Serology Testing

SARS-CoV-2 Total Ab test

An antibody test, otherwise known as a serology test, can detect if a person has had coronavirus before and has since recovered. It detects antibodies, which are proteins in the blood that fight off infection.

Covid19 Testing

Nona Scientific is now offering Covid19 testing with two options you and your team can choose. First, you can visit our laboratory in Ocala, FL, for a walk-in test (no appointment needed). Or, you can schedule a mobile test unit to visit you at your Place of business.

NO APPOINTMENT NEEDED

Mobile testing*
(Your Location)

Now offering mobile Covid19 testing for corporations, businesses, and practices that need to test a minimum of 20 or more individuals or staff. Complete a request form to schedule a testing date.

PCR nasal swab test: $125

Please select only one.

How to perform a
nasal swab

Dr. Todd Falcone, otolaryngologist and ear, nose and throat surgeon at UConn Health, demonstrates the correct way to perform a nasopharyngeal swab for COVID-19.

*Mobile testing is for groups of 20 or more including restaurants, bars, corporate employee testing, or any business that wants to make sure their staff is Covid19 free. We do not service residential.

DETECTING ANTIBODIES

What is Serology Testing

An antibody test, otherwise known as a serology test, can detect if a person has had coronavirus before and has since recovered. It detects antibodies, which are proteins in the blood that fight off infection. Nona Scientific, now offers SARS-CoV-2 Total Ab test, which is a blood-based assay to identify all the antibodies that are developed by the human body in response to the novel coronavirus SARS-CoV-2. There are more than 120 serological tests available in the U.S. for SARS-CoV-2, which the FDA has allowed under relaxed guidelines but that have been found to have widely varying results. Only nine of them have received emergency use authorization (EUA) from the FDA; two of these are total antibody tests. Nona Scientific is offering total antibody testing as one of our methods of Covid detection. Testing has found that the SARS-CoV-2 Total Ab test Nona Scientific is offering has 98% sensitivity and 99% specificity.

TOTAL TEST

Implemented Technology

Our implemented technology for COVID-19 testing assesses all the antibodies generated by the disease. In particular, it tracks a trio of antibodies: Immunoglobulin G (IgG), Immunoglobulin M (IgM) and Immunoglobulin A (IgA). These are different classes of antibodies that come into play throughout the course of the disease – and tracking all three is expected to offer the most reliable results. The antibodies have been cross-reactivity tested to ensure they do not result from non-CoV-2 coronaviruses, such as those that are associated with common colds. Different classes of antibodies (IgG, IgM, IgA) appear and become more prevalent at different time points post-infection. Having a test that detects all serotypes enables earlier detection post-infection. The immune response typically becomes detectable around Day 7, first with IgM, followed by IgG.

Immunoglobulin G (IgG)

Immunoglobulin G is a type of antibody. Representing approximately 75% of serum antibodies in humans, IgG is the most common type of antibody found in blood circulation. IgG molecules are created and released by plasma B cells. Each IgG has two antigen-binding sites.

Immunoglobulin M (IgM)

Immunoglobulin M is one of several isotypes of antibodies that are produced by vertebrates. IgM is the largest antibody, and it is the first antibody to appear in response to initial exposure to an antigen.

Immunoglobulin A (IgA)

Immunoglobulin A is an antibody that plays a crucial role in the immune function of mucous membranes. The amount of IgA produced in association with mucosal membranes is greater than all other types of antibodies combined. In absolute terms, between three and five grams are secreted into the intestinal lumen each day.

VALIDATION

SAMPLE COLLECTION

qtq80-QMhdRK

Based on almost 700 samples collected before the full-blown COVID-19 outbreak, the SARS-CoV-2 Total Ab test was found to have 99.56% specificity. Sensitivity was determined by testing patients who had tested positive with a PCR analysis of a nasal swab; those patients were evaluated after eight days and the test was found to have 97.5% sensitivity. The

Technology utilized by Nona Scientific for SARS-CoV-2 Total Ab test was also validated in a longitudinal 51-patient study in COVID-19 patients in three Paris hospitals. All the patients were PCR-positive and had COVID-19 clinical symptoms. Out of a subset of 40 patients, 39 of them took more than eight days but less than 42 days after the onset of symptoms to be antibody-positive.
