Somerset-based Access Bio, Inc., a leader in the development of diagnostic tests for infectious diseases through research, development and manufacturing, announced that the U.S. Food and Drug Administration (FDA) has granted the company Emergency Use Authorization (EUA) for its SARS CoV-2 RT-PCR test.
Manufactured entirely in the United States, the CareStart™ COVID-19 MDx RT-PCR test uses real-time reverse transcription-polymerase chain reaction (RT-PCR) to detect RNA of the COVID-19 nucleocapsid gene (N gene) and RNA-dependent RNA polymerase gene (RdRp gene) in test subjects, resulting in faster results (83 minutes), as well as 100% sensitivity and 100% specificity.
Access Bio has confirmed 100% consistency in positive (PPA) and negative (NPA) groups during clinical evaluations from samples collected by nasopharyngeal swab from symptomatic patients during the 2020 COVID-19 pandemic period. The CareStart™ COVID-19 MDx RT-PCR test is authorized for distribution and use by healthcare professionals and health systems conducting COVID-19 testing. Specimens are then delivered for analysis to laboratories certified under the Clinical Laboratory Improvement Amendments of 1988 (CLIA) who are subject to reporting test results to healthcare providers and relevant public health authorities as appropriate. Analysis does not require a proprietary system and can be run on some of the most common PCR processing solutions, such as Bio-Rad’s CFX96 Dx system and Thermo Fisher Scientific’s Applied Biosystems™ 7500 or 7500 Fast RT-PCR instrument. Additional information surrounding instructions for use with each system can be found at https://carestart.com/.
“The novel coronavirus is showing no sign of slowing in the United States or other parts of the world, making the ability to quickly scale testing and diagnosis a priority,” said Young H. Choi, president and CEO, Access Bio. “Our products are manufactured wholly in the United States, and are used by the world’s largest global health and humanitarian response organizations. We’ve worked to ensure the CareStart’s accuracy and reliability will make it a leading diagnostic testing solution in a market plagued by false methodologies and subpar alternatives.”
The CareStart™ COVID-19 MDx RT-PCR test is designed for use on SARS-CoV-2 nucleic acid that has been extracted, isolated and purified from nasopharyngeal or oropharyngeal swab specimens. The purified nucleic acid is then reverse transcribed into cDNA followed by PCR amplification and detection using an authorized real-time (RT) PCR instrument. The CareStart™ COVID-19 MDx RT-PCR test includes: 4×1 Step RT-PCR Mix, SARS-CoV-2 primer/probe Mix, MS2 Phage Control, External Positive Control, and External Negative Control.
Access Bio’s CareStart™ RT-PCR test is the first in the company’s CareStart line to be granted Emergency Use Authorization by the FDA, with an IgM/IgG antibody kit also currently under evaluation for FDA EUA. Upon authorization, the CareStart™ COVID-19 IgM/IgG Rapid Diagnostic Test will be distributed in partnership with Intrivo Diagnostics, which will act as a resource for qualified buyers — providers & healthcare professionals, payers and patients — to purchase the point-of-care antibody kits.
“The availability of the CareStart™ COVID-19 MDx RT-PCR brings needed COVID-19 viral diagnostic testing to millions of patients across the U.S. and world during the current pandemic,” said Michael Harbour, MD, MPH, Chief Medical Officer, Intrivo Diagnostics. “These high-quality tests are manufactured in the U.S. by Access Bio, a company with a long history of engineering and manufacturing superior quality diagnostic kits for malaria, dengue, typhus and other infectious diseases.”
