Providence Laboratory Services proudly serves Oregon and Southwest Washington, completing tens of thousands of clinical laboratory tests annually. With eight rapid response hospital laboratories and a comprehensive core laboratory, we are committed to providing the highest quality diagnostic testing for the patients we serve.

Providence Laboratory Services voluntarily participates in extensive accreditation programs, including the College of American Pathologists (CAP), the American Association of Blood Banks (AABB) and The Joint Commission (TJC). All Providence Health & Services laboratories are licensed under Clinical Laboratory Improvement Amendments (CLIA) and accredited through either CAP or TJC, which both hold deemed status under CLIA.

Since most testing is completed locally or regionally, you can expect turn-around times to be better than most other reference laboratory options. If you expect only the best from a laboratory, please visit us for your laboratory needs.

At Providence Laboratory Services, we have the instrumentation and technical staff to quickly and expertly process the diagnostic testing requested. Our services provide comprehensive diagnostic testing to aid in the diagnosis of the patients we serve.

Anatomic pathology

Our pathologists are experienced in a wide array of pathology subspecialties. This allows our team to effectively evaluate patient cases within our department. This allows ordering physicians to make diagnoses that are timely and accurate to select the optimum courses of treatment.


Our full-service cytopathology practice offers screening and diagnostic testing on gynecological, non-gynecological, anal cytology, and fine-needle aspiration/biopsy (FNA/FNB) specimens. We also offer rapid on site assessments of adequacy for FNAs. 

We apply immunohistochemical and molecular diagnostic tests to cytologic specimens. Our laboratory offers a full range (via collaboration with the immunohistochemistry pathology service) of ancillary markers on cytologic specimens in order to make optimal use of cytologic specimen.

Surgical pathology

Surgical subspecialties include bone and soft tissue, breast, genitourinary, gastrointestinal, head and neck, renal and neurological pathologies. Consulting and diagnostic services are also available to surgeons in gross dissection, frozen section techniques, history wave processing and straining. Other services include DNA analysis and molecular diagnostics.

Blood Bank

We perform the testing required to ensure those patient’s that need a blood transfusion are receiving a safe product, including a blood type and check for any unexpected red cell antibodies the patient may have made due to previous red cell exposure. Additionally, testing is performed on maternal patients in order to detect any potential fetal – maternal incompatibilities as well as a variety of tests that will help diagnose various disease states.


With over 400 clinical tests offered in-house within the Providence Oregon network, we provide comprehensive diagnostic workup strategies for rapid diagnosis and treatment of the patients we serve. Each rapid response laboratory is equipped with the diagnostic testing necessary to provide STAT results essential to emergency care of patients.

Billing/Revenue Cycle Test Authorization / Test Ordering

The clinical laboratory shall examine specimens only at the written or electronic request of a physician, dentist, or other person legally authorized (hereto collectively referred to as clinician) to use the findings of the laboratory examinations.

Claims for reimbursement shall only be submitted for tests that are appropriately ordered and performed.

Lab Interface

The Lab Resolution Team manages connectivity via direct HL7 interface between Providence’s Epic HIS and your clinic’s EMR or Lab Information System (LIS). The team provides project management services throughout the implementation process, with ongoing support and troubleshooting to ensure prompt issue resolution.

Patient results may also be accessed via EpicCare Link or Health Information Exchange (HIE). Please reach out to your Providence Account Executive to learn more about these options.


Referral Laboratory CLIA Certification Qualifying Criteria For all referral testing, the referring laboratory is responsible for the selection of quality criteria and for the monitoring of performance. The laboratory director of the referring laboratory is involved in the selection and annual review process. The Referral Laboratory must be Clinical Laboratory Improvement Amendment, (CLIA) certified for high complexity testing. The certificate must be appropriate for the level of testing the laboratory performs and bills.

Providence Laboratory Services may refer some testing to separately accredited laboratories. This policy defines the requirements for assuring timely, cost-effective quality testing, reporting results, retaining records, and reviewing and selecting referral laboratories.
