We offer comprehensive cytogenetic test menu including conventional chromosome analysis, molecular cytogenetics such as fluorescence in situ hybridization (FISH) and chromosomal microarray for both constitutional and oncology conditions in the state of Colorado and beyond. There are over 25 laboratory staff members including ASCP-certified cytogenetic or molecular technologists, and genetics counselors, with an average of 16 years of experience. We strive for the highest quality of patient care.

We train the next generation of healthcare providers such as medical students, medical residents and fellows, as well as medical technologists. We are a member of University of Colorado Cancer Center and provide cytogenetic support to basic research and clinical trials.
