OSF Healthcare Careers

Laboratory Tech Careers

Contributions by professionals in the clinical laboratory grow ever more valuable as technology advances, knowledge of diseases grows and understanding of the human body improves.

Laboratory technicians might have little or no personal interaction with patients, but their work affects up to 70% of the critical decisions regarding diagnosis, treatment, admission and discharge.

At OSF HealthCare, our lab professionals are valued as true partners in our Mission to serve with the greatest care and love. We offer excellent employee benefits, compensation and a supportive work environment with access to new opportunities.

For the second year in a row, OSF HealthCare has been named one of the best employers in the country – and the No. 1 Illinois-based health care system – for 2019 by Forbes magazine.

Job Types

  • Clinical laboratory scientist
  • Histology technician
  • Lab assistant
  • Medical laboratory technician
  • Non-traditional technologist
  • Phlebotomist


  • Blood bank

  • Blood Bank is responsible for providing blood products for safe transfusions. We have numerous products on hand, including red blood cells, platelets, cryoprecipitate and plasma.

    Blood bank technologists perform compatibility testing and antibody identification along with extended antigen typing. Blood Bank supports our busy Level I Trauma Center and oncology units.

  • Coagulation

  • Coagulation tests measure the ability of blood to clot, as well as how long it takes. They usually are ordered when someone is experiencing abnormal bleeding or bruising.

    Testing can assess the risk of excessive bleeding or the formation of clots (thrombosis) somewhere in the blood vessels.

    By evaluating the levels of individual proteins, cofactors and enzymes necessary for coagulation, we can determine the synthetic markers for several blood disorders.

  • Chemistry

  • Tests run in the chemistry department help determine the concentration of certain chemicals in the body via blood, urine and other bodily fluids.

    Common tests include glucose, blood urea nitrogen (BUN), creatinine, potassium, electrolytes, liver functions, thyroid and hormone levels.

  • Cytology

  • Cytology is a branch of pathology that deals with diagnosing cancer and other diseases through the examination of cellular samples from the body.

    A technologist uses a microscope to examine the individual cells in the sample for cancerous cells, precancerous changes, or evidence of inflammation or infection.

  • Flow cytometry

  • Flow cytometry is an advanced technology that uses a laser to analyze the physical and chemical characteristics of particles in a fluid.

    Cell components are fluorescently labeled and then excited by the laser in order to count and sort the cells. The lab helps to diagnose different blood, tissue and bone-marrow disorders.

  • Hematology

  • Hematology is the branch of medicine concerned with the study, diagnosis, treatment and prevention of diseases related to the blood.

    It involves treating diseases that affect the production of blood and its components, such as blood cells, hemoglobin, blood proteins and the mechanism of coagulation.

    Coagulation (the study of the body’s clotting process) and urinalysis (the study of urine samples) often are other aspects of the hematology department.

  • Histology

  • This form of testing involves examining the structure of cells and how they relate to the tissue or organs they form.

    Cut into thin slices, the cells are placed under a microscope and treated with dyes and chemicals to detect any abnormalities.

    The lab often works quickly to deliver results while the patient is in surgery and is particularly important for the diagnosis of cancers.

  • Microbiology

  • Microbiology examines patient samples and performs a variety of polymerase chain reaction testing for infectious agents. Specimens include, but are not limited to, swabs from wounds, tissue, nasal/throat swabs, urine, stool, sputum and various body fluids.

    A variety of bacteria, fungi, mycobacteria, parasites and viruses may be detected in these patient samples.

    In addition, organism sensitivities are performed by a variety of methods, and the organism identification is performed by MALDI-TOF methodology.

  • Serology

  • Serology tests look for antibodies in the blood, because some infectious agents do not grow well in the lab and the best way to detect their presence is to test the patient’s blood.

    Some diseases detected this way include mononucleosis, syphilis, chicken pox and shingles.

    Autoimmune disorders such as lupus, rheumatoid arthritis and celiac disease also can be detected with serology.

  • Urinalysis

  • Urinalysis testing involves physical, chemical and microscopic results from urine samples.

    The tests performed detect and/or measure several substances in urine, such as bacteria, cells, cellular fragments and byproducts of normal and abnormal metabolism.

    The results from these tests help in the diagnosis and treatment of various conditions, including urinary tract infection, kidney disease, pregnancy and diabetes.
