The cobas® SARS-CoV-2 Qualitative Test provides reliable and high-quality results for the improved management of COVID-19, in individuals suspected of COVID-19 by their healthcare provider. Healthcare professionals can use this test to assess if patients are at risk of developing the disease by this pathogen, which can contribute to severe respiratory distress, complications, and potential death.
cobas® SARS-CoV-2 Qualitative

Features and benefits of the cobas® SARS-CoV-2 Qualitative Test
The cobas®SARS-CoV-2 Qualitative Test is a single-well dual target assay, which includes both specific detection of SARS-CoV-2 and pan-Sarbecovirus detection for the Sarbecovirus subgenus family that includes SARS-CoV-2. The assay has a full-process negative control, positive control and internal control. Two kit sizes accommodating either 192 or 480 test reactions are available.
Claims include:
- Use of nasal and nasopharyngeal swab sample types
- Use of collection and transport media
- cobas PCR Media Dual Swab Kit
- cobas PCR Media Uni Swab Kit
- cobas PCR Media Kit
- Copan Universal Transport Media (UTM-RT)
- BD™ Universal Viral Transport (UVT)
- 0.9% Physiological Saline
