About TriCore

We believe in engaging all areas of healthcare for results in improved patient outcomes, quality of care, and cost reduction.

TriCore is more than a lab; we are the Southwest’s clinical information company offering expertise in population health management and targeted intervention. We play an active role in New Mexico’s community by offering quality lab outreach, innovative research technologies, and a data repository that enables actionable clinical knowledge.

Our Six Sigma Laboratory provides timely, accurate results, giving physicians more time to spend with their patients, and enabling the best care for New Mexico.

TriCore has emerged as a leader in reference laboratory services, performing a full range of tests – from the routine to the highly esoteric – under the direction of more than 30 pathologists and scientific directors.
