Performance comparison of 10 SARS-CoV-2 Rapid Antigen Self Tests

We collected 9 different brands of competing products (1) Indicaid, (2) Panbio, (3) Hotgen, (4) AESKU, (5) FlowFlex, (6) BGI YHLO, (7) Jinwofu, (8) Wondfu, (9) Hecin (herein after named a, b, c, d, e ,f, g ,h, i), and performed sensitivity verification, detection performance verification for variant strains, and specificity verification on them.

At the same time, the exact same validation was carried out on the SARS-CoV-2 Rapid Antigen Test produced by Medriva to compare the performance of these SARS-CoV-2 Antigen Rapid test Cassettes. The verification results indicate that in overall highest sensitivity, highest detection of omicron & delta strains, and highest specificity verification indeed is the Medriva COVID-19 Rapid Antigen Test.

Sensitivity verification

Test 10 different brands of SARS-CoV-2 Antigen Rapid test cassettes by diluting the inactivated virus culture solution with extraction buffer. Add 65 mL of sample. During interpretation, record the results and dilution ratios. Until all reagent brands are undetectable, the concentration is high to low.

Below are the results from the tests on the most sensitive SARS-CoV-2 Antigen Rapid test cassette brands, brands “D” and Medriva.

Detection performance verification for variant strains

With extraction buffer, dilution ratios for inactivated virus cultures of Delta and Omicron variant strains are 1:10000, 1:20000, 1:40000, and 1:80000. After testing ten brands of SARS-CoV-2 Antigen Rapid test cassettes with diluted samples, we recorded the results and dilution ratios at the corresponding interpretation time.

According to the results below, the best test brands for the mutant strains Delta and Omicron are brands “a,“d,” and “Medriva”.

Specificity verification

For specificity verification, we collected nine brands of SARS-CoV-2 Antigen Rapid test cassettes, along with the “Medriva” brand SARS-CoV-2 Antigen Rapid test cassette we produced. The next step was to confirm the negative status of 50 subjects by PCR twice in a row. SARS-CoV-2 Antigen Rapid Test cassettes were used to validate nasal swab samples from these subjects

In the results below, brand ‘b,” “c” “e”, “f”, “h”, “i”, and brand ‘Medriva’ were found to have better specificity than brand “b”, “c”, “e”, “f”, and “h”.

Moving On

A Path Forward

The Medriva COVID-19 Rapid Antigen Test is one of the most effective and efficient detection kits of a nucleocapsid protein, an antigen, which forms part of the SARS-CoV-2 virus is now available as a Self Test. Even while vaccines roll out, COVID-19 testing will remain crucial to helping us all return to normal as we begin to engage in everyday life once again.

Now, with Medriva authorized for over the counter for frequent asymptomatic use, we are making testing directly available for fast results, when and where you need it. You can now access our Medriva test in three ways: at your local retailer, order online directly or ask your healthcare professional. This combination will help attack the pandemic on critical fronts – speed, simplicity, affordability, access and reliability.

No more lines, no more wait times, no more barriers and no more inconveniences. Answers are now in your hands.

As countries begin to live with COVID-19, mass rapid testing (MRT) becomes the main tool to control any future outbreaks. Eliminating the virus completely, through stringent lockdown and quarantine measures, and treating it as endemic are often discussed as mutually exclusive strategies. Frequent and widespread adoption of at-home antigen rapid testing could offer the best of both worlds.

Critics of RATs say that PCR is much more sensitive, but this can actually be a liability when it detects a residual amount of RNA during a waning, non-infectious case. Data from a study by the UK COVID-19 Lateral Flow Oversight Team shows that RAT sensitivity for contagious cases, even when asymptomatic, is typically around 97 percent. This means that, with rapid testing, positive individuals can reliably know which few days they need to stay at home, while everyone else testing negative can confidently get on with their lives.

Medriva is a professional in-vitro diagnostics company with aims of contributing to higher life quality by diagnosing illnesses accurately and quickly. Guarding human lives is the most vital component of the healthcare system during this pandemic situation. The most pressing need is to have access to precise diagnostic processes in order to get primary treatment. Because of this, Medriva has invested millions of dollars in R&D to bring new COVID-19 diagnostics kits and tests to the market across Asia, Australia, Europe and North America.

Medriva is built on protection. We strive to achieve patient health. And we’ll get there using innovation, product development, and the most advanced R&D team.
