¹SAMBA results can be interpreted visually and also reported electronically via the tablet. The ORF1ab target is more sensitive than the N target. Detection of either target results in a positive diagnosis.

²NR – eye read not recorded.

³For PHE Cambirgde method Ct <36 is considered positive for SARS-CoV-2. All samples were positive.
