Our menu of test areas includes, but is not limited to:
- Cytogenetic diagnostics
- Cytopathology and fine needle aspiration
- Flow cytometry
- Immunology and Allergy Testing
- Molecular diagnostics
- Special chemistry testing including toxicology
- Special coagulation
- Surgical Pathology

We value all our clients and their patients, and understand their need for accurate and timely results. We provide STAT services 24/7 to the inpatient, emergency department, OR and trauma services. We also provide a rapid turn-around time whenever possible, usually within 24 hours.
A comprehensive alphabetical directory of tests is available online and is regularly updated. Visit our Laboratory Test Directory for more information.
Laboratory Services to the Emergency Department
The Hospital Laboratory provides comprehensive Priority 1, STAT and routine laboratory testing services to the Emergency Department 24/7 everyday of the year. The Laboratory is located above the Emergency Department and is staffed to support the Hospital and the Emergency Department. Laboratory specimens collected in the Emergency Department are sent to the Laboratory through the pneumatic tube system. Specimens with EMR orders that are received with a bar code go directly on the automated testing lines. Manually prepared specimens are hand processed and immediately tested. Test results are reported through the Laboratory Information System and are immediately available to the Emergency Department physicians via the EMR System.
The Medical Staff and the Laboratory Medical Directors work together to insure that all patient testing needed for Emergency Care are readily available to the Emergency Department physicians and nurses. Please see Laboratory Tests available on a STAT Basis. Additional testing can be obtained though faculty (pathologist) consultation. A pathologist is either immediately available or is on call for immediate consultation. In additional licensed laboratory staff is available on call 24/7 every day of the year.
Specimen collection and testing facilities
The faculty and staff of the Clinical Laboratory are committed to exceptional service for every patient sample that entrusted to us.
Patients may have their specimens collected at one of our several conveniently located patient service
centers. We will provide courier service for physicians who prefer to collect specimens in their offices.
Specialized medical directors are available to answer questions about routine and specialty test selection and interpretation of test results.
Testing is performed at our state-of-the-art clinical laboratories in Sacramento. Our fully-automated robotics line for chemistry and hematology testing—the first of its kind in the region—standardizes testing processes, eliminating variability in outcomes and reducing delays.
Referring physicians and patient care teams are quickly provided with accurate, efficient results.
We recognize that consulting with a pathologist is often critical in developing an informed treatment plan. As valued members of the patient’s health-care team, our subspecialty pathologists are available to consult with clinicians and take necessary and additional steps to resolve questions around difficult cases.
Consultation requests are offered by phone or digital consultation. Digital consultations allow our pathologists to share a whole slide digital image of the case through a Web-based interface program.
Our pathologists offer diagnostic and consultative services to inpatients, emergency medicine, trauma, hospital based clinics, primary care providers, medical specialists, surgeons, and other health-care professionals. They consider medical information and imaging findings, in conjunction with observations through the microscope and other laboratory tests, to provide comprehensive evaluation.
Our pathologists examine the full range of prostate specimens, from needle core biopsies to radical prostatectomies. In addition to routine histologic processing, our laboratory offers multiplex (dual chromogen) immunohistochemical staining for simultaneous assessment of p63, CK34bE12, and racemase in prostate biopsy sections.
