Southwest Labs

Southwest Labs is a privately held U.S. clinical reference laboratory based in Albuquerque, New Mexico. The company provides medical testing and diagnostic services, with a primary commercial focus on clinical toxicology and infectious disease testing for healthcare providers and patients. Its infectious disease offering includes PCR-based syndromic testing, while its toxicology business includes urine and oral fluid drug testing for prescription monitoring, controlled medications, and illicit substances. Southwest Labs positions itself as a locally owned alternative to large national laboratories and also offers provider support infrastructure such as courier services, EMR integrations, and laboratory portals. The business appears to operate as a fully commercial diagnostics services company rather than a therapeutic drug developer.
