What is Hemocompatibility Testing?
Hemocompatibility Testing is a critical assessment to evaluate the interaction between medical devices and blood, ensuring safety and biocompatibility for products intended for blood-contacting applications. This test measures key parameters such as hemolysis, thrombogenicity, and complement activation, in compliance with ISO 10993-4 standards.
Hemocompatibility Testing is a vital element of the overall biocompatibility assessment for blood‑contacting devices and is often conducted together with Pyrogenicity Testing and Acute Systemic Toxicity Testing to provide comprehensive safety data.
Scope and Rationale
ISO 10993-4 provides a risk-based framework to evaluate the potential blood interactions of medical devices. This includes contact with circulating blood, blood components, or bone marrow, whether via intravascular, extracorporeal, or implantable applications. The testing strategy aligns with the overall biological risk management process outlined in ISO 10993-1.
Key Hemocompatibility Endpoints
The standard outlines five primary categories of blood interaction to be assessed, each representing a distinct mechanism of toxicity:
- Hemolysis – The rupture of erythrocytes leading to the release of hemoglobin. Assessed using direct and indirect contact assays in vitro (e.g., ASTM F756).
- Coagulation (Clotting) – Evaluation of thrombogenicity, including partial thromboplastin time (PTT), prothrombin time (PT), and platelet activation/aggregation.
- Platelet response – Platelet adhesion, activation, and aggregation analysis, which can be done via flow cytometry or microscopy-based methods.
- Complement activation – Measurement of complement split products (e.g., C3a, SC5b-9) through ELISA techniques.
- Leukocyte activation – Determined through markers such as CD11b or cytokine release (e.g., IL-6, TNF-α), providing insights into immunoinflammatory potential.
Selection of Tests
Test selection is application-specific and considers:
- Type and duration of blood contact (e.g., transient vs. long-term),
- Intended use of the device (e.g., stents, dialysis membranes, catheters),
- Physical and chemical nature of the material,
- Device design and manufacturing process.
Risk assessment must justify omission or inclusion of any test category. In vitro methods are preferred where scientifically valid, and animal testing is reserved for endpoints not yet reliably modeled in vitro.
Methodological Considerations
- Controls: Both negative (inert) and positive (known reactive) material controls are required.
- Physiological relevance: All tests should aim to mimic in vivo conditions as closely as possible—this includes appropriate shear stress, temperature, pH, and anticoagulants.
- Validation and standardization: Assays must be validated per GLP or ISO 17025 where applicable, and adhere to referenced standards (e.g., ASTM, CLSI).
Integration with Risk Management
Hemocompatibility testing is not a stand-alone evaluation but part of a systematic biological risk assessment. Data derived from these tests should feed into the biological evaluation report (BER) and clinical risk-benefit analysis. Findings must be interpreted alongside other toxicological and material characterization data per ISO 10993-18 and -17.
