The device is a biological indicator that relies on chemical and biological reactions (color change, microbial growth) to indicate sterilization efficacy, not AI/ML.
No
This device is a biological indicator used to monitor the efficacy of a sterilization process, not to treat a disease or condition in a patient.
No
Explanation: The device is a biological indicator used to monitor the efficacy of a sterilization cycle, not to diagnose a medical condition in a patient.
No
The device description clearly outlines a physical biological indicator (SCBI) consisting of a plastic vial, paper carrier with spores, glass ampoule with broth, and a chemical indicator. This is a hardware-based device used to monitor sterilization efficacy.
Based on the provided information, the Anprolene SteriTest is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: An IVD device is defined as a medical device intended for use in vitro for the examination of specimens, including blood, tissue, and urine, derived from the human body, solely or principally for the purpose of providing information concerning a physiological state, state of health, or disease or congenital abnormality.
- Anprolene SteriTest Function: The Anprolene SteriTest is used to monitor the efficacy of a sterilization process for medical devices. It does this by using a biological indicator (bacterial spores) to determine if the sterilization cycle successfully killed the microorganisms.
- No Human Specimen Testing: The device does not examine any specimens derived from the human body. Its function is entirely related to the sterilization process of other medical devices.
Therefore, the Anprolene SteriTest falls under the category of a sterilization process indicator, not an In Vitro Diagnostic device.

Intended Use / Indications for Use
The Anprolene SteriTest consists of a self-contained biological indicator inoculated with viable Bacillus atrophaeus bacterial spores that is placed in a dedicated BI receptacle in the sterilizer. It monitors the efficacy of the 12 hour sterilization cycle at 20-29°C in the Anprolene AN75 Ethylene Oxide Gas Sterilizer. Critical process parameters for the cycle are summarized in Table 1.

Device Description
The Anprolene® SteriTest consists of a single-use self-contained biological indicator (SCBI) placed in a reusable BI receptacle. It is designed for monitoring the efficacy of the 12 hour sterilization cycle at 20-29°C in an Anprolene AN75 Ethylene Oxide Gas Sterilizer.
The SCBI, the EZTest - Gas Biological Indicator, consists of a plastic vial that serves as the culture tube and a cap including a filter material port to allow ethylene oxide to enter the vial. The plastic vial contains Bacillus atrophaeus spores inoculated onto a paper carrier, and a glass ampoule containing modified soybean casein digest broth and phenol red acting as a pH indicator. There is a chemical indicator printed on the unit label of the SCBI to indicate EO exposure.
Following manufacturer's instructions, the operator inserts the SCBI into the reusable BI receptacle on the purge probe of the Anprolene AN75 Ethylene Oxide Gas Sterilizer, and initiates a 12 hour cycle at 20-29°C. After cycle completion, the SCBI is retrieved and activated by crushing the glass ampoule. The chemical indicator on the SCBI changes from blue to a green/brown color depending on the duration of ethylene oxide exposure. The activated SCBI and an unprocessed control are incubated at 30-35℃ for 48 hours, and monitored for any color change and/or turbidity. Evidence of microbial growth by color change from red-orange to yellow and/or turbidity must be interpreted as a failure to meet the conditions necessary for sterilization (failed cycle); no color change or turbidity indicates conditions for sterilization were achieved (passed cycle).

Summary of Performance Studies
The Anprolene SteriTest was validated using applicable tests in FDA 2007 "Guidance for Industry and FDA Staff: Biological Indicator (BI) Premarket Notification [510(k)] Submissions'', and AAMI/ANSI/ISO 11138-1 "Sterilization of health care products – Biological indicators -Part 1: General requirements" (FDA Recognition Number 14-296).
For the EZTest - Gas Biological Indicators, tests include viable spore population assay, resistance characteristics study, carrier and primary packaging materials (growth inhibition) evaluation, holding time assessment, and reduced incubation time validation. The results of all studies met the established acceptance criteria when applicable.
Under identical exposure conditions, the resistance characteristics of the EZTest - Gas Biological Indicators are equivalent when measured in a Biological Indicator Resistometer in the presence or absence of a vacuum.
The Anprolene SteriTest represents a rigorous challenge to the Anprolene AN75 sterilization process. Its resistance characteristics are greater than the same EZTest-Gas Biological Indicator placed in the worst-case locations of the maximum fabric, metal, and plastic loads. The Anprolene SteriTest was partially positive in each half dose cycle, and negative in each full dose cycle, when tested in each worst-case load. The performance of the Anprolene SteriTest in the 12 hour cycle at 20-29°C in an Anprolene AN75 Ethylene Oxide Gas Sterilizer is summarized in Table 5-3.

The predicate AN7408.14 EOGas 4 SteriTest (K151585) is approved for use in the EOGas 4 Ethylene Oxide Gas Sterilization System manufactured by Andersen Sterilizers, Inc.
The predicate device was modified to create the AN7508.14 Anprolene SteriTest, indicated for use in the Anprolene AN75 Ethylene Oxide Gas Sterilization System by Andersen Sterilizers, Inc. The sterilization temperature and time claims of the predicate device have been modified; no modifications were made to the manufacturing method, technology, or intended use.
5.6 Device Description
The Anprolene® SteriTest consists of a single-use self-contained biological indicator (SCBI) placed in a reusable BI receptacle. It is designed for monitoring the efficacy of the 12 hour sterilization cycle at 20-29°C in an Anprolene AN75 Ethylene Oxide Gas Sterilizer.

The SCBI, the EZTest - Gas Biological Indicator, consists of a plastic vial that serves as the culture tube and a cap including a filter material port to allow ethylene oxide to enter the vial. The plastic vial contains Bacillus atrophaeus spores inoculated onto a paper carrier, and a glass ampoule containing modified soybean casein digest broth and phenol red acting as a pH indicator. There is a chemical indicator printed on the unit label of the SCBI to indicate EO exposure.
Following manufacturer's instructions, the operator inserts the SCBI into the reusable BI receptacle on the purge probe of the Anprolene AN75 Ethylene Oxide Gas Sterilizer, and initiates a 12 hour cycle at 20-29°C. After cycle completion, the SCBI is retrieved and activated by crushing the glass ampoule. The chemical indicator on the SCBI changes from blue to a green/brown color depending on the duration of ethylene oxide exposure. The activated SCBI and an unprocessed control are incubated at 30-35℃ for 48 hours, and monitored for any color change and/or turbidity. Evidence of microbial growth by color change from red-orange to yellow and/or turbidity must be interpreted as a failure to meet the conditions necessary for sterilization (failed cycle); no color change or turbidity indicates conditions for sterilization were achieved (passed cycle).
5.7 Indications for Use
The Anprolene SteriTest consists of a self-contained biological indicator inoculated with viable Bacillus atrophaeus bacterial spores that is placed in a dedicated BI receptacle in the sterilizer. It monitors the efficacy of the 12 hour sterilization cycle at 20-29°C in the Anprolene AN75 Ethylene Oxide Gas Sterilizer. Critical process parameters for the cycle are summarized in Table 5-1.

5.8 Device Comparison
The Anprolene SteriTest is substantially equivalent to the predicate device, the EOGas 4 SteriTest: both indicators are intended for the same use, use the same technology, are designed in the same way, and perform substantially equivalently.
The predicate EOGas 4 SteriTest is designed to monitor the efficacy of the 3 hour sterilization cycle at 50°C in the EOGas 4 Ethylene Oxide Gas Sterilizer, and the subject Anprolene SteriTest is designed to monitor the efficacy of the 12 hour sterilization cycle at 20-29°C in the Anprolene AN75 Ethylene Oxide Gas Sterilizer. The difference raises no issues related to safety or effectiveness of the subject device in the sterilization cycle. A comparison between the devices is listed in Table 5-2.
