In molecular diagnostics, maintaining the quality and integrity of collected specimens is crucial for obtaining reliable results. While external controls, such as a bacteriophage, validate the nucleic acid extraction process, they do not assess specimen integrity or the effectiveness of the collection method itself. This gap in control introduces potential risks, especially for self-collected or low-yield samples like serum.
Beta-Actin, a well-established housekeeping gene, is known for its consistent detection and expression across a variety of sample types and has been widely used in molecular assays. This study explores the potential of Beta-Actin as an internal control to verify specimen integrity and ensure effective DNA extraction. By integrating Beta-Actin into our clinical workflows, we aim to introduce an additional layer of control that will enhance the reliability and adaptability of our assays.
