Genica SARS-CoV-2 TEST SYSTEMS
COVID-19 tests

SARS-CoV-2 TEST SYSTEMS

GENICA offers the full range of test systems for the diagnosis of COVID-19 - from several RT-PCR tests and one antigen test for the diagnosis of current infection to serological tests for differentiated detection of antibodies of different immunoglobulin classes (IgA, IgM, IgG) against various SARS-CoV-2 antigens.

Early detection of SARS-CoV-2 is vital to provide the best possible care for patients and contact persons. This can also prevent the spread of this highly contagious virus. Suitable methods for diagnosing current SARS-CoV-2 infections are the detection of viral RNA by RT-PCR analysis or of viral protein by antigen test.  Defining the antibodies makes it possible to confirm SARS-CoV-2 infection and monitor the duration of immunity in these patients.

All tests are CE marked, which guarantees their high quality. In addition, SARS-CoV-2 RT-PCR and anti-SARS-CoV-2 ELISA (IgG) tests have been approved for use in authorized laboratories by the US Food and Drug Administration (FDA). GENICA is INSTAND E.V. certified for SARS-CoV-2 detection. The certificate guaranties international quality of laboratory diagnostics.

COVID-19 PCR

The RT-PCR test for COVID-19 is the global standard for diagnosing coronavirus. This is a molecular genetic test that uses a technique to amplify small, SARS-CoV-2-specific DNA fragments. It can be used to determine whether the test material contains genetic material of the virus, even in small quantities. The test is performed on nasopharyngeal and oropharyngeal sample (nasal and throat sample). 

The PCR test is the earliest diagnostic marker for COVID-19. It detects the pathogen in subclinical or asymptomatic forms, even before the virus carrier is able to transmit the infection to others. By extracting the carrier of genetic information (RNA) of the virus and subsequent detection by RT-PCR of several genes, unique and specific for SARS-CoV-2, GENICA Lab delivers results of a PCR test using the highest-class laboratory analysis. GENICA’s RT-PCR test for SARS-CoV-2 meets the high analytical criteria for а genetic laboratory. It detects highly sensitive unique genes, specific only for this virus, guaranteeing the accuracy and precision of the results.

GENICA holds INSTAND E.V. certificate for international quality of laboratory diagnostics for SARS-CoV-2.

COVID-19 Antigen Test

COVID-19 antigen assays look for the antigen in the virus envelope protein. These tests are faster than PCR diagnostics but have lower sensitivity and specificity than the PCR test, because they do not multiply the in-vitro viral antigen (as in the PCR method) but detect the actual viral amount in the sample. Due to the lack of viral replication the rapid antigen test is applicable to patients with a high viral load. These tests are a good screening choice for patients with symptoms. The best time for testing is about a week after possible risky contact with a positive patient or during the first week of clinical symptoms. A negative result does not rule out the possibility of COVID-19 infection and should be interpreted in conjunction with the clinical picture, patient history, and epidemiological information. In case of clinical and epidemiological data, regardless of the negative result of the rapid antigen test, PCR must be performed.

Quantitative Tests for SARS-CoV-2 Antibodies

Neutralizing COVID-19 Antibodies

The US company GeneScript®'s cPassTM is a test to detect virus-neutralizing SARS-CoV-2 antibodies, the only one approved by the US Food and Drug Administration (FDA) and the European CE-IVD regulatory authorities for in vitro diagnostics. This test detects the presence and amount of certain antibodies associated with blocking the virus's ability to infect human cells. Therefore the test demonstrates immunity and real seroprotection against infection with the virus that causes COVID-19. All other available tests denote only the detection of antibodies as a concomitant serological marker for a past infection or as an adjunct diagnosis for COVID-19. Neutralizing bodies are formed in the body from 14 to 45 days after infection, depending on the individual immunological response of each organism. Therefore, the test is not recommended to be applied earlier than 2 weeks after confirmed PCR infection or symptoms manifested. The accuracy of the test to detect neutralizing antibodies is 99.6%.

The cPassTM GeneScript® test for anti-SARS-CoV-2 VNT (virus neutralizing antibody) can show whether a person has built up protection against the infection after recovering from it or after being vaccinated.

A positive result from the cPassTM test conveys the presence of over 30% of virus neutralizing antibodies and such result is observed in a large proportion of recovered and vaccinated individuals. The positive result is related to the efficacy of the immunity acquired from COVID-19 after vaccination or infection, and is perceived as a marker for protection against reinfection. Virus neutralizing antibody quantities shows decreasing trend over time, which is individual to each patient.

A negative result (value below 30%) indicates the absence of these antibodies after recovery from COVID-19, or that they are in very low concentrations. Thus the patient is likely to be infected. A negative result can be a very important indicator for timely vaccination.

Diagnostic Range: Spike protein - RBD domain

Diagnostic Method: ELISA IgG

Research Material: Venous blood

Results within: For samples taken before 1.00 p.m. - the same day. For samples taken after 1.00 p.m. – before 2.00 p.m. the next business day.

Fee: BGN 45

The test is recommended to:

  • Individuals who have recovered from COVID-19 to evaluate the presence of neutralizing antibodies
  • Potential donors of hyperimmune plasma for therapeutic purposes
  • Vaccinated individuals to evaluate the production of neutralizing anti Spike / RBD IgG antibodies 
  • The general population - in the context of epidemiological studies

COVID-19 PCR Saliva Test

During a respiratory viral infection, SARS-CoV-2 first infects the cells of the oropharynx and nasopharynx, as the newly formed virus particles are released from the infected cells and enter the salivary secretions. In this way, when a person talks, coughs, sneezes, he/she spreads the virus to the surrounding area, infecting the people around him/her. Following the course of viral infection, saliva stands out as one of the preferred materials for the study of COVID-19.

The PCR saliva test has high sensitivity and specificity. It is non-invasive, completely safe and with zero discomfort for the patient.

Saliva is more sensitive than nasopharyngeal swabs for the diagnosis of asymptomatic and mild COVID-19 infection. It is at least as sensitive as the nasopharyngeal swab in severe COVID-19 infection, according to recent studies published in medical journals.

Saliva PCR test results are recognized worldwide.

Diagnostic Range: SARS-CoV-2

Diagnostic Method: RT-PCR

Research Material: Saliva

Results within: 6 hours

Quantitative Tests for SARS-CoV-2 Antibodies

Binding COVID-19 Antibodies

Binding antibodies tests are useful as diagnostic indicators whether an individual has been infected. They do not indicate whether the infection is current or past. The COVID-19 Binding Antibodies Test is NOT used to diagnose active infection or asymptomatic carriers. In case of a positive test for binding SARS-CoV-2 antibodies, a PCR test is performed to rule out active infection. The Binding Antibodies Test can show whether a person has been in contact with the virus. It cannot distinguish the presence of neutralizing antibodies that are associated with established immunity against SARS-CoV-2.

Diagnostic Range: Nucleocapsid protein

Diagnostic Method: ELISA IgG

Research Material: Venous blood

Results within: For samples taken before 1.00 p.m. - the same day. For samples taken after 1.00 p.m. – before 2.00 p.m. the next business day.

Combined PCR Test for Acute Viral Respiratory Infections

ARVI Screen 18®

PCR test for simultaneous detection of 18 pathogens associated with acute respiratory viral infections. It includes testing for the new coronavirus, the two influenza and 15 non-influenza viruses. 

The test detects a number of respiratory viruses associated with influenza and non-influenza respiratory infections, distinguishing them from SARS-CoV-2, that causes COVID-19.
