Led by pathologists renowned for diagnostic excellence, the Department of Pathology at City of Hope combines state-of-the-art laboratories equipped with the latest diagnostic techniques and advanced instrumentation with superior investigative skills to accurately and rapidly identify even the rarest and most complex diseases. Our experts provide comprehensive services, from initial diagnosis to monitoring of prognostic indicators throughout the treatment process. Our team also maintains a blood bank and offers a full complement of services relating to blood and bone marrow donors.
Pathology Consultation Services
Our Pathology Consultation Services offers a comprehensive program to fulfill all pathology needs. Physicians at City of Hope and from around the world choose to submit their biopsy samples here because our laboratories are of the highest caliber and our team of pathologists are recognized experts in diagnosing and monitoring disease.
Our team takes a coordinated and cooperative approach, and final interpretations are only made at a daily consensus conference of senior staff, reinforcing the validity of the initial pathologist’s opinion and minimizing any possibility of error.
Rapid, Integrated Results at Competitive Prices
Our highly efficient support staff – from receptionists to transcriptionists to managers – helps deliver complete, accurate reports quickly to the requesting physician. The results of multiple tests are combined into one integrated report, for quick, clear access to priority tests. In most cases, results are obtained within 24 to 48 hours, with automatic faxing capabilities once the reports are signed out. As a nonprofit institution, we are able to offer highly competitive prices for our services. Our regular rates are low, and contracts can be negotiated for prospective high-volume clients. Professional revenues generated are used to support the department’s research activities.



Pathology Case Submission

Cases submitted to a specific pathologist will be read by the designated party. Otherwise we will assign the case to an appropriate investigator.

Always include the patient's clinical history along with referring physician's name, phone and fax numbers on the requisition form.

Send cases to:

Pathology Customer Service

Customer and Financial Services
We are committed to providing superior pathology consultation services and supporting your needs in an increasingly competitive and cost-conscious medical marketplace.
To that end, we endeavor to complete your case as quickly as technically possible while maintaining our high quality standards.
For your convenience, we will bill third party payers. Simply complete the insurance information on the requisition form. In the absence of complete third party information, the referring pathologist or facility will be billed.
Unfortunately, due to Medicare regulations, we are not able to bill a third party payer if the patient is an inpatient at the referring facility. In this case, the referring institution will be billed. However, we do offer contract prices for these cases with highly competitive rates.
Specimen Collection
We offer free courier services for facilities located in the Southern California area. For facilities outside of Southern California, please call 626-256-HOPE (4673), ext. 63875, to coordinate pick up.



Pathology Laboratories

Our immunohistochemistry laboratory includes three high-volume automated immunostainers using highly advanced epitope retrieval techniques.  We offer complete immunohistochemistry characterization of surgical and cytologic specimens, including estrogen and progesterone receptors and over 100 other monoclonal and polyclonal antibodies. Each year, our hematopathology laboratory performs cytochemistry on more than 1,000 cases of acute leukemia and processes thousands of bone marrow specimens annually.
Flow Cytometry
Our flow cytometry laboratory uses high-capacity instruments to analyze thousands of samples annually to measure a variety of parameters, including cell surface antigens. The presence or absence of certain cell surface antigens has shown great prognostic value in various neoplasia, where treatment protocols can be optimized by customizing the type of treatment based on the types of cell surface antigens present. We provide comprehensive cytochemical and immunophenotypic characterization of leukemias and lymphomas; B and T cell subset analysis for immunodeficiencies; stem cell counts; solid tumor DNA content and cell cycle analysis.
Every year, the cytogenetics laboratory processes a heavy volume of neoplastic specimens, utilizing both conventional cytogenetics as well as fluorescence in situ hybridization (FISH). FISH has become the recognized gold standard in determining the likely course of disease and appropriate treatment in leukemias such as chronic lymphocytic.
Molecular Biology
Our molecular biology laboratory performs Southern blot hybridization, polymerase chain reaction, and in situ hybridization studies for B and T cell gene rearrangements, many different chromosomal translocations for lymphoma and leukemia, including t(14;18), t(9;22), t(15;17), and Epstein-Barr virus. Many of the molecular tests can be performed on paraffin-embedded tissue.
Laboratory accreditation, certification and licensing
The Consultation Services Laboratories at City of Hope are fully accredited by the College of American Pathologists (CAP #22900-01), certified under the Clinical Laboratory Improvements Amendments of 1988 (CLIA '88, ID No. 05D0665695) and licensed by the state of California (CLF 268).

The laboratories participate in the CAP's external proficiency survey program for flow cytometry, immunophenotyping, immunohistochemistry, cytogenetics and molecular oncology. Specific details on our survey performance are available upon request.

Specimen Draw and Shipping Requirements

Results for STATs, pre-BMT's and newly diagnosed leukemias are available within seven days. All others are available in seven to 10 days but our goal is to report results as soon as they are available. Complex studies may require additional days. Specimens are accepted Monday through Friday, 8 a.m. to 5:30 p.m.
Drawing specifications
  • Leukemia and myelodysplastic syndromes: A bone marrow aspirate is the specimen of choice in most cases of leukemia, myelodysplastic and myeloproliferative disorders.
  • Leukemia cytogenetics: Obtain 1 to 2 ml of bone marrow (minimum 0.5 ml) in a heparinized syringe (approximately 500 USP sodium heparin per ml of specimen) and transfer the specimen into a green top sodium heparin tube. Keep at room temperature and ship as soon as possible.
  • Leukemic peripheral blood: Draw 5 to 20 ml of peripheral blood into a green top sodium heparin tube. Mix well by inverting. Keep at room temperature and ship as soon as possible.
  • Lymphoma and solid tumor cytogenetics: Bone marrow core biopsies should be placed in HBSS or RPMI medium.
Flow cytometry / molecular diagnostics
The laboratory is open Monday through Friday, 8 a.m. to 5 p.m.
Drawing specifications
  • Peripheral blood: For leukemia and lymphoma panels, draw six green top tubes (sodium herapin) and one purple top tube. Maintain at room temperature and ship as soon as possible. ACD tubes are acceptable. Sodium lithium should not be used.
  • Bone marrow: Draw at least one purple top tube, maintain at room temperature and ship as soon as possible. ACD and sodium heparin tubes are acceptable.
