细胞毒性试验用于评估物质对细胞的有害效应。常见方法包括MTT、LDH释放和细胞凋亡检测等，通过测定细胞的存活、膜完整性和细胞死亡等参数来评估毒性。这些试验广泛用于药物筛选、化学品安全评估和环境毒理学研究。细胞毒性试验可为了解物质对生物体的潜在危害提供重要信息，有助于制定安全性标准和保护措施。

Cytotoxicity tests are used to evaluate the harmful effects of substances on cells. Common methods include MTT, LDH release and apoptosis detection, etc. To evaluate toxicity by measuring parameters such as cell survival, membrane integrity and cell death. These tests are widely used in drug screening, chemical safety assessment, and environmental toxicology studies. Cytotoxicity tests can provide important information for understanding the potential harm of substances to organisms and help develop safety standards and protective measures.
