Corona neutralizing antibodies detection

Detection of neutralizing antibodies against SARS-CoV-2 as an indicator for vaccination efficiency

 

Mö-Screen SARS-CoV-2 Neutralizing Antibody (NAb) Test

 (catalogue number: BZL-0240007-10)*

 

 

Lepu Medical COVID-19 Rapid Test Kit

Features:

  • This product is used to qualitatively detect the 2019-nCoV neutralizing antibodies in clinical samples (serum/plasma/whole blood)
  • In this test procedure, the capture reagent for the neutralizing antibodies is immobilized in the test line area of the test. It reacts it with the spike protein antigen coated particles and shows a red color change if the result is positive
  • Lateral flow immunochromatographic assay with procedural control
  • For in vitro diagnostic use (IVD)
  • Sensitivity: 99,9%, Specificity: 99,9%
  • Result in 10 minutes
  • catalogue number:  BZL-0240007-10*

Qualitative detection of SARS-CoV-2 antibodies (IgM and IgG) as an indicator for a previous infection

 

The qualitative detection of SARS-CoV-2 antibodies (IgM and IgG) is mainly intended as an aid to determine a previous natural exposure to the Corona Virus. The tests do not allow differentiation between antibody induced by infection or antibodies induced by vaccination. The detected antibodies can be directed against one viral antigen such as spike protein, nucleocapsid or a mixture of antigens.

 

>> COVID-19 IgG and IgM Rapid Test CE-IVD (Art.-Nr. BZL-17043.T0010)

>> Biovendor Rapid 2019-nCoV IgG/IgM Combo Test CE-IVD (Art.-Nr. BVD-1N38C2)

>> ABM GenomeCov19 IgM/IgG Rapid Test Kit CE-IVD (Art.-Nr. ABM-G630)

>> Abnova COVID-19 Human IgM/IgG Rapid Test (Art.-Nr. ABN-DC0301)

 

For detection of COVID-19 RT-PCR tests remain the gold standard for diagnosis of acute infections with the novel SARS CoV-2 virus.

 


 

Frequently Asked Questions about COVID-19 Antibodies

 

How can the test for neutralizing antibodies help to determin the status of immunity after vaccination?

Not all antibodies are created equal. After Infection with the SARS-CoV-2 the body reacts by producing a multitude of antibodies against different viral proteins (learn more about  SARS-CoV-2 Antibodies). But only neutralizing antibodies bind to proteins on the surface of the corona virus that either sterically prevent the pathogen from binding to the host cell or prevent the conformational change of proteins that is necessary for entry into the host cell. In corona viruses, neutralizing antibodies are often directed against the 2019-nCoV spike protein receptor binding doamain (RBD). Their presence can be interpreted as evidence of immunity to COVID-19 (Khoury et al, Nature Medicine 2021). Antibody tests that do not specifically detect neutralizing antibodies have less predictive value about the status of the immunity, but prove a previous infection with SARS-CoV-2.

 

How long does it take for antibodies against COVID-19 to form?

Antibody Response to COVID-19 Infection

Antibodies against SARS-CoV-2 are formed approximately from the 7th day after infection (IgM and IgA) and remain detectable in the blood for many weeks (IgG). Antibody tests are suitable for the confirmation of an infection in the late stage and for the assessment of the immune status after infection.
At BIOZOL you can obtain various COVID-19 antibody rapid tests for the detection of anti-SARS-CoV-2 IgM and IgG, all of which can be performed directly on site, with a result within a quarter of an hour.
