Co-Dx™ Logix Smart® SARS-CoV-2 Direct Saliva (DS) test kit

Boost speed and accuracy with real-time PCR testing

The Co-Dx Logix Smart SARS-CoV-2 DS test kit is an in vitro diagnostic test that uses our patented Co-Primers™ technology for the qualitative detection of two genes (gene RdRp and gene E) from the RNA of SARS-CoV-2 (coronavirus that causes COVID-19), using a sample processing technique that eliminates the use of the nucleic acid extraction/purification process.

How it works

The test operates using a single step real-time reverse transcriptase polymerase chain reaction process to to detect SARS-CoV-2 in minimally processed saliva.

Test kit components

The Co-Dx Logix Smart SARS-CoV-2 DS test kit includes the following components.

Ready-to-use Master Mix

Includes the complete mix for convenience and an Internal Positive Control (IPC) - Human RNaseP gene marker

Positive Control

Synthetic control intended to amplify all targets included in the kit to ensure integrity of the entire run

Negative Control

Acts as a negative control to verify Master Mix is free from contamination

Additional information​

The Co-Dx Logix Smart SARS-CoV-2 DS test is a real-time PCR multiplex test intended for the in vitro qualitative detection of nucleic acid from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) targeting the genes RdRp in the polygene Orf1ab region and gene E of the virus genome, in minimally processed saliva samples from individuals suspected of having COVID-19.

The Co-Dx Logix Smart SARS-CoV-2 test 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.
