COMMERCIAL COVID-19 TEST KIT WITH LOWEST LOD* NOW AUTHORIZED FOR SYMPTOMATIC AND ASYMPTOMATIC TESTING & POOLING

To address growing supply constraints worldwide, PerkinElmer has expanded the production capacity of its extraction and RT-PCR tests at its global facilities and has the capability to ship millions of these solutions to its customers. 

PerkinElmer New Coronavirus Nucleic Acid Detection Kit authorized under FDA EUA for COVID-19 Testing

The PerkinElmer New Coronavirus Nucleic Acid Detection Kit is a real-time RT-PCR test intended for the qualitative detection of nucleic acid from SARS-CoV-2 in human oropharyngeal, nasopharyngeal, and anterior nasal swab samples. This kit may be used to test either symptomatic or asymptomatic individuals. This assay has been shown to exhibit the highest sensitivity for the commercially available kits when tested with the FDA reference panel*. Testing is limited to laboratories certified under the Clinical Laboratory Improvement Amendments of 1988 (CLIA), 42 U.S.C. §263a, to perform high complexity tests, or by similarly qualified non-U.S. laboratories.

As described in the kit insert, PerkinElmer’s RT-PCR assays target two specific genomic regions of SARS-CoV-2: the nucleocapsid (N) gene and ORF1ab. Thus mutations in spike protein, as seen in the B.1.1.7 and B.1.351 lineages, do not impact the safety and effectiveness of PerkinElmer’s assays.

  • Specific: Detection of SARS-CoV-2 ORF1ab and N genes

  • Sensitive: Limit of detection of 7.14 to 27.24 copies/mL

  • Flexible: Authorized for use with symptomatic or asymptomatic individuals and can be used for pooling of up to 5 samples

  • Reliable: Performance verified with case studies from outbreak’s point of origin

  • Automated: Options available to meet a broad range of sample throughput

  • Efficient: Pooling of multiple samples increases throughput and decreases costs

Compatible with Asymptomatic and Symptomatic Pooling 

The PerkinElmer®  New Coronavirus Nucleic Acid Detection kit can be used for sample pooling for either asymptomatic and symptomatic individuals. This test is also for the qualitative detection of nucleic acid from the SARS-CoV-2 virus in pooled specimens containing up to 5 individual specimens on the chemagic™ 360 instrument.

Pooling is desirable because it allows labs to reduce costs and increase throughput, but it requires a sensitive assay. The PerkinElmer®  New Coronavirus Nucleic Acid Detection kit is the most sensitive commercially available SARS-CoV-2 test kit with the lowest limit of detection in the market, according to the FDA’s reference panel comparative data*.

As one of the few kits authorized for asymptomatic testing and pooling, the complete PerkinElmer® SARS-CoV-2 detection workflow delivers the sensitivity needed to test travelers, students, workforce and others.

REVIEW OF PERFORMANCE COMPARISONS OF COVID-19 WORKFLOWS

Why False Negatives Should be Avoided

Sensitive limits of detection (LoD) are of critical importance because each 10-fold increase in the LoD of a COVID-19 viral diagnostic test is expected to increase the false negative rate by 13% (Arnaout, R., 2020). In the recent Nature publication (Mackey, et al., 2020) report, PerkinElmer New Coronavirus Nucleic Acid Detection kit was stated to have the lowest limit of detection (LoD) described in the IFU for FDA EUA authorized tests reported in copies/μL. To date there have been 5.76 million COVID cases detected in the US alone. If all 5.76 million COVID cases were performed with the kits listed in Table 1, many more samples would be reported as false negatives. These false negatives could be avoided by testing with the PerkinElmer New Coronavirus Nucleic Acid Detection Kit, the most sensitive kit commercially available.

False Negatives

FDA’s Performance Comparison of Nucleic Acid-based SARS-CoV-2 Assays

The FDA developed an experiment to precisely compare the performance of the nucleic acid-based SARS-CoV-2 assays which have received EUA authorization and published a comparative performance analysis. This assessment used the FDA SARS-CoV-2 Reference Panel which allowed a consistent determination of the relative sensitivity of these tests and their cross-reactivity with the MERS-CoV virus. As can be seen in Table 2 on the FDA website, the PerkinElmer New Coronavirus Nucleic Acid Detection Kit had the lowest LOD of the commercially available kits tested.

Sensitive & Specific Nucleic Acid-based Detection
of COVID-19 ORF1ab and N Genes

The PerkinElmer New Coronavirus Nucleic Acid Detection kit has a limit of detection 20 copies/mL for the SARS-CoV-2 ORF1ab and N genes. It does not show cross reactivity with common respiratory tract pathogens and blood stream pathogens including:

  • Human coronavirus (229E, OC43)
  • SARS coronavirus (plasmid)
  • MERS coronavirus (plasmid)
  • Adenovirus (3, 2, 31, 37, 51 types)
  • Enterovirus (A, D)
  • Rhinovirus (A, B)
  • Influenza A virus
  • Influenza B virus
