After applying for B-class in vitro diagnostic (IVD) medical device registration with Malaysia's Medical Device Authority (MDA), manufacturers must adhere to several regulations and requirements to ensure compliance throughout the registration process and after obtaining approval. Here are the key regulations and requirements to follow:

1. Adherence to the Medical Device Act 2012

• Legal Compliance: Ensure ongoing compliance with the Medical Device Act 2012 and its associated regulations. This includes obligations related to device safety, efficacy, quality, and reporting of adverse events.

2. Technical Documentation

• Maintain Updated Technical Files: Keep all technical documentation updated, including device specifications, labeling, risk management reports, and performance evaluation data. Changes to the device or its intended use may require updates to these documents.
• Document Control: Implement a robust document control system to manage revisions and ensure that only current documents are in use.

3. Post-Market Surveillance (PMS)

• Implement PMS Plans: Establish and execute a post-market surveillance plan to monitor the safety and performance of the IVD device once it is on the market. This includes collecting and analyzing data from users and stakeholders.
• Adverse Event Reporting: Have a system in place for reporting adverse events or incidents to MDA within the specified timeframes. Manufacturers are typically required to report any serious adverse events within 15 days of becoming aware of them.

4. Quality Management System (QMS) Maintenance

• Continuous Compliance with ISO 13485: Ensure the QMS remains compliant with ISO 13485 standards. Conduct regular internal audits to assess QMS effectiveness and address any non-conformities.
• Management Reviews: Schedule periodic management reviews of the QMS to evaluate performance and implement improvements as needed.

5. Change Management

• Notify MDA of Significant Changes: If there are significant changes to the device, manufacturing process, labeling, or intended use, notify MDA. Certain changes may require a variation application or new registration.
• Risk Assessment for Changes: Perform a risk assessment for any changes made to the device and document the impact on safety and performance.

6. Registration Renewal

• Monitor Registration Validity: Keep track of the registration's validity period, typically five years for medical devices. Begin the renewal process well in advance to avoid any lapse in registration.
• Documentation for Renewal: Prepare the necessary documentation for renewal, which may include updated technical files and performance data.

7. Training and Education

• Staff Training: Ensure ongoing training for staff involved in manufacturing, quality control, and regulatory compliance to keep them informed of current regulations and best practices.
• User Education: Provide proper training and resources to end-users to ensure they understand how to operate the device correctly and safely.

8. Regulatory Updates Monitoring

• Stay Informed: Regularly monitor updates from MDA regarding changes in regulations, guidelines, and standards that may affect the device or registration requirements.
• Participation in Workshops and Seminars: Attend MDA workshops or training sessions to stay updated on regulatory developments and compliance strategies.

9. Documentation and Record Keeping

• Maintain Comprehensive Records: Keep accurate records of all quality assurance activities, training, complaints, and PMS data. This documentation is essential for audits and regulatory inspections.
• Retention of Records: Ensure that records are retained for the duration specified by MDA, typically a minimum of 5 years after the device has been withdrawn from the market.
