BioGX COVID-19 Tests Detect Omicron SARS-CoV-2 Variant

Xfree™ COVID-19 Direct RT-PCR Test

BIRMINGHAM, Ala.–(BUSINESS WIRE)–BioGX, a global provider of molecular diagnostic solutions, announced that the Omicron (B.1.1.529), the latest emerging SARS-CoV-2 variant of concern, will be detected by the portfolio of BioGX SARS-CoV-2 products that target the nucleocapsid (N-gene) and envelope (E-gene) for detection of the virus.

BioGX’s SARS-CoV-2 surveillance program includes exhaustive in-silico analysis and experimental testing by BioGX scientists using RNA sequences containing the mutations present within the emerging SARS-CoV-2 variants. The analysis conducted by BioGX confirmed the BioGX portfolio of COVID-19 tests maintain detection coverage for all variants of interest and variants of concern, including the new Omicron variant.

BioGX offers a portfolio of COVID-19 RT-PCR tests for a variety of real-time PCR platforms, including BD MAX™ System, Applied Biosystems™ 7500 Fast Dx, Applied Biosystems™ QuantStudio™ 5, Bio-Rad CFX96 Touch™ and Bio-Rad CFX384 Touch™. Details of each test are available at Within the BioGX portfolio, the Xfree COVID-19 Direct RT-PCR is the most popular test because of its ease-of-use and flexibility for high throughput applications. To perform the RT-PCR testing, the user simply rehydrates the lyophilized Xfree reagent with molecular grade water, adds the patient sample, and runs the test on a validated real-time PCR instrument. Xfree COVID-19 is the only lyophilized, direct sample addition, extraction-free, RT-PCR test to receive FDA emergency use authorization for a variety of widely available real-time PCR instruments and specimen types. Additionally, the test is authorized to run with extracted samples, offering options for the laboratory to adapt the test for any laboratory workflow.

BioGX Omicron Variant Update

On November 26, 2021 and November 30, 2021, the WHO and the United States government SARS-CoV-2 Interagency Group (SIG), respectively, designated Omicron (SARS-CoV-2 variant B.1.1.529) as the newest variant of concern. On December 1, 2021 the first confirmed US case of Omicron coronavirus variant was detected in California. 


BioGX continuously monitors the evolution of COVID-19 variants to ensure our market leading SARS-CoV-2 RT-PCR tests will continue to detect emerging variants without impacting performance. 


BioGX has completed in-silico analysis of the 219 Omicron genome sequences available as of November 30, 2021. Sequence analysis compared the available Omicron genomes against the SARS-CoV-2 nucleocapsid (N-gene) and envelope (E-gene) , targeted by BioGX products. In-silico analysis and empirical testing of the Omicron variant confirmed the gene mutations will not affect the performance of the BioGX portfolio of SARS-CoV-2 products.
