Diagnostics company, producer of “molecular systems and tests for organisms and genetic-based diseases” .
San Francisco Bay Area
Data/Evidence of Effectiveness:
Health provider fact sheet states that while the test has been designed to reduce likelihood of false positive results, both false positive and false negative results are possible. Consideration of COVID-19 exposure and associated symptoms are recommended as secondary considerations to the test result . Includes Sample Processing Control and Probe Check Control, both of which must produce expected results for test to be considered valid . Recommends use of external positive and negative controls, or other authorized controls (ex: SeraCare AccuPlex™ Reference Material Kit, catalog number 0505-0126) [2, 5]. Reported 100% (83.9% – 100%) sensitivity (at 2x limit of detection) and 100% (88.7% – 100%) specificity .
Complimentary Products Needed to Perform Test:
“Xpert Xpress SARS-CoV-2 Cartridges with Integrated Reaction Tubes, disposable transfer pipettes, CD (containing assay definition file), Sample Processing Control (SPC), Probe Check Control (PCC) . Additonal materails not included in kit (GeneXpert Dx, GeneXpert Infinity, or GeneXpert Xpress Systems) outlined in Instructions for Use (IFU) .”
Current Status / Clinical Development Stage / Expected Milestones:
Not FDA cleared/approved; FDA approved to meet EUA criteria . Under EUA, cGMP requirements have been waived ; for in vitro diagnosis of SARS-CoV-2 infection .
250 copies/mL

No. Tests Per Day:
4 tests/run x 1 run/0.5hours x 24 hours/day=192 samples/day (assuming POC 4-sample machine) 80 tests/run x 1 run/0.5 hours x 24 hours/day = 3840 tests/day
Time to Result:
Requires less than one minute of hands-on sample preparation, positive test results “as soon as 30 minutes.” . Devices available for simultaneous testing of 1, 2, 4, 16, 48, or 80 samples .
Test Sample Type:
nasopharyngeal swab, nasal wash/aspirate when using GeneXpert Dx or GeneXpert Infinity Systems, or nasopharyngeal swabs only when using GeneXpert Xpress System .
detects presence of RNA originating from SARS-CoV-2 in samples taken from upper respiratory system 
automated qualitative viral RNA test, RT-PCR based [2, 5]
Xpert Xpress SARS-CoV-2 test 
Clinical Application & Need:
A positive result indicates the patient is actively infected with the virus, and assumed to be contagious
