DNA sequencing can play an important role in clinical trials, providing valuable insights into genetic variations and facilitating research in personalised medicine. However, choosing the right laboratory for DNA sequencing is crucial to ensuring precise results. In this blog post, we will discuss the key factors to consider when selecting a lab for clinical trial DNA sequencing, including expertise, technology, quality control, turnaround time, and data security.


One of the first considerations when choosing a lab for clinical trial DNA sequencing is their expertise in the field. Look for laboratories with a proven track record in sequencing for clinical trials and assess their experience in handling study designs similar to yours. You should also consider their knowledge of regulatory requirements and compliance with industry standards to ensure the integrity and validity of their data. Generally, a lab with specialised expertise and experience in clinical trial sequencing will be better equipped to handle the specific challenges and intricacies of your study.

Technology and infrastructure

The next factor to consider is the laboratory's technology and infrastructure. DNA sequencing technologies have evolved rapidly, so it is essential to work with a lab that utilises state-of-the-art equipment and methods. Inquire about the sequencing platforms they employ, such as next-generation sequencing (NGS), and their ability to handle the volume and complexity of your study's DNA samples. You should also ask about their bioinformatics capabilities, as analysis and interpretation of the data they collect is vital to understanding the sequencing results.

Quality control and accreditation

Quality control measures are crucial to ensuring the reliability and accuracy of sequencing results. You should always check if the lab has appropriate accreditation and certifications, such as ISO 15189 or CLIA (Clinical Laboratory Improvement Amendments), which both show that the lab adheres to rigorous quality standards. In the same regard, you should inquire about their quality control processes, including sample tracking, data validation, and error detection.

Turnaround time 

Timely delivery of sequencing results is essential in clinical trials, as it impacts decision-making and study progress. Discuss the expected turnaround time with potential labs and assess their ability to meet your study's timeline. Consider factors such as sample processing efficiency, sequencing capacity, and data analysis speed. A lab with efficient workflows and streamlined processes can speed up the sequencing process without compromising data quality. However, striking a balance between turnaround time and data accuracy is imperative to ensure reliable and accurate results.

Data security and confidentiality 

Protecting patient data is of the utmost importance in clinical trials. To be sure that the data in your study remains private, you should ask about the lab's data security protocols and their compliance with relevant privacy regulations, such as the General Data Protection Regulation (GDPR) or the Health Insurance Portability and Accountability Act (HIPAA). It's also important to assess their data management practices, including data storage, encryption, and access control, to ensure the confidentiality and privacy of participant information.


Selecting the right lab for clinical trial DNA sequencing is a critical decision that can significantly impact the success and validity of your study. By considering factors such as expertise, technology, quality control, turnaround time, and data security, you can make an informed choice that aligns with your study objectives, ensuring accurate and reliable sequencing results for your study.
