About Us

MicroConstants is a GLP-compliant Contract Research Organization (CRO) dedicated to providing premier quality bioanalytical services, IND-enabling drug metabolism (DMPK) assays, immunoassays, bioassays, and pharmacokinetic analysis services to pharmaceutical and biotech companies developing new chemical entities (NCEs) worldwide. We specialize in method development, method validation, and sample analysis of small molecules, proteins, and peptides using LC/MS/MS, HPLC/UV, and ELISA for preclinical and clinical drug development studies. MicroConstants also assembles and distributes customized specimen collection kits for all types of clinical trials conducted throughout the world.

MicroConstants, Inc. was founded in 1998 in San Diego, California by Gilbert Lam, Ph.D., a veteran in pharmaceutical development and a scientist trained in the field of pharmacokinetics. Our San Diego facility has since grown to become one of the largest bioanalytical LC/MS/MS laboratories on the West Coast of the United States, housing 15 LC/MS/MS systems and occupying 34,000 square feet of office and laboratory space.

In 2007, MicroConstants expanded its operations internationally when Dr. Lam co-founded MicroConstants China Inc. in Beijing, China. The second facility was established to meet the growing demand of pharmaceutical development being outsourced to Asia. MicroConstants China adopted MicroConstants' quality systems, has been GLP-compliant since April 2009, and all key personnel participated in extensive cross-Pacific training.

MicroConstants’ laboratories in San Diego and Beijing are both fully compliant with USFDA, OECD, and MHLW Good Laboratory Practice (GLP) guidelines.
