Section 866.3045 - In vitro diagnostic device for Bacillus spp. detection(a)Identification. An in vitro diagnostic device for Bacillus species (spp.) detection is a prescription device used to detect and differentiate among Bacillus spp. and presumptively identify B. anthracis and other Bacillus spp. from cultured isolates or clinical specimens as an aid in the diagnosis of anthrax and other diseases caused by Bacillus spp. This device may consist of Bacillus spp. antisera conjugated with a fluorescent dye (immunofluorescent reagents) used to presumptively identify bacillus-like organisms in clinical specimens; bacteriophage used for differentiating B. anthracis from other Bacillus spp. based on susceptibility to lysis by the phage; or antigens used to identify antibodies to B. anthracis (anti-toxin and anti-capsular) in serum. Bacillus infections include anthrax (cutaneous, inhalational, or gastrointestinal) caused by B. anthracis, and gastrointestinal disease and non-gastrointestinal infections caused by B.cereus.(b)Classification. Class II (special controls). The special controls are set forth in FDA's special controls guideline document entitled "In Vitro Diagnostic Devices for Bacillus spp. Detection; Class II Special Controls Guideline for Industry and Food and Drug Administration Staff." For availability of the guideline document, see § 866.1(e) .(c)Restriction on Distribution. The distribution of these devices is limited to laboratories that follow public health guidelines that address appropriate biosafety conditions, interpretation of test results, and coordination of findings with public health authorities.(d)Restriction on Use. The use of this device is restricted to prescription use and must comply with the following:(1) The device must be in the possession of:(i)(A) A person, or his agents or employees, regularly and lawfully engaged in the manufacture, transportation, storage, or wholesale or retail distribution of such device; or(B) A practitioner, such as a physician, licensed by law to use or order the use of such device; and(ii) The device must be sold only to or on the prescription or other order of such practitioner for use in the course of his professional practice.(2) The label of the device shall bear the statement "Caution: Federal law restricts this device to sale by or on the order of a ____", the blank to be filled with the word "physician" or with the descriptive designation of any other practitioner licensed by the law of the State in which he practices to use or order the use of the device.(3) Any labeling, as defined in section 201(m) of the Federal Food, Drug, and Cosmetic Act, whether or not it is on or within a package from which the device is to be dispensed, distributed by, or on behalf of the manufacturer, packer, or distributor of the device, that furnishes or purports to furnish information for use of the device contains adequate information for such use, including indications, effects, routes, methods, and frequency and duration of administration and any relevant hazards, contraindications, side effects, and precautions, under which practitioners licensed by law to employ the device can use the device safely and for the purposes for which it is intended, including all purposes for which it is advertised or represented. This information will not be required on so-called reminder-piece labeling which calls attention to the name of the device but does not include indications or other use information.(4) All labeling, except labels and cartons, bearing information for use of the device also bears the date of the issuance or the date of the latest revision of such labeling.84 FR 12088, Apr. 1, 2019
