Advantage - high specificity of response
- sensitivity to low concentration
- small amount of material
- low cost- high throughput
- can use with complex mixture
- well defined, acceptable method
- endpoints can be used in hazard assessment
- incorporates broader range of mechanism
- comprehensive evaluation of whole endocrine system
- comparative perspective to other endpoints
Disadvantage - may be positive in vitro but not reach target tissue in vivo
- may fail to metabolically activate toxicant
- some assays require ophisticated specialized equipment
- more costly
- time consuming
- uses live animals
- apical whole animal assays not as useful for determining mechanism
