Standard Operating Procedure for Sterility Testing
SOP Version: 1.0
Purpose:
The purpose of this Standard Operating Procedure (SOP) is to establish guidelines and procedures for sterility testing in the pharmaceutical manufacturing facility. Sterility testing is performed to ensure the absence of viable microorganisms in pharmaceutical products, as per the requirements outlined in relevant pharmacopeias and pharmaceutical references.
Scope:
This SOP applies to all personnel involved in sterility testing activities within the pharmaceutical manufacturing facility. It covers the preparation, handling, incubation, and interpretation of sterility test samples, ensuring accurate and reliable results for assessing the sterility of pharmaceutical products.
Responsibilities:
Quality Assurance (QA):
Ensure compliance with this SOP and related procedures.
Provide oversight and guidance on sterility testing activities.
Review and approve sterility testing results and reports.
Microbiology Laboratory:
Perform sterility testing following approved procedures.
Maintain and calibrate laboratory equipment used for sterility testing.
Document and report sterility testing results accurately.
Manufacturing Personnel:
Provide appropriate samples and documentation for sterility testing.
Adhere to proper aseptic techniques during sample collection and handling.
Report any deviations or incidents related to sterility testing to QA.
Procedure:
Sample Preparation:
a. Verify the integrity and labeling of the sample containers.
b. Ensure that the sample containers are appropriate for sterility testing.
c. Disinfect the exterior of the sample containers before transferring them to the microbiology laboratory.
Sterility Testing Environment:
a. Prepare the sterility testing area, ensuring cleanliness and adherence to aseptic techniques.
b. Disinfect the working surfaces, laminar flow hood, and other equipment used during sterility testing.
Aseptic Transfer of Samples:
a. Perform aseptic transfer of the samples into a sterile container suitable for sterility testing.
b. Label the sterile container with unique identifiers, including the sample identification, date, and time.
Inoculation of Sterility Test Media:
a. Use a sterile syringe or other appropriate method to transfer the sample into the sterility test media.
b. Inoculate the sterility test media aseptically, ensuring proper mixing of the sample and media.
Incubation:
a. Incubate the sterility test media containers in a suitable incubator, as per the approved procedure.
b. Maintain the incubation temperature and duration according to the requirements specified in the pharmacopeia or other applicable references.
Visual Inspection:
a. After the incubation period, visually examine the sterility test media containers for turbidity or growth.
b. Record any observations of microbial growth or turbidity.
Confirmation Testing (if required):
a. If there is any indication of microbial growth or turbidity, perform appropriate confirmation testing as per approved procedures.
b. Follow the specific guidelines outlined in the pharmacopeia or other relevant references for confirmation testing.
Data Evaluation and Reporting:
a. Review and verify all sterility testing data for completeness and accuracy.
b. Compare the results against the acceptance criteria specified in the pharmacopeia or other relevant references.
c. Prepare sterility testing reports, including observations, results, and any necessary follow-up actions.
d. Submit the reports to QA for review and approval.
