with soap and water or 70% alcohol, physical distance when possible, respiratory etiquette (cover nose and mouth with your arm when coughing or sneezing), cleaning, and disinfection of the environment. It is also important to avoid agglomerations indoors and ensure good ventilation in any environment.
