REVEALCOVID-19™ Total Antibody Test Sensitivity and Cross-Reactivity Analysis

REVEALCOVID-19™ Total Antibody Test Sensitivity and Cross-Reactivity Analysis

HALIFAX, Nova Scotia, Sept. 03, 2020 (GLOBE NEWSWIRE) — Today, MedMira Inc. (MedMira) (TSXV: MIR) reports findings to further emphasize the high sensitivity of REVEALCOVID-19™ Total Antibody Test 7 days post symptom onset as well as highlights the test’s zero cross-reactivity (i.e. no false positive results) with HIV positive samples.  
Sensitivity and Specificity of REVEALCOVID-19™ Total Antibody Test
According to the recent scientific evidence, antibodies to the SARS-CoV-2 virus are generally detected in blood 1-3 weeks post symptom onset. To evaluate the sensitivity and specificity of MedMira’s REVEALCOVID-19™ Total Antibody Test, blood specimens positive and negative for the antibodies to the SARS-CoV-2 virus, the causative agent of COVID-19, were assessed. Positive blood samples were collected from individuals with the confirmed COVID-19 diagnosis, while negative blood specimens were sourced before the COVID-19 pandemic. The following REVEALCOVID-19™ Total Antibody Test sensitivity and specificity values were observed:
Sensitivity:  >7 days after symptom onset – 99.1% (105/106); (95% CI: 94.8%; 99.8%)
* FDA acceptance criteria is currently set at 90%
Specificity:  98.9% (281/284); (95% CI: 96.9%; 99.6%) 
* FDA acceptance criteria is currently set at 95%
To assess whether REVEALCOVID-19™ Total Antibody Test produces false positive results with the HIV positive samples (i.e. evaluate test’s cross-reactivity), 50, out of the aforementioned 284 negative specimens, were collected from patients with confirmed HIV diagnosis. No cross-reactivity has been observed for REVEALCOVID-19™ Total Antibody Test.MedMira’s Role in the Pandemic Crisis and the Future of REVEALCOVID-19™ Total Antibody Test
“Quality and excellent performance of all our products is to be expected. REVEALCOVID-19™ Total Antibody Test has been shown to detect the presence of total antibodies to SARS-CoV-2 just over 7 days post onset of COVID-19 symptoms.” Hermes Chan, CEO of MedMira continues, “High-quality serological antibody testing is not only key in the overall surveillance of the COVID-19 pandemic, but also serves as a crucial tool in the assessment of the vaccine effectiveness. The accelerated process of the vaccine development strongly relies on the availability of serological tests that can help assess the extent of the induced production of antibodies to the SARS-CoV-2 virus.” 
MedMira is under review by the US FDA to obtain FDA Emergency Use Authorization (EUA). However, while awaiting the approval, REVEALCOVID-19™ Total Antibody Test can be distributed in the U.S. according to Section IV.D of the Policy for Coronavirus Disease-2019 Test.
