Altru's Laboratory is a College of American Pathologists (CAP) accredited, high complexity laboratory. The laboratory serves northeastern North Dakota and northwestern Minnesota, and operates and advises several regional clinic laboratories. We also provide outreach laboratory services to non-Altru health facilities in the region.


The main laboratory is in operation 24 hours a day, 7 days a week, 365 days a year. There are pathologists       on-site with anatomic and clinical pathology board certifications. Laboratory staff includes medical laboratory scientists, medical laboratory technicians, lab assistants, phlebotomists, histotechnologists, and cytotechnologists.

New tests launched in April 2017 by Mayo Medical Laboratories:


ALK on Cytology Specimens, FISH (ID: FALKC)


Useful for detection of rearrangements involving the ALK gene region at 2p23 in patients with non-small cell lung carcinoma who may benefit from treatment with the ALK inhibitor drugs, like Xalkori (Crizotinib), on previously stained routine cytology slides


Broad Range Bacterial PCR and Sequencing (ID: BRBPS)


Useful for detecting and identifying bacteria (including mycobacteria) from normally sterile sources, including synovial fluid; body fluids such as pleural, peritoneal and pericardial fluids, cerebrospinal fluid (CSF); and both fresh and formalin-fixed paraffin-embedded (FFPE) tissues


Kingella kingae, Molecular Detection, PCR, Blood (ID: KKBRP)


Useful for diagnosing Kingella kingae infection


Known Variant Analysis-3+ Variants (ID: KVAR3)


  • Diagnostic or predictive testing for specific conditions when 3 to 5 DNA sequence variants of interest have been previously identified in a family member, and follow-up testing for these specific variants in other family members is desired
  • Carrier screening for individuals at risk for having 3 to 5 DNA sequence variants that were previously identified in a family member
  • Segregation analysis for 3 to 5 familial DNA sequence variants


MatePair, Targeted Rearrangements, Congenital (ID: MTRBL)

  • Second-tier testing when previous cytogenetic testing has detected a constitutional/congenital chromosome abnormality of unknown significance
  • Determining the size, precise breakpoints, gene content, and any unappreciated complexity of abnormalities identified by conventional chromosome studies
  • Providing important diagnostic, prognostic, and therapeutic information critical to proper patient management
