Reference labs are usually private, commercial facilities that do both high volume and specialty (high complexity and/or rare) laboratory testing. Most, if not all, inpatient and many outpatients seen by hospital-affiliated physicians require tests performed by hospital labs. The specific pathology services would include both anatomic (surgical pathology, cytopathology, autopsy) and clinical (laboratory medicine) pathology at most hospitals. Types of pathology labsĪlmost all hospitals contain a laboratory to support the clinical services offered at the hospital. While some have postulated that we are moving toward a gene/mutation driven categorization of tumors replacing disease site clinics and treatment planning (e.g., PIK3CA mutated carcinomas instead of “ovarian” cancer or “breast” cancer), data is accumulating that histology, morphology, disease site location and microenvironment in addition to genomic changes are still important factors in understanding the disease biology for treatment planning. It is not only important to obtain sufficient tissue for a specific diagnosis of malignancy, but for many malignancies, additional tissue is required for prognostic and predictive ancillary studies. Data on markers with prognostic and predictive significance are also routinely incorporated into pathology reports, allowing individualized treatment plans for patients. There are hundreds of varieties tumors, most with characteristic biology, that require accurate diagnosis by pathologists. The goal of pathology examination of tissue is to provide accurate, specific and sufficiently comprehensive diagnoses to enable the treating physician to develop an optimal plan of treatment. Policies supporting this practice are written into the bylaws of most hospitals and are regularly monitored by hospital tissue committees and accrediting agencies. The diagnosis of cancer is not conclusively established, nor safely assumed, in the absence of a tissue diagnosis, nor should definitive therapy for cancer, with rare exception, be undertaken. The following section reviews the importance and key objectives in the pathologic evaluation of tissue and provides information on the types and members of the pathology laboratory. The delivery of a specimen to the pathology laboratory initiates a complex series of events resulting in a pathologic diagnosis/interpretation.
