COVID-19 Antibody Assay Reagents

FOR RESEARCH USE ONLY


Veravas can help advance your research in infectious disease and vaccine efficacy with the ability to perform highly sensitive COVID-19 neutralizing antibody testing in serum and saliva (Swish-N-Spit).

Select from our different SARS-CoV-2 antigen coated beads and available RUO reagents to quantitatively measure IgG, IgM, and IgA immunoglobulins in a single test with high sensitivity and specificity.

Built on the Veravas Platform

  • Increased Specificity: Our proprietary, magnetic nanobead reagent removes interferences and lowers background noise of an assay. 

  • High Sensitivity: VERAVAS® can use multiple antigen epitopes to increase likelihood of detection and performs a novel concentration or enrichment step to increase sensitivity.

  • True Quantitative Measurement: VERAVAS uses proprietary calibration method to measure the concentration of antibodies in serum/plasma (μg/mL) or saliva (ng/mL). Compared to other assay methods that measure a reference unit that is not consistent among assays. 

  • Measure 3 Immunoglobulins: Most assays only look at one or two antibody types. By quantifying IgG, IgM, AND IgA in a single instance or over time can provide new insight to the body’s immune system response to SARS-CoV-2 or other pathogens.

Performance Data - Serum

Sensitivity Compared to Other Serology Tests

Veravas demonstrated higher sensitivity compared against serology tests from Abbott, Beckman, Roche, and Siemens.

Serum to Saliva Sample Type Agreement

Veravas saliva sample performance has near exact concordance with our serum protocol. Veravas offers the best test and sample type.

Performance Data - Saliva

The high specificity and sensitivity of the Veravas COVID-19 Antibody test makes it possible to detect antibodies in a saliva sample with 100% specificity and >95% sensitivity as early as 2 days from symptom onset. (Blood-based tests typically take 14 days to achieve the same sensitivity).

Positive Agreement by Days Post-Symptom Onset

The clinical sensitivity of the Access Genetics, LLC immun19™ COVID-19 Antibody Test was evaluated by testing saline oral rinse samples that were RT-PCR positive by the OraRisk COVID-19 RT-PCR (EUA200464). Positive saline oral rinse samples were prospectively collected from unvaccinated patients who tested positive for SARS-CoV-2 by OraRisk COVID-19 RT-PCR with known days after symptom onset.

Saline Oral Rinse and Saliva Negative Agreement

The clinical specificity of the Access Genetics, LLC immun19™ COVID-19 Antibody Test was evaluated by testing frozen saliva samples collected prior to November 2019 and by testing presumptive negative saline oral rinse samples that were prospectively collected from patients that met the study inclusion criteria.

Clinical Performance 0-7 Days Post-Symptom Onset

The Access Genetics, LLC immun19™ COVID-19 Antibody Test detected neutralizing secretory antibodies against SARS-CoV-2 spike protein RBD and NTD with 96% sensitivity as early as the day of symptom onset. In comparison, the majority of serum-based serology tests do not demonstrate > 95% sensitivity until 15 or more days after PCR positive results.
