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 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.

  • Counter-intuitive though it might seem, a prostate cancer diagnosis shouldn’t always lead to immediate prostate cancer treatment. Although prostate cancer is the second-leading cancer killer of men, behind lung cancer, and causes more than 29,000 deaths in the U.S. each year, in many cases, the tumors are...
  • Radiology is one of the cornerstones of any hospital. It is a key diagnostic branch of medicine essential for the initial diagnosis of many diseases and has an important role in monitoring a patient’s treatment and predicting outcome. Radiology is the specialty considered to be both the “eyes” and “ears” of med...
  • Donating blood and platelets saves lives. We all know this. Yet every summer, potential blood donors become distracted by vacations and schedule changes. As a result, blood donations fall dramatically across the nation, leaving hospitals frantically trying to bring in much-needed blood for their patients. Earli...
  • To be a great cancer hospital, you need a great oncology program. Just ask City of Hope – and Becker’s Hospital Review. The health care publishing industry stalwart, described as the “leading hospital magazine for hospital business news and analysis for hospital and health system executives,” recently selected ...
  • Diagnostic errors are far from uncommon. In fact, a recent study found that they affect about 12 million people, or 1 in 20 patients,  in the U.S. each year. With cancer, those errors in diagnosis can have a profound impact. A missed or delayed diagnosis can make the disease that much harder to treat, as the Ag...
  • Eleven years ago, lymphoma patient Christine Pechera began the long road toward a cancer-free life. She had been diagnosed with non-Hodgkin lymphoma and told by doctors elsewhere that her lifespan likely would be measured in months, not years. Refusing to give up, she came to City of Hope for a second opinion. ...
  • Brain surgery is not for the faint of heart. It takes courage, as well as curiosity and compassion. The truly great surgeons also have a desire to find new, and better ways, of healing the brain. Enter Behnam Badie, M.D., chief of neurosurgery at City of Hope. Now a pioneer in brain tumor treatment, Badie enter...
  • Elizabeth Budde, M.D., Ph.D., wants to encourage infighting. She aims to turn the immune system on itself — to the benefit of patients with acute myeloid leukemia, or AML. AML arises when abnormal white blood cells grow out of control, amassing in the bone marrow and interfering with normal blood cell developme...
  • Six, to date; more soon. Outpatient bone marrow transplants, that is. Finding new ways to deliver quality care with the greatest benefit is a priority for a patient-centered institution like City of Hope. For example, not every bone marrow transplant patient needs to check into the hospital for treatment. In fa...
  • The best measure of success in the fight against cancer is in lives saved and families intact, in extra days made special simply because they exist. Yuman Fong, M.D., chair of the Department of Surgery at City of Hope, understands what precedes that special awareness. When cancer strikes, one minute a person ma...
  • In cancer, expertise matters. So do survival rates, patient safety, patient services and many other factors. City of Hope understands this, as does U.S.News & World Report. The magazine’s 2014-2015 list of best hospitals for cancer once again includes City of Hope, ranking the institution 12 out of 900 elig...
  • At 29, Kommah McDowell was a successful young professional engaged to be married to her best friend. She worked in the financial services sector and kick-boxed to keep in shape and to relax.
