reg 38B Performance requirements for coronavirus test devices
(1) The requirements that a coronavirus test device must meet for the purposes of regulation 38A(5) are set out in paragraphs (2) to (6). (2) A coronavirus test device must be able to be put into service in accordance with this Part. (3) A coronavirus test device that is an antigen test must have— (a) a level of sensitivity, using a 95% two-sided confidence interval, that is entirely above 60%; (b) a level of specificity, using a 95% two-sided confidence interval, that is entirely above 93%. (4) A coronavirus test device that is a direct molecular test must have— (a) a level of sensitivity, using a 95% two-sided confidence interval, that is entirely above 70%; (b) a level of specificity, using a 95% two-sided confidence interval, that is entirely above 93%. (5) A coronavirus test device that is an extracted molecular test must have— (a) a level of sensitivity, using a 95% two-sided confidence interval, that is entirely above 93%; (b) a level of specificity, using a 95% two-sided confidence interval, that is entirely above 97%. (6) Where a coronavirus test device is also intended to detect the presence of anything other than a viral antigen or viral ribonucleic acid (RNA) specific to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the requirements in paragraphs (2) to (5) apply only in relation to its performance in detecting the presence of that viral antigen or viral ribonucleic acid (RNA). (7) In this regulation and in regulation 38C— “antigen test” means an in vitro diagnostic medical device for the detection of the presence of a viral antigen specific to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2); “direct molecular test” means an in vitro diagnostic medical device which— is for the detection of the presence of viral ribonucleic acid (RNA) specific to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and does not use a preliminary step of purification and concentration; “extracted molecular test” means an in vitro diagnostic medical device which— is for the detection of the presence of viral ribonucleic acid (RNA) specific to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and uses a preliminary step of purification and concentration; “sensitivity”, in relation to a coronavirus test device, means the proportion of true positives that are correctly identified by the test, calculated using the equation— “specificity”, in relation to a coronavirus test device, means the proportion of true negatives that are correctly identified by the test, calculated using the equation—
