BACTEC® 460TB SIRE Kit
Method of Proportion agar plates
No
The summary describes a standard laboratory susceptibility test kit and system based on comparing growth in drug-containing tubes to a growth control. There is no mention of AI or ML in the device description, intended use, or performance studies.
No
This device is for in-vitro diagnostic use to determine the susceptibility of Mycobacterium tuberculosis to various drugs, not for direct therapeutic intervention.
Yes
Explanation: The "Intended Use / Indications for Use" section explicitly states that the device is a "rapid qualitative procedure for susceptibility testing of Mycobacterium tuberculosis." This testing provides information crucial for diagnosis and treatment decisions.
No
The device description explicitly states it is a "susceptibility test kit" used with the BACTEC® MGIT™ 960 System and involves physical components like tubes, supplements, and drug dilutions. It is a laboratory assay kit, not a software-only device.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states it's a "rapid qualitative procedure for susceptibility testing of Mycobacterium tuberculosis, from culture, to streptomycin (STR), isoniazid (INH), rifampin (RIF) and ethambutol (EMB)." This involves testing a sample (Mycobacterium tuberculosis from culture) in vitro (outside the body) to determine its susceptibility to various drugs.
- Device Description: The description details how the test is performed using a "Mycobacteria Growth Indicator Tube (MGIT™)-7mL" and "BACTEC® MGIT™ 960 SIRE Supplement enrichment" with drug dilutions. This is a laboratory-based test performed on a biological sample.
- Performance Studies: The document describes analytical and clinical studies involving testing M. tuberculosis strains and clinical isolates. These studies are conducted to evaluate the performance of the test in a laboratory setting.
- Predicate Devices: The mention of "Method of Proportion agar plates" and "BACTEC® 460TB SIRE Kit" as predicate devices further confirms its classification as an IVD, as these are also IVD devices used for similar purposes.
All these points align with the definition of an In Vitro Diagnostic device, which is used to examine specimens derived from the human body to provide information for diagnostic purposes. In this case, the information is about the drug susceptibility of Mycobacterium tuberculosis, which is crucial for diagnosing and treating tuberculosis.

Device Description
The BACTEC® MGIT™ 960 SIRE susceptibility test kit is used with the BBL® Mycobacteria Growth Indicator Tube (MGIT™)-7mL on the BACTEC® MGIT™ 960 System. The tube is supplemented with BACTEC® MGIT™ 960 SIRE Supplement enrichment and prepared with the appropriate dilutions of streptomycin, isoniazid, rifampin and ethambutol as the mechanism for performing the susceptibility test. The BACTEC® MGIT™ 960 SIRE test utilizes a four to thirteen day testing protocol. A standardized suspension of Mycobacterium tuberculosis growth, from either solid or broth culture media, is prepared. An appropriate dilution is made of this suspension and 0.5 mL is inoculated into a Growth Control tube (drug-free) and tubes containing streptomycin, isoniazid, rifampin and ethambutol (this is referred to as an AST Set). The test interpretation is based on growth of the Mycobacterium tuberculosis isolate in the Growth Control tube compared to the growth in the drug-containing tubes. At the completion of the susceptibility testing protocol, the instrument reports a susceptible or resistant result for each drug at the concentration(s) being tested.

Summary of Performance Studies
Analytical studies:
Lot Reproducibility: Reproducibility of the BACTEC® MGIT™ 960 SIRE ethambutol susceptibility test was evaluated using twenty-five M. tuberculosis strains (to include five ATCC strains). Each strain was tested ten times at the indicated drug concentration. Overall reproducibility for the BACTEC® MGIT™ 960 ethambutol test at the critical concentration is 100%.
CDC Challenge Panel Testing: The performance of the BACTEC® MGIT™ 960 SIRE ethambutol susceptibility test was evaluated using a panel of thirty challenge strains obtained from the Centers for Disease Control and Prevention (CDC), GA, USA. Observed results were compared to the CDC expected results. The overall agreement of the BACTEC® MGIT™ 960 ethambutol test at the critical concentration with CDC expected results is 100%.
Clinical Evaluation: The BACTEC® MGIT™ 960 SIRE ethambutol susceptibility test was evaluated at five clinical sites composed of regional reference centers and university hospital-based laboratories, including one foreign site.
Reproducibility Testing: The reproducibility of the BACTEC® MGIT™ 960 SIRE ethambutol test was evaluated at all sites using a panel of ten qualified strains. Observed results were compared to the expected results. Overall reproducibility for the BACTEC® MGIT™ 960 ethambutol test at the critical concentration is 97.5%.
CDC Challenge Panel Testing: The performance of the BACTEC® MGIT™ 960 SIRE ethambutol susceptibility test was evaluated using a panel of thirty challenge strains obtained from the Centers for Disease Control and Prevention (CDC), GA, USA. Observed results were compared to the CDC expected results. The overall agreement of the BACTEC® MGIT™ 960 ethambutol test at the critical concentration with CDC expected results is 93.3%.
Clinical Isolate Testing: A total of 106 clinical isolates of M. tuberculosis were tested with the BACTEC® MGIT™ 960 SIRE ethambutol susceptibility test and the MOP susceptibility test. This included testing of both fresh clinical and stock isolates from both liquid and solid culture sources. This generated a total of 223 test results for the ethambutol test at the critical concentration. Category agreement was calculated for isolates from both liquid and solid source cultures tested at EMB 5.0. The agreement for liquid source susceptible strains is 97% and for resistant strains is 85%. The agreement for solid source susceptible strains is 99% and for resistant strains is 80.0%.
All isolates with discordant BACTEC® MGIT™ 960 EMB 5.0 results were tested by MOP at two independent sites. Of the four discordant EMB resistant (R-960, S-MOP) isolates, one had resistant results from both sites and three had susceptible results from both sites. Of the eight discordant EMB susceptible (S-960, R-MOP) isolates, six had susceptible results from both sites and two had resistant results from one site and susceptible results from the other site.
The overall performance data demonstrate that the BACTEC® MGIT™ 960 SIRE ethambutol susceptibility test, used with the BACTEC® MGIT™ 960 System, is substantially equivalent to the Method of Proportion susceptibility test that was in use prior to May 28, 1976.
