REVEALCOVID-19™ Total Antibody Test Sensitivity and Cross-Reactivity Analysis
04 September 2020 - 7:00AM
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. In addition, MedMira received in May 21, 2020
right to sell in all countries accepting CE mark.
