Unknown
The summary mentions "Sherlock® pattern recognition software," which could potentially utilize AI/ML techniques, but the description is too vague to confirm.
No
The device aids in identifying mycobacteria to differentiate species for diagnostic purposes but does not involve direct treatment or therapy for a patient.
Yes
The intended use states that the device is "intended to aid in the identification of M. tuberculosis and differentiation from other mycobacteria species," which is a diagnostic purpose. It helps identify mycobacteria isolated from clinical specimens.
No
The device description explicitly states that the system uses high performance liquid chromatography (HPLC) performed on an Agilent model 1100 HPLC, which is a hardware component. While it includes software, it is not solely software.
Based on the provided text, the MIDI Sherlock® Mycobacteria Identification System is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the system is used to "aid in the identification of M. tuberculosis and differentiation from other mycobacteria species through the analysis of mycolic acids derived from cultured bacterial samples." This analysis is performed on samples taken from a patient (clinical specimens) but analyzed outside the body (in vitro).
- Method: The system uses High Performance Liquid Chromatography (HPLC) and pattern recognition software to analyze mycolic acids from cultured bacterial samples. This is a laboratory-based test performed on biological samples.
- Context: The description mentions that the system is used "along with other identification methods" and "to identify mycobacteria that have been isolated from clinical specimens by traditional culturing techniques." This further reinforces its role as a diagnostic tool used in a laboratory setting to analyze patient samples.
Therefore, the MIDI Sherlock® Mycobacteria Identification System fits the definition of an In Vitro Diagnostic device.

Intended Use / Indications for Use
The MIDI Sherlock® Mycobacteria Identification System is intended to aid in the identification of M. tuberculosis and differentiation from other mycobacteria species through the analysis of mycolic acids derived from cultured bacterial samples, using high performance liquid chromatography (HPLC) performed on the Agilent model 1100 HPLC, along with Sherlock® pattern recognition software.
The system is used, along with other identification methods, to identify mycobacteria that have been isolated from clinical specimens by traditional culturing techniques. Following observation of growth on the solid medium, identification of the mycobacterial isolate is done with the MIDI Sherlock® Mycobacteria Identification System device. Results should be interpreted in conjunction with other laboratory observations and procedures.

§ 866.3370
Mycobacterium tuberculosis immunofluorescent reagents.(a)
Identification. Mycobacterium tuberculosis immunofluorescent reagents are devices that consist of antisera conjugated with a fluorescent dye used to identifyMycobacterium tuberculosis directly from clinical specimens. The identification aids in the diagnosis of tuberculosis and provides epidemiological information on this disease.Mycobacterium tuberculosis is the common causative organism in human tuberculosis, a chronic infectious disease characterized by formation of tubercles (small rounded nodules) and tissue necrosis (destruction), usually occurring in the lung.(b)
Classification. Class I (general controls).

Trade/Device Name: MIDI Sherlock® Mycobacteria Identification System Regulation Number: 21 CFR 866.3370 Regulation Name: Mycobacterium Tuberculosis Immunofluorescent Reagents Regulatory Class: Class I Product Code: NJO Dated: August 19, 2002 Received: August 19, 2002
Dear Mr. Stimson:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug. and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices. good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
