We are ready to answer your questions and provide guidance.



Bioanalytical (Bio-A) laboratory services are the cornerstone to the success of preclinical PK and toxicology studies, providing drug concentration analysis of dose samples, serum, fluids, and tissues. IITRI’s highly experienced team has proven success in bioanalytical method development of even the most difficult drug compounds for quantitation in complex tissues. Our GLP-compliant bioanalytical laboratory is onsite at our single Chicago, IL location for efficient and transport-free coordination of study teams and sample analysis.

We comply with FDA guidelines for bioanalytical method validation and quantitation of your small molecule or biologic in complex tissues and fluids, from preclinical studies like biodistribution to GLP-compliant IND enabling programs. We also support human clinical trial sample analysis for Phase I, II, and III trials.
