Who We Are

At South Texas Pathology Associates (STPA), our goal is to provide high quality, accurate information on both Anatomic and Clinical Pathology specimens to enable our colleagues to deliver the best patient care possible. Our laboratories are CAP-accredited, and we are able to assist in patient care 24 hours a day, seven days a week.

All members of STPA are Board Certified in Anatomic and Clinical Pathology, and many have fellowships and subspecialty training.

CLINICAL PATHOLOGY

STPA is committed to delivering excellence in Clinical Pathology services with full-time, board certified clinical pathologists on staff, assisted by other board certified pathologists with special interest and experience in clinical laboratory medicine. Working in concert with hospital administrators, STPA assures that newly developed tests and innovative technology are implemented in a timely fashion, and that all regulatory requirements are met.

Such techniques as molecular testing for infectious agents, specialized coagulation testing and fully automated chemistry testing allow both complex and routine tests to be processed quickly and accurately to meet clinical needs. For extremely urgent situations, STPA has consulted with physicians and management to provide appropriate bedside testing (point-of-care) protocols.

The Clinical Pathology service provided by STPA is specifically attuned to patient and clinician needs, with personal interpretation and consultation for situations such as complex blood banking, serologic, coagulation tests and others. In summary, STPA prides itself in providing full-service medical support for laboratory needs on multiple hospital and ER campuses.

 

PEDIATRIC AND WOMEN'S SERVICES

This service is staffed by board certified pediatric pathologists with special interests and years of experience in dealing with pediatric and perinatal disease. Our placental/perinatal service is quite active and includes the evaluation of a large number of placentas and tissues resulting from embryo/fetal loss.

In our study of placental pathology, our goal is to provide clinicians with the most currently available information regarding the correlation of our pathologic findings with potential adverse clinical outcomes, especially with respect to neurologic impairment. Tissues resulting from embryo/ fetal loss are subject to routine pathologic examination with the addition of cytogenetic/molecular studies and collaboration with specialists in the study of genetic/metabolic disease as indicated.

 

NEPHROPATHOLOGY AND TRANSPLANT PATHOLOGY

STPA has full-time pathologists with special interest and expertise in nephropathology and transplant pathology. Nephropathology services involve the diagnostic workup of kidney diseases, with biopsies referred to Methodist Specialty and Transplant Hospital from nearly all civilian hospitals in San Antonio as well as hospitals in Corpus Christi, Amarillo and Lubbock.

Solid organs transplanted at Methodist Specialty & Transplant Hospital include heart, kidney, liver and pancreas. The kidney program is the largest in Texas. The heart transplant program is currently housed at the Methodist Main campus. Transplant pathology is instrumental in determining type and severity of solid organ allograft dysfunction, as the treatment of allograft dysfunction depends on the pathologic interpretation of the biopsied organs.

 

IMMUNOHISTOCHEMISTRY

STPA's practice includes an active, comprehensive, fully-integrated immunohistochemistry section. Our anatomic pathology services, in particular, are tailored to the demands of many subspecialties. We use precise instrumentation together with a growing, ever-evolving list of reagent antibodies to provide fast, accurate and reliable immunostain results. In addition, we employ image analysis to selected immunostain marker evaluations, such as those used as breast prognostic markers.

 

CYTOPATHOLOGY SERVICE

STPA's practice includes a very active cytopathology section with a fine-needle aspiration biopsy service. We have board certified cytopathologists in our practice who are able to offer Pathologist directed superficial/ palpable aspirates as needed. In addition, we service a large radiologist-directed FNA practice, which includes specimens from CT, ultrasound and Special Procedure suites, as well as an Endoscopic Ultrasound (EUS) FNA practice servicing gastroenterologists specially trained in this procedure.

A pathologist works in concert with the radiologist/gastroenterologist to prepare and examine the specimen for all cytopathology procedures. This allows for rapid evaluation to ensure that the specimen can be collected for routine cytologic interpretation as well as for special testing, such as microbiologic cultures, flow cytometry and special molecular testing. Our practice also includes a large number of non-gynecologic cytopathology samples (body fluids, washings and brushings, etc.) and many fine needle aspirates sent from outpatient clinics and doctors' offices.

STPA no longer interprets gynecologic Pap smears, and any we receive are sent to an outside gynecologic Pap smear reference laboratory. We have fully integrated our cytopathology service with hematopathology, employing both in-house flow cytometric analysis and tissue immunocytochemistry in our evaluation of lymphoproliferative and other hematologic processes frequently encountered in cytopathology practices.

 

HEMATOPATHOLOGY

STPA's hematopathology section directs the diagnostic evaluation of lymph nodes and bone marrow biopsies, aspirates and other hematoproliferative tissue samples, including those referred from our active cytopathology fine needle aspiration biopsy service. We incorporate appropriate ancillary cell characterization data including in-house immunohistochemistry and flow cytometry, as well as cytogenetic and molecular studies. Our adult hematopathology service is staffed by board certified hematopathologists. This service maintains a close relationship with the Texas Transplant Institute, facilitating close cooperation with the solid organ and bone marrow transplant sections in the diagnosis of post transplant lymphoproliferative disorders.

Pediatric hematology specimens are handled by the pediatric pathology service, with the same ancillary testing.

Our hematopathology service is able to maintain coverage seven days a week to provide routine and emergency services to patients with hematologic disorders. Flow cytometry services are provided routinely six days a week and on Sundays on an emergent case-by-case basis.
