immun19™: OralDNA® Lab’s NEW COVID-19 Neutralizing Antibody Test

In the ever-changing world of COVID, we know that the more knowledge and up-to-date information we have at our fingertips, the more peace of mind and increased security we have. The past year and a half has been a trying time for everyone. Have you wondered if you are protected against the virus? You got the vaccine, but how effective was it? Will a previous infection mount the correct response when you encounter the virus again? I’m sure many, if not all, of us have had these questions go through our minds and can leave us feeling uneasy.

We have good news! OralDNA® Labs can help answer these consuming questions and give you some peace of mind with our NEW Neutralizing Antibody Test- immun19™! The collection process is easy – just a 30 second swish and gargle with sterile saline solution. That’s it! No needles, blood, or pain. Anyone who has been vaccinated, had a confirmed or suspected infection with SARS-CoV-2, or wants to know whether they harbor neutralizing antibodies can be tested. Once the sample is received at our laboratory, you can expect results in just 24-48 hours.

immun19™ is a test to detect for neutralizing antibodies against SARS-CoV-2. Neutralizing antibodies are those that prevent the virus from binding to the cell surface receptor (ACE-2) that is the basis of COVID-19 infections. The test measures not 1, but 3 classes of antibodies involved in immune protection against SARS-CoV-2: IgM, IgA2 and IgG. This is important because IgM and IgA2, are part of the early immune response. That means that they are first on the scene after a recent exposure to SARS-CoV-2. Importantly, IgG, which rises later after infection or following vaccination, is the best measure of durable immunity. So, we will look for the rise and the eventual decline of IgG to tell us when the vaccine is most effective and correspondingly, when a booster shot may be needed.

Salivary diagnostics can increase our knowledge of oral health, immunity, and overall health. We know this is a stressful time in the world and want to help everyone take greater control over information about the status of their own health. Have questions?
