Description
Defibrinated Blood Soil (BZ538) – ASTM F3208-20 – High-Quality Cleaning Validation Solution by Biochemazone®
Biochemazone’s Defibrinated Blood Soil (BZ538) is a specially formulated artificial test soil designed for simulated-use soiling of medical devices to conduct cleaning validation and verification studies. This product is an essential tool for ensuring thorough and effective cleaning processes for reusable medical devices. The formulation is based on defibrinated blood components, eliminating fibrin to prevent clotting and ensure uniform application and reproducibility.
The BZ538 formulation contains a blend of key biological markers, including hemoglobin, serum proteins, lipids, and electrolytes, closely mimicking contaminants typically found on medical devices after exposure to blood during clinical procedures. Biochemazone’s Defibrinated Blood Soil (BZ538) is a standardized test soil specifically developed to meet the requirements of ASTM F3208-20, the standard guide for validating cleaning processes for reusable medical devices.
This product is engineered to simulate the physicochemical behavior of real blood contamination while offering enhanced consistency and repeatability due to its non-clotting characteristics, making it highly suitable for controlled laboratory validation studies.
Why Biochemazone® Defibrinated Blood Soil is the Best Choice

Biochemazone® Defibrinated Blood Soil ASTM F3208-20 stands out with its unmatched quality, precision, and compliance with FDA, AAMI, ISO, and Health Canada guidelines.
With this test soil, you can effectively simulate blood-based contaminants such as hemoglobin, proteins, and lipids, ensuring your cleaning protocols meet the highest safety and performance standards.
If you are a medical device manufacturer, third-party reprocessor, or independent testing laboratory aiming to meet regulatory guidelines from agencies such as AAMI, FDA, CDC, Health Canada, CEN, and CSA, Biochemazone® Defibrinated Blood Soil ASTM F3208-20 offers an efficient and reliable solution. This advanced formulation is developed through detailed analysis of blood-based contaminants typically found on medical instruments after use, ensuring close replication of real-world conditions. The test soil contains biological materials such as hemoglobin, serum proteins, lipids, and electrolytes, making it ideal for validating reprocessing protocols in line with regulatory standards.
Real-World Simulation
Biochemazone’s Defibrinated Blood Soil ASTM F3208-20 replicates blood-based contaminants commonly found on reusable surgical instruments post-clinical use. The formulation includes hemoglobin (~2.5 mg/mL), serum proteins (~30–35 mg/mL), and lipids, accurately representing contamination levels observed in worst-case clinical scenarios. The absence of fibrin ensures consistent distribution and repeatability, supporting reliable validation of cleaning procedures as outlined by FDA and international regulatory requirements.
Ease of Use
Defibrinated Blood Soil ASTM F3208-20 is pre-formulated and ready to use, simplifying the process of assessing cleaning protocols for medical devices. Its non-clotting nature ensures smooth application and consistent coverage across device surfaces.
Versatile Applications
Defibrinated Blood Soil ASTM F3208-20 can be used across various applications, including:
- Verifying cleaning protocols for reusable medical instruments
- Assessing the effectiveness of reprocessing and decontamination methods
- Testing removal of blood residues and organic contamination
- Training staff in contamination detection and cleaning validation
The test soil can also be modified by adding endotoxins, microorganisms, or other biological agents to simulate post-use conditions more accurately.
Consistency and Stability
Unlike whole blood or fibrin-containing soils that may clot and vary between batches, Biochemazone’s Defibrinated Blood Soil ASTM F3208-20 ensures excellent batch-to-batch consistency. The formulation aligns with AAMI, ASTM, and ISO standards and follows FDA guidance for simulated-use testing. It offers a long shelf life and remains stable under recommended storage conditions.
Comprehensive Testing Solution
Biochemazone’s Defibrinated Blood Soil ASTM F3208-20 can be integrated with additional validation products to ensure a comprehensive evaluation of cleaning performance. This enables manufacturers to meet regulatory expectations by verifying the effective removal of blood-based residues through established protocols.
