At the University of Washington, scientists are focusing on developing and validating biomarkers in readily available tissues, such as blood, urine, and saliva.
Biomarkers, also known as biological markers, are enzymes, DNA changes, and other cellular chemicals that can alter physiological functions under specific conditions. These changes may predict exposure to hazardous chemicals, impaired cellular, organ or gross function, or special susceptibilities to diseases or damage from toxic agents.
