Brief summary
SARS-CoV-2 Nucleic Acid Detection Kit is an In Vitro Diagnostic (IVD) medical device intended for RNA detection of SARS-CoV-2 in human specimens using multiplex real-time polymerase chain reaction (RT-PCR) technology. The conserved regions of ORF1ab and N genes are used as target sites of the primers and probes according to the indications provided in the Instructions for Use (IFU).
Detailed description
The SARS-CoV-2 Nucleic Acid Detection Kit is an In Vitro Diagnostic (IVD) medical device intended for Qualitative RNA detection of SARS-CoV-2 using multiplex real time RT-PCR technology for professional use. The kit is available in two different formats (48 tests/kit or 200tests/kit), and it can be stored at -20±5ºC away from light for 12 months. This kit includes a PCR Reaction Mix, PCR Enzyme Mix, SARS-CoV-2 PCR Primer/Probe Mix and a negative/positive control. TransGen SARS-CoV-2 Nucleic Acid Detection Kit is intended for in vitro qualitative detection of ORF1ab and N genes from the SARS-CoV-2 virus in nasopharyngeal swab specimens collected from COVID-19 suspected cases, suspected clusters of cases or other individuals who need SARS-CoV-2 infection diagnosis or differentiation diagnosis. The definitions of COVID-19-related groups, such as suspected cases or suspected clusters of cases, are detailed in the Diagnosis and Treatment Protocol for Novel Corona virus Pneumonia, Surveillance Protocol for Novel Corona virus Pneumonia or other COVID-19 documents from the Centers for Disease Control and Prevention (CDC). The TransGen SARS-CoV-2 Nucleic Acid Detection Kit should comply with the requirements of Diagnosis and Treatment Protocol for Novel Corona virus Pneumonia, Protocol for Prevention and Control of COVID-19 and other COVID-19 documents from the CDC. The biosafety requirements should be strictly followed as well. Specimens used for this clinical performance study will be remnants of specimens taken for purposes of standard of care (leftover or archived) through a nasal swab from male and female subjects. Specimens may come from persons suspected of SARS-CoV-2 infection but also from those who need a diagnostic test due to other reasons such as medical intervention, blood donors, or travel for which a negative test is requested.
Interventions
DIAGNOSTIC_TESTLeft-overs
Totally nasal swab leftovers were stored from the biobank of Hospital Puerta del Hierro. The coded specimens were kept at -80°C and analyzed using the SARS-CoV-2 NAD Kit. Previously these specimens were analyzed using the gold-standard RT-PCR.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Sensitivity of the SARS-CoV-2 NAD Kit | Immediately after the procedure | The investigators assessed the sensitivity as the capacity to correctly detect positive specimens of SARS-CoV-2 infection previously confirmed as positive (True Positive, TP) by the gold standard RT-PCR. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Specificity of the SARS-CoV-2 NAD Kit | Immediately after the procedure | The investigators assessed the specificity as the ability to correctly classify previously confirmed as SARS-CoV-2 negative specimens by the gold standard RT-PCR, as negative (True Negative, TN). |
