BioGX Ships First Batch of pixl™ Real-Time PCR Platform to US Laboratories

BioGX, a global provider of easy molecular diagnostic solutions since 2007, has announced fulfillment of multiple initial orders for its portable pixl™ real-time PCR platform to customers across the U.S., with immediate plans to scale production to meet market demand.

“We’re very impressed with the response to the launch of our novel ‘pixl’ qPCR platform. Pixl is accelerating validation and adoption of our vast multiplex RUO syndromic panels available in our unique Xfree and Sample-Ready lyophilized formats,” said Shazi Iqbal, Ph.D., BioGX CEO.

The pixl instrument is a compact, 4-channel, 16-well, real-time-PCR instrument that supports rapid turnaround times for batches of up to 16 samples, with integrated results analysis. Previously, in 2022, the US FDA authorized the pixl platform use with the BioGX Xfree COVID-19 Direct RT-PCR EUA test.

BioGX offers an extensive menu of RUO lyophilized multiplex syndromic panels for laboratory validation on the pixl platform, including the extraction-free Direct-Sample-to-Answer assays: Xfree Human Monkeypox (hMPXV), Xfree HSV1/HSV2/VZV and Xfree Treponema pallidum (Syphilis). The Xfree assay format is compatible with most transport/collection media types and can be validated for a wide variety of clinical sample collections.

Jan 2023 Update: BioGX in silico analysis of SARS-CoV-2 Variants of Concern

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 over 930,000 SARS-CoV-2 genome sequences available as of December, 2022. Sequence analysis compared the available Omicron genomes against the SARS-CoV-2 nucleocapsid (N-gene), membrane (M-gene), and RdRp coding region of the ORF1a gene (RdRp) targeted by BioGX products. In-silico analysis and empirical testing of the Omicron variants confirmed gene mutations present as of this analysis, will not affect the performance of the BioGX portfolio of SARS-CoV-2 products.
