Reliable molecular testing starts with confident specimen quality.

Verifying specimen integrity is essential for generating accurate molecular diagnostic results, yet traditional extraction controls do not assess sample quality or collection effectiveness. This technical note examines the use of Beta-Actin as an internal control to evaluate specimen integrity and DNA extraction performance, providing an additional layer of confidence for molecular testing workflows.

Key topics include:

• The role of Beta-Actin as an internal control for assessing specimen integrity
• Limitations of traditional external extraction controls
• Strategies for verifying specimen collection quality and DNA extraction performance
• Applications for low-yield and self-collected specimens
• Considerations for improving the reliability of molecular diagnostic assays

As molecular testing continues to evolve, incorporating internal specimen quality controls can strengthen assay reliability and increase confidence in test results. Learn how Beta-Actin can enhance molecular workflows by providing additional verification of specimen integrity and extraction success.
