Standard Guide for Blood Cleaning Efficiency of Detergents and Washer-Disinfectors

SIGNIFICANCE AND USE
4.1 Significance—Dried blood represents a significant challenge to cleaning surgical instruments. The water-soluble components of blood are easily rendered insoluble when exposed to heat, chemical solutions, or time at room temperature. The water insoluble component of blood is fibrin built up during coagulation. These proteins bind quite readily to the surfaces of surgical instruments making them difficult to remove even with the aid of chemical cleaning agents. Instruments contaminated with blood residue after reprocessing represent a significant threat for infection to healthcare workers and patients. Healthcare facilities typically employ the use of automated instrument washers. These devices combine mechanical action along with chemical cleaning agents in a staged cleaning cycle designed to thoroughly clean surgical instruments. To function properly, these machines must be performing at targeted mechanical efficiency and deliver the correct chemical cleaning agents at the correct temperature, at the correct dosage for the correct period of time. Manufacturers of automated washers and manufacturers of cleaning detergent need to evaluate the performance of their products utilizing a surrogate for surgical instruments soiled with blood. The results of the performance testing will be used to improve product design and for validation of the performance of their product for various regulatory requirements.  
4.2 Use—The regular, periodic use of the blood soil test is a systemic challenge to the functioning of an automated washer. To properly challenge the cleaning device, the test must be analogous to the dried blood soil, to the stainless steel substrate, and to the physical barriers presented by surgical instruments. These physical barriers include the box lock, or pivot joint of a hinged instrument, the serrated tips, and crevices of surgical instruments. On the test coupon, the components of blood are similar to the state of dried blood on instruments. By utiliz...
SCOPE
1.1 This guide is based on a standardized test soil correlating to coagulated blood suitable for screening tests and the evaluation of the cleaning efficiency of washer-disinfectors used for reprocessing of surgical instruments. This guide strictly deals with cleaning and does not describe any methods that are related to disinfection. See Referenced Documents D5343, D4008, D4265, D2960, and D3050 in Section 2 for additional information.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM F2888-19(Practice)
Standard Practice for Platelet Leukocyte Count—An In-Vitro Measure for Hemocompatibility Assessment of Cardiovascular Materials

SIGNIFICANCE AND USE
4.1 The purpose of this practice is to determine if thrombus formation has occurred by comparing platelet and leukocyte counts in the blood exposed to the test material relative to the blood cell counts in the control blood that has not been exposed to the test material. A large number of platelets and leukocytes becoming entrapped/incorporated in thrombi adhering to the material will be reflected by a decrease in their counts in blood. Thrombogenic materials should not be used for cardiovascular medical devices, unless the purpose of the device is to promote thrombosis.
SCOPE
1.1 This practice assists in the evaluation of cardiovascular device materials for their ability to induce thrombus formation. Thrombus formation is assessed by means of a reduction in human platelets and leukocytes when consumed by thrombus after activation on the material surface. This assay may be part of the hemocompatibility evaluation for devices and materials contacting human blood, as in accordance with ANSI/AAMI/ISO 10993–4. See also Test Method F2382.  
1.2 All safety policies and practices shall be observed during the performance of this practice. All human blood and any materials that had contact with human blood shall be bagged in a biohazard bag, properly labeled with the contents, and disposed of by appropriate means.  
1.3 The human blood should be handled at Biosafety Level 2 (BSL-2) as recommended in the Centers for Disease Control/National Institutes of Health publication, Biosafety in Microbiological and Biomedical Laboratories (BMBL). The human blood donor must have tested negative for Hepatitis B (HBV) and Human Immunodeficiency (HIV) viruses. The blood should be treated like any patient blood and handled/manipulated using standard precautions.
Note 1: The results of this in-vitro test may not correspond to actual human response.  
1.4 The values stated in SI (International System of Units) units are to be regarded as standard. No other units of measurement are included in this standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Some specific hazards statements are given in Section 8 on Hazards.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
