The description details a biological indicator and incubator system that relies on a chemical color change to indicate sterilization efficacy. There is no mention of AI or ML in the device description, intended use, or performance studies. The "Smart-Read" and "Smart-Well" names appear to refer to the self-contained nature and incubation well, not intelligent processing.
No
This device is a biological indicator used for monitoring the efficacy of sterilization processes, not for treating
or diagnosing a medical condition in a patient.
No
Explanation: The device, a biological indicator, monitors the efficacy of sterilization processes by detecting microbial growth, which is a quality control measure for equipment, not a diagnostic measure for a patient's health.
No
The device description clearly outlines a physical biological indicator consisting of a self-contained unit with bacterial spores, a glass ampoule, and a plastic vial. It also mentions an incubator (Smart-Well incubator) as part of the process. This indicates a hardware component is essential to the device's function.
Based on the provided text, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- Intended Use: The intended use is to monitor the efficacy of steam sterilization processes. This is a quality control measure for sterilization equipment, not a diagnostic test performed on a biological sample from a patient to diagnose a disease or condition.
- Device Description: The device contains bacterial spores and culture medium to assess if the sterilization process killed the spores. This is a biological indicator for sterilization, not a diagnostic reagent or instrument used to analyze patient samples.
- Lack of Patient Interaction: The device is used in a sterilizer load and incubated. There is no interaction with a patient or analysis of patient-derived material.
- Regulatory Context: The performance characteristics are established in accordance with USP and ANSI/AAMI/ISO standards related to sterilization, not regulations governing IVDs (like those from the FDA for medical devices).
- Predicate Devices: The predicate devices listed are also biological indicators for sterilization, not IVDs.
In summary, the Smart-Read EZTest – Steam self-contained biological indicator is a device used to validate the effectiveness of a sterilization process, which is a quality control function, not an in vitro diagnostic test.

Intended Use / Indications for Use
Smart-Read EZTest – Steam self-contained biological indicators (SCBI) are for monitoring the efficacy of saturated steam sterilization processes. Performance characteristics are established in accordance with USP 31 for the pre-vacuum 121°C steam process. Additional pre-vacuum saturated steam sterilization temperatures are also included in the Certificate of Analysis. Smart-Read EZTest – steam SCBIs are also appropriate for use in saturated steam processes of 132°C, 134°C and 135°C.
The Smart-Read EZTest – steam SCBI is placed into a sterilizer load in a horizontal position in a location that is judged to be the most difficult to sterilize. A sterilization cycle appropriate for the particular type of load is run. Following the sterilization cycle, the operator removes the SCBI from the load and waits approximately 10 minutes until the device has cooled so it can be comfortably handled: The operator then activates the self-contained ampoule by placing it into the activation well in the Smart-Well incubator and gently pulling forward. This action mechanically flexes the side wall of the plastic vial to break the glass ampoule containing the culture medium. The activated Smart-Read EZTest steam SCBI is then placed in an incubator at 60 ± 2°C for 10 hours which provides conditions conducive to growth of any bacterial spores which might have survived the sterilization cycle. Microbial growth of the indicator organisms will produce acid in the microbiological culture medium containing bromcresol purple, thus lowering the pH of the solution and invoking a yellow color change of the media components. If sterilization conditions are met the spores have been killed and the media will remain clear and purple at the conclusion of the 10 hour incubation time.

Device Description
The biological indicator consists of a self-contained unit which includes: bacterial spores inoculated onto a paper carrier, a small glass ampoule containing sterile culture medium and color indicator, and a plastic vial that serves as the culture tube. This unit complies to the performance characteristics described in USP 31 and ANSI/AAMI/ISO 11138-1.
Spores:
Bacterial endospores of Geobacillus stearothermophilus, ATCC 7953 or equivalent, are inoculated onto a 591 Whatman filter paper carrier cut into ¼" x ¾" strips to be placed inside the plastic body of the device. The population of spores on each individual piece of paper will be between 1.0 x 10(x) and 5 x 10(x).
The spore concentration will be labeled as a 10- or 10 concentration.
The population data is based on the heat shock population assay. The heat shock procedure is 95°C to 100°C for 15 minutes as outlined in USP 31.
Culture Tube:
The culture tube is made of a polypropylene. The plastic culture tube is 1.75" in length and 0.34" in OD. The 0.02″ wall allows the culture tube to be flexible so that the culture media glass ampoule can be broken to activate the test.
Culture Medium:
The culture medium, consisting of a formulated soybean casein digest medium containing bromocresol purple, this medium is filled into ampoules of a Type I borosilicate glass, flame sealed and sterilized. The sealed ampoules are placed into the plastic body with the spore paper.
Filter Paper Vent:
The plastic body is closed with a ½" square autoclavable filter paper vent material.
Cap:
A polypropylene plastic cap is used to hold the vent material in place. This cap has three small holes in it to allow steam and air to freely move in and out of the body.
INCUBATION:
Following exposure to the sterilization process the exposed Smart-Read EZTest is incubated at 60 + 2°C for 10 hours. If spores have survived (sterilization failure) the unit will turn yellow due to the growth of the surviving spores.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Study Type: Physical Performance/Reduced Incubation Time Study
Sample Size: Sets of 100 Biological Indicators (BI)
Key Results: Reduced incubation time was established by exposing sets of 100 BIs to a steam process that reduced the spore population to approximately 1 spore per BI. The exposure was acceptable if at least 30 units demonstrated growth and no more than 80 units demonstrated growth. The units were incubated at 60 ± 2°C for 7 days. The reduced incubation time was identified when 97% of the results of the 7 day results were available. This test was performed with four different spore crops and multiple lots of product from each crop. The data indicated that for all partial cycles tested (1 through 12), the percent growth reached 97% or higher by 10 hours of incubation, generally reaching 100% by 10 to 24 hours.

INTENDED USE OF DEVICE: [as required by Section 807.92(a)(5)]
Smart-Read EZTest – Steam self-contained biological indicators (SCBI) are for monitoring the efficacy of pre-vacuum saturated steam sterilization processes. Performance characteristics are established in accordance with USP 31 for the 121°C steam process. Additional pre-vacuum saturated steam sterilization temperatures are also included in the Certificate of Analysis. Smart-Read EZTest – steam SCBIs are also appropriate for use in processes of 132°C, 134°C and 135°C.
The Smart-Read EZTest - steam SCBI is placed into a sterilizer load in a horizontal position in a location that is judged to be the most difficult to sterilize. A sterilization cycle appropriate for the particular type of load is run. Following the sterilization cycle, the operator removes the SCBI from the load and waits approximately 10 minutes until the device has cooled so it can be comfortably handled. The operator then activates the self-contained ampoule by placing it into the activation well in the Smart-Well incubator and gently pulling forward. This action mechanically flexes the side wall of the plastic vial to break the glass ampoule containing the culture medium. The activated Smart-Read EZTest – steam SCBI is then placed in an incubator at 60 ± 2°C for 10 hours which provides conditions conducive to growth of any bacterial spores which might have survived the sterilization cycle. Microbial growth of the indicator organisms will produce acid in the microbiological culture medium containing bromcresol purple, thus lowering the pH of the solution and invoking a yellow color change of the media components. If sterilization conditions are met the spores have been killed and the media will remain clear and purple at the conclusion of the 10 hour incubation time.

The Smart-Read EZTest – steam SCBI is placed into a sterilizer load in a horizontal position in a location that is judged to be the most difficult to sterilize. A sterilization cycle appropriate for the particular type of load is run. Following the sterilization cycle, the operator removes the SCBI from the load and waits approximately 10 minutes until the device has cooled so it can be comfortably handled: The operator then activates the self-contained ampoule by placing it into the activation well in the Smart-Well incubator and gently pulling forward. This action mechanically flexes the side wall of the plastic vial to break the glass ampoule containing the culture medium. The activated Smart-Read EZTest steam SCBI is then placed in an incubator at 60 ± 2°C for 10 hours which provides conditions conducive to growth of any bacterial spores which might have survived the sterilization cycle. Microbial growth of the indicator organisms will produce acid in the microbiological culture medium containing bromcresol purple, thus lowering the pH of the solution and invoking a yellow color change of the media components. If sterilization conditions are met the spores have been killed and the media will remain clear and purple at the conclusion of the 10 hour incubation time.
