    This presentation will introduce the concept of analytical reference standards for immunohistochemistry, provide some examples of the different technology as well as examples of their use.

    Since its inception, immunohistochemistry (IHC) has been called a “stain” principally because of its origin as a byproduct of traditional histochemistry. Simply, a tool to identify specific targets in cells and tissues that could not be distinguished by traditional morphologic or histochemical techniques. There is a great deal of controversy surrounding this notion. A recent editorial by B. Magnani and C. Taylor has brought the issue back to forefront of the histopathology community. Over the last 25 years, IHC has evolved into a complex testing modality. IHC has developed into a “test” that requires both qualitative AND quantitative interpretation, ushering in the era of companion diagnostics. Unfortunately, IHC test quality assurance is still grounded in subjective pass/fail interpretation based on non-standardized control tissues that are insensitive and irreproducible. The major obstacle has been the lack of appropriate tools to assess assay performance during the analytical phase, similar to what is done in clinical pathology laboratories. However, IHC calibration technology is now available that can establish analytical standardization that will help address both interpretive and technical errors, perhaps providing a means to better understand pre- and post-analytical phases. This presentation will introduce the concept of analytical reference standards for immunohistochemistry, provide some examples of the different technology as well as examples of their use.

    This webinar will review TCs and their potential impacts.

    Histologists and surgical pathologists are familiar with the phenomenon of the tissue contaminant (TC) or floater.  Although TCs are unusual events, and the majority of contaminants are fragments of benign tissue they often receive limited attention until an error occurs.  This webinar will review TCs and their potential impacts.

    This webinar will introduce three areas: diagnosis, research, and education, where histology play an important role in Vet Medicine.

    Histology plays a pivotal role in Veterinary Medicine and histotechnologists are indispensable. For example, veterinary pathologists at the University of Missouri’s Veterinary Medical Diagnostic Laboratory read more than 10,000 biopsy cases and more than 1,000 autopsy cases annually, and all tissue samples are proficiently prepared by histotechnologists. Many scientists in the College of Veterinary Medicine and across the campus use histological analysis to accelerate scientific discoveries. Histology is also an integral part of education in Vet School and is utilized in various areas including study of diseased tissues for students and residents. In this webinar, I will introduce three areas: diagnosis, research, and education, where histology play an important role in Vet Medicine.

    The session will start with an introduction to main concepts such as; the difference between antibody validation vs. verification, explaining the clinical risk to patients, the usefulness of a risk matrix covering the use of antibodies from low risk to high risk, and how this is decided.

    The session will start with an introduction to main concepts such as; the difference between antibody validation vs. verification, explaining the clinical risk to patients, the usefulness of a risk matrix covering the use of antibodies from low risk to high risk, and how this is decided. It will highlight the risk matrix we use in my lab in Melbourne, Australia, and offer it up for discussion with the audience. I hope to cover the similarities and differences (if any) between the Australian and American lab accreditation systems on the subject of antibody validation, especially with IVD, RUO, and ASR antibody classifications.

    As Histology and IHC labs continue to grow, the often-forgotten science of slide surface chemistry needs to be understood to minimize expensive test failures. This webinar will dive into this topic to help improve lab results.

    With all the advancements in Histology over the past 100 years, placing tissue sections on glass slides continues to be a tried-and-true technique for preparing biopsies for microscopy. Sufficient adhesion of tissue sections to a glass slide is important for obtaining a quality section. With some of the automated stainers and harsher staining protocols used in Immunostains (IHC) testing, tissue adherence is an ever important, yet often overlooked, factor for preparing biopsies. In addition, automated staining platforms may rely on diffusion and mixing of reagents on a slide’s surface, so any anomalies in the charge on the slide’s surface may result in inconsistent staining results if reagents don’t disperse evenly over the tissue. The Mayo Clinic IHC Lab has placed a great deal of emphasis on understanding the basic, but hugely important, science of slide surface chemistry. We’ve performed extensive testing of parameters which may affect the charge on a slide’s surface regarding tissue adhesion and staining quality such as baking time and temp, slide type, tissue type, the age of the charged slide, and storage and handling. This has led us to major improvements in managing slide inventory, as well as making better choices for purchasing slides. As Histology and IHC labs continue to grow, the often-forgotten science of slide surface chemistry needs to be understood to minimize expensive test failures.
