How Much Does a Cytotoxicity Test Cost

Introduction to cytotoxicity test

Cytotoxicity test is an in vitro testing method that simULates the growth environment of organisms in an isolated state to detect the biological responses induced by medical devices, biomaterials or cheMICals after contacting body tissues.

Cytotoxicity itself refers to a simple cell-killing event caused by cells or chemicals, which does not depend on the specific cell death mechanisms of apoptosis or necrosis. When cells are exposed to toxic substances, they may exhibit a series of responses such as necrosis (uncontrolled cell death), apoptosis (programmed cell death), autophagy, or cessation of growth and division.

In the field of medical devices and biomaterials, cytotoxicity testing plays a vital role. Since these products will ultimately be used in the human body and directly contact human tissues and cells, they are requiRED to possess not only excellent physical and chemical properties but also reliable biocompatibility. As one of the most critical indicators in the biocompatibility evaluation system, cytotoxicity testing is designated as a mandatory item for the biological evaluation of medical devices, thanks to its advantages of simplicity, rapidity, high sensitivity and reduced reliance on laboratory animals.

The degree of cytotoxicity is mainly evaluated by detecting changes in cell membrane permeability. Common testing methods include the MTT assay, CCK-8 assay, LDH release assay, agar diffusion method and direct contact method.

Standards for Cytotoxicity Test

The ISO 10993 series standards constitute the core standard system for the biological evaluation of medical devices, among which iso 10993-5 is specifically dedicated to in vitro cytotoxicity testing. This standard specifies the basic requirements and method selection criteria for in vitro cytotoxicity testing of medical devices, and is widely recognized by international regulatory authorities such as the U.S. FDA and the EU CE certification.
