Acute Systemic Toxicity Testing

Acute systemic toxicity tests are used to assess the toxicity of chemicals, medical products, and other substances resulting from different types of exposure. These tests are used to determine if substances need protective packaging, warning labels, and environmental release guides, or if protective equipment may be required for handling. Learn about alternatives to animal use for these tests.
