Laboratory

Altru's Laboratory provides physicians with concrete data to help determine a patient's diagnosis by testing personal specimens including blood and blood products, bodily fluids and tissue.

Nearly 9,000 specimens are collected from the hospital each month, and approximately 6,300 are collected from other Altru locations. With technology, Altru's lab achieves greater efficiency, prompt resulting and improved patient care. 

The laboratory is open twenty-four hours a day, seven days a week and is staffed with approximately 150 professionals.

Hematology is the counting and differentiation of cell types within the body and body fluids. Hematology tests can help diagnose anemia, leukemia, mononucleosis, and indicate viral or bacterial infection. 

Coagulation is the process that determines how well blood clots. 

Urine specimens may be tested for several chemical components, such as glucose (sugar), cellular (red and white blood cells) or bacteria.  This information is utilized by the physician to check for kidney, liver or urinary tract infections, or even pregnancy.

Chemistry tests are used to check for problems with many organ systems in the body. Prescribed medications are monitored and regulated by testing the drug levels in the blood, and the use of illicit drugs can be determined with these tests by checking the blood or urine. 

Transfusion Services process and provide blood and blood products for patients.  The Dak-Minn Blood Bank, located in Altru Hospital, is our main supplier of blood products.  Altru's Transfusion Services is responsible for ensuring the patients being treated at Altru Health System have an adequate and safe blood supply. 

Microbiology tests determine bacteria, viruses, specific antigens and antibodies for certain diseases in a specimen. The microbiology laboratory tests several antibiotics to help the physician and pharmacist determine the best and least expensive way to treat the patient, and ultimately stop the infection.

In Histology, a pathologist examines and diagnoses the patient, based on the tissue sample. Approximately 13,500 surgical pathology cases are processed annually in our service area.

Cytology is "the study of cells."  A cytotechnologist examines human cell samples and works with a pathologist to arrive at a final diagnosis.
