In-Vitro Toxicology Assays Market to Reach US$24.3 Bn by 2033 | Persistence Market Research
in-vitro toxicology assays market
The in-vitro toxicology assays market is growing steadily, driven by regulatory pressures, technological advancements, and the shift towards non-animal testing.
LONDON, UNITED KINGDOM, February 5, 2026 /EINPresswire.com/ -- The global in-vitro toxicology assays market is projected to grow from US$ 14.8 billion in 2026 to US$ 24.3 billion by 2033, with a CAGR of 5.9%. This growth is driven by the increasing regulatory pressure to reduce animal testing, expanding pharmaceutical and biotechnology pipelines, and a growing demand for safety assessments in chemicals, cosmetics, and medical products.
Rising drug volumes, biologics, and novel chemicals are creating a need for early-stage toxicity screening. In-vitro assays offer a cost-effective, ethical alternative to animal testing, helping identify safety risks before clinical trials. Technological advancements in cell-based assays, automation, and data analytics are further improving assay efficiency and predictive accuracy.
