Cytotoxicity Testing Service

Cytotoxicity studies are laboratory tests conducted to assess the harmful effects of a substance on cultured cells. These studies help determine whether a chemical, drug, or other material can damage cells, inhibit their growth, or cause cell death. Cytotoxicity testing is a key step in the early stages of product development, particularly for pharmaceuticals, cosmetics, medical devices, and environmental chemicals.

These studies are essential for:

• Screening new compounds – to identify toxic effects before animal or human testing.

• Evaluating cell viability – measuring the ability of cells to survive after exposure.

• Detecting cell damage – including membrane disruption or organelle injury.

• Assessing dose-response relationships – to determine the concentration at which a substance becomes harmful.

• Ensuring product safety – especially in cosmetics, where human testing may be limited.

Cytotoxicity assays, such as MTT, LDH release, or Trypan Blue exclusion, provide quick, cost-effective, and ethical methods to predict potential toxicity.
