Pathology Laboratory Associates

Pathology Laboratory Associates, Inc. (PLA) is an independent pathology group primarily located in Tulsa Oklahoma with board-certified pathologists and pathology assistants. PLA offers anatomic/surgical and clinical pathology services, cytology/cytopathology, bone marrow evaluation and ancillary studies, and performance and interpretation of fine-needle aspirations.

PLA provides medical lab directorship services for a number of regional hospitals and clinics throughout Oklahoma and Kansas. Our team offers assistance in laboratory planning, design, management and marketing functions.

PLA was founded over 40 years ago and has been a pioneer in the use of laboratory analytics and helped innovate and develop important industry software tools. The Cerner Classic Laboratory Information System was fostered by PLA founders and others in the 1990’s and later influenced paradigms in medical industry software.

Clinical Pathology

The science and practice of medical diagnosis by laboratory examination and analysis of blood, tissue specimens (BIOPSIES), body fluids and other samples. Clinical pathology is subdivided into Hematology, Coagulation, Flow Cytometry, Molecular Pathology, Microbiology, Virology, Bacteriology, Clinical Chemistry, Immunology/Serology, and Drug testing.

Clinical Chemistry

Clinical chemistry is a quantitative science that is concerned with measurement of amounts of biologically important substances (called analytes) in body fluids. The methods to measure these substances are carefully designed to provide accurate assessments of their concentration. The results of clinical chemistry tests are compared to reference intervals o/r a medical decision level (MDL) to provide diagnostic and clinical meaning for the values.


Coagulation medicine offers expert interpretations of coagulation profiles and consultations in the diagnosis and management of patients with bleeding or clotting disorders. A battery of tests is offered using advanced and progressive technologies. Pathology Consultation Services are offered for patients whose blood has been tested in the laboratory.


Cytopathology is a branch of pathology that evaluates and diagnoses tissue or fluid samples on the cellular level. Cytopathology is generally used on samples of free cells or tissue fragments.


Dermatopathology is a joint subspecialty of dermatology and pathology or surgical pathology that focuses on the study of cutaneous diseases at a microscopic and molecular level. It also encompasses analyses of the potential causes of skin diseases at a basic level.

Flow Cytometry

Flow cytometry is a technique used to detect, quantify and diagnose a disease process by examination of identifying cell markers on the surface of cells or particles. The primary use of this technique is in the diagnosis of hematologic malignancies or abnormalities involving the blood, bone marrow, fluids or tissues.

Gastrointestinal Pathology

Gastrointestinal pathology is the subspecialty of surgical pathology which deals with the diagnosis and characterization of neoplastic and non-neoplastic diseases of the digestive tract and accessory organs, such as the pancreas and liver.

Genitourinary Pathology

As a medical specialty, genitourinary pathology is the subspecialty of surgical pathology which deals with the diagnosis and characterization of neoplastic and non-neoplastic diseases of the urinary tract, male genital tract and testes. However, medical disorders of the kidneys are generally within the expertise of renal pathologists. Genitourinary pathologists generally work closely with urologic surgeons.

Head & Neck Pathology

Head and neck pathology focuses on a large cross-section of the head and neck region to diagnose neoplastic and non-neoplastic diseases of the oral cavity, oropharynx, larynx, nasal cavity, nasopharynx, salivary glands, thyroid gland, parathyroid glands, maxillofacial region, and other head and neck sites.


Hematopathology is the study of neoplastic and non-neoplastic diseases and disorders affecting blood cells, their production, and any organs and tissues involved in hematopoiesis, such as bone marrow, lymph nodes, the spleen, and the thymus.


Immunology is a branch of medicine that deals with immune responses associated with disease. It includes the study of the pathology of an organism, organ system, or disease with respect to the immune system, immunity, and immune responses.


Microbiology is the scientific study and diagnosis of diseases caused by microorganisms, encompassing numerous sub-disciplines including virology, bacteriology, protistology, mycology and parasitology.

Molecular Pathology

Molecular pathology is an emerging discipline within pathology which is based on the detection or quantitation of specific RNA or DNA molecules within tissues, blood or fluid samples. This is useful for diagnosis, treatment and prognosis of many neoplastic and infectious diseases.

Multidisciplinary Breast Pathology

The breast pathology specialty focuses on the classification of benign and malignant breast disease to achieve optimal therapy.  This involves close coordination with breast specialists in Radiology and Surgery.  Hormone and growth factor receptors are evaluated to allow proper therapy for breast carcinomas.

Renal Pathology

Kidney pathology is a subspecialty of anatomic pathology that deals with the diagnosis and characterization of medical diseases of the kidneys. In the academic setting, renal pathologists work closely with nephrologists and transplant surgeons, who typically obtain diagnostic specimens via percutaneous renal biopsy.

Soft Tissue

Soft tissue pathology is a subspecialty of surgical pathology which deals with the diagnosis and characterization diseases of the soft tissues, such as muscle, adipose tissue, tendons, fascia, and connective tissues. Many malignancies of the soft tissues are challenging for the pathologist to diagnose through gross examination and microscopy alone, and additional tools such as immunohistochemistry, electron microscopy, and molecular pathology techniques are sometimes employed to obtain a definitive diagnosis.


The practice of surgical pathology gives diagnosis of disease or disease in cases where tissue is surgically removed from a patient. This is usually performed by a combination of gross and histologic examination of the tissue, and may involve evaluations of molecular properties of the tissue by immunohistochemistry or other laboratory tests.

Transfusion Medicine

Transfusion medicine is the branch of pathology that includes the transfusion of blood and blood components including aspects related to preservation of our precious donated blood product supply. Laboratory management and understanding of state and federal regulations related to blood products and its administration to patients are integral to this specialty.
