Selecting Control Tissue for Immunohistochemical Assays: Factors and Collaboration
Summary
- Selection of appropriate control tissue is crucial for validation of immunohistochemical assays.
- Factors such as tissue type, antigen expression, and sample preparation must be considered.
- Collaboration between pathologists and laboratory professionals is essential for ensuring accurate results.
Introduction
Immunohistochemical assays play a vital role in the diagnosis and treatment of various diseases in medical labs. These assays rely on the use of control tissue to validate the accuracy and reliability of the results. Selecting the appropriate control tissue is essential to ensure the validity of the testing process. In this article, we will discuss the factors that should be taken into consideration when selecting control tissue for validation of immunohistochemical assays in medical labs in the United States.
Factors to Consider
Tissue Type
The choice of control tissue depends on the type of sample being tested. Different tissues have varying levels of antigen expression, which can affect the outcome of the assay. It is important to select control tissue that closely resembles the target tissue to ensure accurate results. For example, if the target tissue is lung tissue, the control tissue should also be lung tissue to minimize variations in antigen expression.
Antigen Expression
Another important factor to consider when selecting control tissue is the expression of the target antigen. Control tissue should have similar levels of antigen expression as the target tissue to provide a reliable comparison. If the control tissue has low antigen expression, it may produce false-negative results, while high antigen expression may result in false-positive results. It is crucial to choose control tissue with consistent antigen expression to ensure the accuracy of the assay.
Sample Preparation
The way in which the control tissue is prepared can also impact the validity of the immunohistochemical assay. Proper sample preparation techniques must be followed to ensure that the control tissue is suitable for comparison with the target tissue. Factors such as fixation, embedding, and sectioning can affect the quality of the tissue sample and the accuracy of the results. It is essential to adhere to standardized protocols for sample preparation to minimize variability and ensure the reliability of the assay.
Collaboration
Collaboration between pathologists and laboratory professionals is essential for the successful validation of immunohistochemical assays. Pathologists play a key role in identifying the appropriate control tissue based on their expertise in tissue morphology and antigen expression. Laboratory professionals are responsible for ensuring that the control tissue is prepared and analyzed correctly to provide accurate results. By working together, pathologists and laboratory professionals can ensure that the control tissue selected is suitable for validation of the immunohistochemical assay.
Conclusion
Selecting the appropriate control tissue is crucial for the validation of immunohistochemical assays in medical labs. Factors such as tissue type, antigen expression, and sample preparation must be taken into consideration to ensure the accuracy and reliability of the results. Collaboration between pathologists and laboratory professionals is essential for identifying and preparing control tissue that closely resembles the target tissue. By carefully considering these factors, medical labs in the United States can ensure the validity of their immunohistochemical assays and provide accurate diagnostic information for patients.
