COVID-19 Test Manufacturer Confirms Test Detects Variants

T2 Biosystems, Inc. has announced that its T2SARS-CoV-2™ Panel—a molecular diagnostic test that detects SARS-CoV-2, the virus responsible for COVID-19 infections—is capable of detecting the multiple variants of the SARS-CoV-2 virus most recently identified in the United Kingdom, South Africa, and the United States.

Both the variants identified in the United Kingdom (B.1.1.7) and South Africa (B.1.351) contain multiple mutations, most reflected in the S gene, which encodes the spike protein. To confirm that the T2SARS-CoV-2 Panel would detect these variants and other potential mutations of SARS-CoV-2 viruses, an in silico analysis was performed using genome sequences available in the National Center for Biotechnology Information (NCBI) nucleotide database and GISAID database.

Over 42,000 genome sequences for SARS-CoV-2 were evaluated for alignment with primer and probe sequences from T2SARS-CoV-2 Panel. This analysis demonstrated that the T2SARS-CoV-2 Panel should detect 99.99% of all SARS-CoV-2 viruses based on sequence alignments. A specific analysis of sequences for B.1.1.7 and B.1.351 variants confirmed that the T2SARS-CoV-2 Panel should be able to detect these variants.

The T2SARS-CoV-2 Panel provides results in under two hours utilizing an upper respiratory swab sample. The test runs on the Company’s FDA-cleared and fully-automated T2Dx® Instrument, capable of performing seven tests simultaneously and up to sixty samples per day.
