Detecting the 'Stealth Omicron' Variant: How Flow Health Stays Ahead

March 27, 2023

The emergence of the new "Stealth Omicron" variant in Osaka, Japan has once again reminded us of the importance of having reliable and accurate COVID-19 tests that can detect the mutations in the SARS-CoV-2 virus. A recent study revealed that the "Stealth Omicron" variant is not detected by the CDC-recommended primer-probe sets targeting the N gene, highlighting the importance of continuously monitoring the genome sequence of the virus.

At Flow Health, we recognize the need for testing solutions that can keep up with the evolving nature of the virus. Our highly sensitive PCR test is designed to detect not only the N gene but also the S and ORF1ab genes. By targeting multiple genes, our PCR test significantly reduces the risk of false-negative results even if one gene fails to detect the virus due to changes in the viral genome. This feature increases the accuracy of our test and ensures that health care professionals can diagnose and treat patients with COVID-19 with confidence.

In addition to targeting multiple genes, our PCR test employs reverse transcription techniques that act as a safeguard against false negatives caused by low viral load or contamination issues during sample collection or processing. These techniques ensure that our test results are highly reliable and accurate.

It is worth noting that rapid antigen tests (RAT) using the N gene have been used for COVID-19 diagnosis, but their sensitivity is much lower compared to PCR tests. Moreover, their efficacy against emerging variants such as the 'Stealth Omicron' is limited. This is why PCR tests are considered the gold standard for COVID-19 testing.

The emergence of the 'Stealth Omicron' variant underscores the need for reliable and accurate COVID-19 tests that can keep up with the ever-evolving nature of the virus. At Flow Health, we are committed to providing our customers with the best possible testing solutions by leveraging the latest advancements in diagnostic testing technology. By doing so, we can help healthcare professionals quickly identify and respond to positive test results, leading to better outcomes for patients and communities.
