Manufacturers must classify their in-vitro (IVD) devices according to the regulatory requirements of different countries where required to ensure patient safety and regulatory compliance. In Australia, IVDs are classified based on a risk-based approach, considering the potential health risks posed by incorrect test results. This classification applies to commercially available in vitro diagnostics (IVDs) and those developed internally.
Understanding IVD Classification
An IVD is any medical device for examining human body specimens, such as reagents, software, or instruments. These devices provide essential insights into physiological or pathological conditions, congenital disorders, therapeutic interventions, or compatibility with potential recipients. General laboratory products not specifically intended as IVDs fall outside this category.
IVDs are divided into four risk-based classes:
- Class 1: Minimal public health or personal risk (e.g., specimen containers)
- Class 2: Low public health or moderate personal risk (e.g., urine test strips)
- Class 3: Moderate public health risk or high personal risk (e.g., tests for infectious diseases)
- Class 4: High public health risk (e.g., blood donor screening tests)
Higher-risk classifications require stricter conformity assessments and post-market monitoring.
Regulatory Framework
Australia’s IVD regulatory framework includes:
- Pre-market assessment: Ensuring devices meet conformity standards before supply.
- Market authorisation: Inclusion in the Australian Register of Therapeutic Goods (ARTG).
- Post-market surveillance for medical devices: Monitoring compliance with ongoing safety and performance requirements.
Combination Devices
For products containing IVD and non-IVD components, classification aligns with the highest-risk item in the system. For example, a procedure pack containing Class 1, Class 3, and Class IIa components would be classified as a Class 3 IVD.
By adhering to these classifications and regulations, manufacturers and healthcare providers can maintain device safety, performance, and compliance throughout the device’s lifecycle.
