1 M. tuberculosis complex includes the following species: Mycobacterium tuberculosis, M. bovis, M. africanum, M. canetti, M. microti, M. caprae, and M. pinnipedi . The GHTF founding members auditing systems include: the Canadian Medical Devices Conformity Assessment System; Notified Bodies designated by member states of the European Union.; Australian Therapeutics Goods Administration, Office of Manufacturing Quality; and the Japanese Ministry of Health, Labour and Welfare system for Medical Devices and In-vitro Diagnostics.
4 We recommend that the sponsor describe in a pre-submission the number of patients with non-sputum specimens that will be enrolled in the clinical studies. The use of non-sputum specimen types should be supported by analytical studies showing the different matrix has no effect on device performance.
5 Throughout this special controls guidance, the term “processed” or “processing” is used to describe the digestion, decontamination, and centrifugation to pellet of respiratory specimens.
6 These criteria are based on the Sanger di-deoxysequencing method instruments. If you propose other sequencing methods, you should specify the platform and how you will determine acceptable quality.
7 For 200 subjects, 90% (180/200) with 95% two-sided confidence interval: 85.1% to 93.4%
