BACKGROUND: With the outbreak of SARS-CoV-2, rapid diagnostics are paramount to
contain the current pandemic. The routinely used realtime RT-PCR is sensitive,
specific and able to process large batches of samples. However, turnaround time
is long and in cases where fast obtained results are critical, molecular point of
care tests (POCT) can be an alternative. Here we report on a multicenter
evaluation of the Cepheid Xpert Xpress SARS-CoV-2 point-of-care test. STUDY
DESIGN: The Xpert Xpress SARS-CoV-2 assay was evaluated against the routine
in-house real-time RT-PCR assays in three medical microbiology laboratories in
The Netherlands. A sensitivity and specificity panel was tested consisting of a
dilution series of SARS-CoV-2 and ten samples containing SARS-CoV-2 and a range
of other seasonal respiratory viruses. Additionally, 58 samples of patients
positive for SARS-CoV-2 with different viral loads and 30 tested negative samples
in all three Dutch laboratories using an in-house RT-PCR, were evaluated using
Cepheids Xpert Xpress SARS-CoV-2 cartridges. RESULTS: Xpert Xpress SARS-CoV-2
point of care test showed equal performance compared to routine in-house testing
with a limit of detection (LOD) of 8.26 copies/mL. Other seasonal respiratory
viruses were not detected. In clinical samples Xpert Xpress SARS-CoV-2 reaches an
agreement of 100 % compared to all in-house RT-PCRs CONCLUSION: Cepheids
GeneXpert Xpert Xpress SARS-CoV-2 is a valuable addition for laboratories in
situations where rapid and accurate diagnostics are of the essence.
