The description explicitly states "manual reading procedures" and makes no mention of automated analysis, image processing, or AI/ML terms.
No
This device is for in vitro determination of antimicrobial susceptibility of bacteria to determine the minimum inhibitory concentration (MIC) and does not directly treat or diagnose a disease in a living organism.
Yes
The device is intended for "in vitro determination of antimicrobial susceptibility of bacteria," which is a diagnostic purpose to understand how bacteria react to antimicrobial agents.
No
The device description explicitly states it consists of "specialized paper impregnated with a pre-defined concentration gradient of an antimicrobial agent," which is a physical component, not software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The "Intended Use / Indications for Use" section explicitly states that the device is "intended for the in vitro determination of antimicrobial susceptibility of bacteria." "In vitro" means "in glass" or "outside the body," which is a key characteristic of IVDs.
- Purpose: The device is used to determine the minimum inhibitory concentration (MIC) of an antimicrobial agent against bacteria. This is a diagnostic test performed on a sample (bacteria) outside of the patient's body to help guide treatment decisions.
- Device Description: The description of the device as a "specialized paper impregnated with a pre-defined concentration gradient of an antimicrobial agent" used for testing on "agar media" further supports its use in a laboratory setting for in vitro testing.
The information provided clearly aligns with the definition of an In Vitro Diagnostic device.

Intended Use / Indications for Use
The Liofilchem® MTST™ (MIC Test Strip) Eravacycline 0.002-32 µg/mL is a quantitative method intended for the in vitro determination of antimicrobial susceptibility of bacteria. MTST™ consists of specialized paper impregnated with a pre-defined concentration gradient of an antimicrobial agent, which is used to determine the minimum inhibitory concentration (MIC) in µg/mL of antimicrobial agents against bacteria as tested on agar media using overnight incubation and manual reading procedures.
The MTST™ Eravacycline at concentrations of 0.002 - 32 µg/mL should be interpreted at 16-20 hours of incubation.
MTST™ Eravacycline can be used to determine the MIC of eravacycline against the following bacteria.
Eravacycline has been shown to be active both clinically and in vitro against these bacterial species according to the FDA drug approved label:
Gram-positive bacteria
Enterococcus faecalis
Enterococcus faecium
Staphylococcus aureus
Gram-negative bacteria
Citrobacter freundii
Enterobacter cloacae
Escherichia coli
Klebsiella oxytoca
Klebsiella pneumoniae
Eravacycline has been shown to be active in vitro only against the non-fastidious bacteria listed below according to the FDA drug approved label:
Citrobacter koseri
Klebsiella (Enterobacter) aerogenes

Dear Ms. Koeth:
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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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
1
801 and Part 809); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/CombinationProducts/GuidanceRegulatoryInformation/ucm597488.htm); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4. Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm.
For comprehensive regulatory information about mediation-emitting products, including information about labeling regulations, please see Device Advice (https://www.fda.gov/MedicalDevices/DeviceRegulationandGuidance/) and CDRH Learn (http://www.fda.gov/Training/CDRHLearn). Additionally, you may contact the Division of Industry and Consumer Education (DICE) to ask a question about a specific regulatory topic. See the DICE website (http://www.fda.gov/DICE) for more information or contact DICE by email (DICE@fda.hhs.gov) or phone (1-800-638-2041 or 301-796-7100).
