Real-Time Fluorescent RT-PCR Kit for Detecting SARS-CoV-2

For Emergency Use Authorization Only | For in vitro diagnostic use | Rx Only

Product Description

On April 24, 2020, the U.S. Food and Drug Administration (FDA) issued an Emergency Use Authorization (EUA) amendment for BGI’s Real-Time Fluorescent RT-PCR Kit for Detecting SARS-CoV-2. The amendment expands the previously issued EUA label to further include the use of automated sample preparation system, additional viral RNA extraction kit and PCR systems for testing a broader range of clinical samples. Specifically, viral RNA extraction can be processed by the kits manufactured by MGI (a subsidiary of BGI Group) or Qiagen. In addition, the highly sensitive SARS-CoV-2 detection test can return results within 4 hours for 192 samples collected from throat (oropharyngeal) swabs, nasopharyngeal swabs, anterior nasal swabs, mid-turbinate nasal swabs, nasal washes, nasal aspirates and bronchoalveolar lavage fluid (BALF) using the MGI automated sample preparation system. Hospitals and reference laboratories can run the test on Roche LightCycler 480 Instrument as well as Applied Biosystems 7500 Fast, 7500 and QuantStudio 5 Real-Time PCR Systems.

Key Components

Performance Characteristics

1. Limit of Detection (LoD): 100 copies/mL (BALF); 150 copies/mL (Throat Swabs)

2. Reactivity/Inclusivity

In silico analysis was performed and the assay was mapped to 284 complete SARS-CoV-2 genomes of human host in GenBank and GISAID databases as of March 10th, 2020. Primer and probes sequences for Real-Time Fluorescent RT-PCR Kit for Detecting SARS-CoV-2 had 100% homology to all SARS-CoV-2 isolates analyzed.

3. Analytical Specificity

Cross-reactivity of the Real-Time Fluorescent RT-PCR Kit for Detecting SARS-CoV-2  was evaluated using both in silico analysis and by wet testing pathogens. No cross-activity was found in the tested pathogens as shown in the table below.

Intended Use and Emergency Use Authorization Information

The Real-Time Fluorescent RT-PCR Kit for Detecting SARS-CoV-2 is an in vitro diagnostic real-time reverse transcription-PCR assay for the qualitative detection of SARS-CoV-2 nucleic acids in throat (oropharyngeal) swabs, nasopharyngeal swabs, anterior nasal swabs, mid-turbinate nasal swabs, nasal washes, nasal aspirates and bronchoalveolar lavage fluid (BALF) from individuals who are suspected of COVID-19 by their healthcare provider. Testing is limited to laboratories certified under the Clinical Laboratory Improvement Amendments of 1988 (CLIA), 42 USC §263a, to perform high complexity tests.

Test results are for the identification of SARS-CoV-2 RNA. The SARS-CoV-2 RNA is generally detectable in respiratory specimens during the acute phase of infection. Positive results are indicative of the presence of SARS-CoV-2 RNA; clinical correlation with patient history and other diagnostic information is necessary to determine patient infection status. Positive results do not rule out bacterial infection or co-infection with other viruses. The agent detected may not be the definite cause of disease. Laboratories within the United States and its territories are required to report all positive results to the appropriate public health authorities.

Negative results do not preclude SARS-CoV-2 infection and should not be used as the sole basis for patient management decisions. Negative results must be combined with clinical observations, patient history, and epidemiological information.

The Real-Time Fluorescent RT-PCR Kit for Detecting SARS-CoV-2 is intended for use by trained clinical laboratory personnel specifically instructed and trained in the techniques of real-time PCR and in vitro diagnostic procedures.  The Real-Time Fluorescent RT-PCR Kit for Detecting SARS-CoV-2 is only for use under the Food and Drug Administration’s Emergency Use Authorization.
