LSU Clinical Pathology

Welcome to the Clinical Pathology Division for the Department of Pathology. Dr. James Cotelingam serves as the Medical Director and Ms. Susan Dust as the Technical Director for the Division of Clinical Pathology.  The Division of Clinical Pathology has eight full time subspecialty trained and Board Certified Faculty. Oversight is provided for our Hematopathology, Wet Hematology,  Coagulation, Flow Cytometry, Blood Bank,  Apheresis, Routine and Special Chemistry and Point of Care, Lab Information, Microbiology, Virology, Parasitology, Cytogenetics, and Molecular Genetics Services.

Our professional staff pride themselves in providing timely, accurate results with direct one on one customer interactions. The clinical pathologists and section branch heads welcome every opportunity to discuss a case directly with the clinician in order to provide the patient with the highest quality care available on the market.

Our laboratories are inspected and accredited by Joint Commission and CAP. Additionally, many of our team members serve as CAP inspectors including Dr. Diana Veillon, Hematopathologist, who also served as a CAP State Commissioner.

Each of our team members is highly qualified, licensed, and has many years of experience in their field of expertise. Clinical Pathology Faculty members are not only involved in clinical services, but are actively involved in educational roles and research. Expertise accrued is readily shared outside the institution in the form of numerous publications, posters, and speaking engagements.

Our mission and commitment is to diagnostic services, teaching, and research. At our daily multimodality consensus conference, clinical materials and data are reviewed and reported.  Our diagnostic services are primarily for the patients of University Health, The Feist-Weiller Cancer Center (FWCC), our bone marrow transplant unit, and Consultative Services on pathologic material accompanying patients referred to our facilities for a second opinion and treatment.

Clinical Subspecialties

Blood Bank/Transfusion Medicine

The Blood Bank and Transfusion Medicine service provides support for patients at University Health, FWCC and our level I Trauma Center. We offer compatibility testing, transfusion reaction work-up, RhoGAM evaluation, therapeutic phlebotomy and a 24 hour a day/7 days a week therapeutic apheresis and consultative services. Regular utilization reviews provide feedback to our clinicians about appropriate product utilization. This service is accredited by the ABBB, FDA, CAP, and Joint Commission. Full time oversight is provided by a medical director.

Chemical Pathology

The Chemistry Lab provides a comprehensive menu of patient care testing that includes Routine Chemistries, Serologic studies, and Toxicology studies including Therapeutic Drug Monitoring. Special chemistry studies performed include evaluation of Hemoglobins and Proteins by capillary electrophoresis and Antibody studies for the diagnosis of immunologic diseases. Pathologists and allied scientists provide laboratory oversight and clinical consultation services and perform diagnostic interpretation of several special chemistry studies.


The Multi-Disciplinary Hematopathology service includes three Hematopathologists, a Molecular Pathologist, a Cytogeneticist, and Blood Banker, all with Subspecialty Boards. Our technical staff have many years of experience in Hematology, Flow Cytometry, Coagulation, Molecular Genetics, Cytogenetics and Bone Marrow acquisition.  We perform 8-color flow cytometry, and comprehensive FISH and molecular diagnostics testing menus.  Our Multi-Modality review of clinical material allows integration of morphologic findings with all special, state of the art, studies.  The presence of our clinicians at daily sign-out conference for clinicopathologic correlation ensures the best in patient care.


The Pathology informatics branch uses cutting-edge clinical information systems to support anatomic pathology and clinical pathology daily operations. It actively interacts with the hospital electronic medical record system EPIC and other clinical departments’ information systems. In anatomic pathology, the branch manages the installation and maintenance of CoPath, as well as gross and microscopic imaging databases using Apollo PathPACS.  In clinical pathology, it supervises the operations of Sunquest, middlewares, Citrix, and various interface engines.  Faculty and staff participate in resident teaching and research.  It is an essential component of hospital-wide clinical informatics.  A full-time pathologist with computer science and informatics trainings oversees the informatics service, education and research.
Medical Microbiology

The Medical Microbiology branch of the Clinical Laboratory performs a comprehensive menu of testing including Bacteriology, Mycology, Parasitology and Virology. Faculty and staff participate in infectious disease rounds, infection control committee meetings, and in epidemiologic studies.  Oversight is offered by a full-time Pathologist.

Molecular and Cytogenetics

Molecular and Genetic testing services provided include Cytogenetics, FISH, and PCR for the evaluation of constitutional abnormalities, hematologic diseases including leukemia and lymphoma, evaluation of suspected hypercoagulability, and molecular genetic studies essential for the diagnosis and treatment of patients with other cancers. These studies complete or enhance the diagnostic testing services for both Anatomic and Clinical Pathology, particularly in the evaluation of tumors.  A Molecular Pathologist and a cytogeneticist provide diagnostic and clinical consultative services. 

 Frequently Asked Questions:

  • What is Clinical Pathology?
    • Most individuals refer to this division as the "Clinical Laboratory". The Clinical Lab is a large portion of Clinical Pathology but there are other services like apheresis, bleeding times, point-of-care testing, etc. that are also part of Clinical Pathology.
  • What type of specimens and testing is performed in this area?
    • Blood, urine, stool, sputum and numerous other specimens are sent for stat, routine and esoteric testing.
  • What is an esoteric test?
    • A test that requires a higher level of expertise and technical abilities.
    • Some of the sections that provide specialize testing include, but are not limited to, Transfusion Services, Molecular Testing, Cytogenetic Testing for Tumor and Congenital Conditions, Virology and support for our Trauma Center and Regional Burn Unit.
  • What is a reference test?
    • Typically, no laboratory can perform every possible test as there a literally thousands many of which require highly specialized certification, equipment and personnel. For these type of tests a facility will send the specimen to another facility that specializes in that test. In some cases specimens are sent to other facilities due to cost constraints because of low volume requests.
  • Does LSU Health Shreveport Pathology serve as a reference lab to other facilites?
    • Yes.
    • Our facility receives and performs testing for other facilites as our technical and professional staff possess high levels of expertise in many of the cutting edge technology available on the market.
    • Our personnel also excel in academics teaching other technical and professional level individuals so they too can provide a mechanism of providing higher quality patient care to both local and national communities.
