An Industry-Leading Clinical and Preclinical CRO With a Solid Reputation

MicroConstants is a GLP-compliant clinical and preclinical CRO (Contract Research Organization) focused on performing regulated bioanalysis, drug metabolism, and pharmacokinetic analysis in support of discovery, preclinical, and clinical drug development studies. We provide highly specialized services in method development, validation, and sample analysis for small molecules, macromolecules, biomarkers, and metabolites, using LC/MS/MS, HPLC/UV, immunoassay, multiplex, and qPCR techniques. We also assemble and distribute protocol-specific specimen collection kits to streamline and simplify the PK collection process for single and multi-site clinical trials.

MicroConstants is now BioAgilytix San Diego!

We are pleased to announce that MicroConstants is now known as BioAgilytix San Diego. In 2021, MicroConstants was acquired by BioAgilytix, a leading global contract research organization focused on supporting pharmaceutical and biotech partners in all phases of drug development. With laboratory locations in North Carolina’s Research Triangle Park; Cambridge, Massachusetts; San Diego, California; Melbourne and Brisbane, Australia and Hamburg, Germany, BioAgilytix provides PK, immunogenicity, biomarkers, and cell-based assay services supporting the development and release testing of therapeutics across a number of industries and disease states.

Since 1998, MicroConstants has supported over 290 biotechnology and pharmaceutical companies by providing deep expertise in GLP compliant bioanalytical services. Now as part of the BioAgilytix family, we add our industry-leading services in method development, validation, sample analysis for small and large molecule therapeutics and biomarkers, as well as qPCR techniques to BioAgilytix’s already impressive contract research services.

The newly acquired San Diego facility is one of the largest bioanalytical LC/MS/MS laboratories in the U.S., housing 25 LC/MS/MS systems and occupying 34,000 square feet of office and laboratory space. The San Diego location is now BioAgilytix’s hub on the West Coast. Expect further recruitment of top scientific talent, as well as robust investment in the newest and best technology platforms and modalities to further support your projects.
