Richmond, California, April 9, 2020.

DiaCarta Inc, a precision molecular diagnostic company in CA, announced Thursday the US FDA granted Emergency Use Authorization for DiaCarta’s proprietary QuantiVirus™ PCR diagnostic (Dx) test specifically detecting three different genes of SARS-CoV-2, the virus causing the COVID-19 pandemic. DiaCarta recently expanded manufacturing capacity to 500,000 tests per week and is planning to expand to even larger (4x) scale manufacturing to meet the increasing demand for PCR tests to monitor COVID-19.

The QuantiVirus™ test detects all currently known strains of SARS-CoV-2 in nasopharyngeal swabs, oropharyngeal swabs and sputum samples. The three viral RNA-encoded genes are the N, Orf1ab and E genes detected by real-time quantitative Reverse Transcriptase PCR assay enabling high sensitivity and specificity with a limit of detection of 100 copies/mL without any detectable cross-reactivity to other human respiratory pathogens.

Customers, including US reference labs and hospitals with high-complexity molecular Dx laboratories can now use QuantiVirus™ kits to detect SARS-CoV-2 within 2 hours following RNA extraction. “We are already supporting laboratories in the US and overseas to meet their increasing testing needs,” said Ram Vairavan PhD, DiaCarta Senior Vice President, “as our Dx reagent kit can be used with commonly available PCR instruments, such as Applied Biosystems 7500 and QuantStudio 5. We have validated this Dx test in our CLIA lab and are serving current needs of global organizations offering SARS-CoV-2 testing to front line providers.” DiaCarta announced earlier that it has received Conformitè Europëenne (CE) Mark for its product.

About DiaCarta Inc.

DiaCarta is a molecular diagnostics company that has developed innovative technologies that transforms patient care by providing effective precision diagnostics using liquid biopsy. Its novel XNA technology provides high level of sensitivity as it binds to the wild-type sequence and enables only the mutant target sequence to get amplified. Using this technology, the company has developed its highly sensitive ColoScape™ early detection Colorectal Cancer test using blood. Powered by its SuperbDNA™ technology that provides high level of detection as it amplifies the signal and requires no RNA/DNA extraction or amplification, the company has developed its revolutionary RadTox™ test that personalizes radiation therapy, mitigates adverse events and enhances patient care. Based in Richmond, California the company is GMP-compliant and offers CLIA certified laboratory services to its customers. www.diacarta.com

DiaCarta Receives CE/IVD for its New COVID 19 Test that Identifies Delta Plus and New Variants

DiaCarta Inc., a precision molecular diagnostics company and leading developer of novel oncology tests using liquid biopsy today announced that its new QuantiVirus™ SARS-CoV-2 Variant Detection Test received the CE/IVD marking and therefore, can now be commercialized within the EU and rest of the world. This new test screens for the SARS-CoV-2 virus and simultaneously identifies and differentiates all the new mutating COVID 19 variants including the Alpha (UK), Beta (S. Africa), Gamma (Brazil), Delta (India), Delta Plus (India), Epsilon (California) and the Kappa (India) variants.

DiaCarta’s Novel XNA Technology Rapidly Detects Raging New SARS-CoV-2 Variants

DiaCarta Inc., a precision molecular diagnostics company and leading developer of novel oncology tests using liquid biopsy today announced the publication of a study entitled “A Rapid SARS-CoV-2 Variant Detection by Molecular-Clamping Based RT-qPCR” in MedRxiV that demonstrates the enhanced sensitivity and specificity using its proprietary XNA based Molecular Clamping Technology that uses innovative synthetic Xenonucleic acid molecular oligomers (XNA) that hybridize with target wild-type DNA sequences, acting as molecular clamps, to enable the accurate amplification of mutant sequences only, using quantitative real-time polymerase chain reactions (qPCR).

DiaCarta Announces Publication in Nature Scientific Reports Demonstrating cfDNA Biomarker Algorithm Predicts Response and Outcome of Chemotherapy

DiaCarta Inc., a precision molecular diagnostics company with proprietary technologies for the development of novel liquid biopsy oncology tests, announced today the publication of a study in Nature Scientific Reports that demonstrates that DiaCarta’s cfDNA biomarker algorithm could function as a prognostic biomarker and efficacy predictor for non-small cell lung cancer (NSCLC) patients.
