Broad Clinical Labs Sets New GUINNESS WORLD RECORDS™ Title for Fastest DNA Sequencing Technique

BOSTON, Oct. 16, 2025 /PRNewswire/ — Broad Clinical Labs (BCL), in collaboration with Roche Sequencing Solutions and Boston Children’s Hospital, today announced official recognition by Guinness World Records for achieving the fastest DNA sequencing technique to date. Leveraging Roche’s new SBX sequencing technology¹ and a streamlined, integrated workflow, the teams completed sequencing and analysis of the whole human genome in less than 4 hours, surpassing the previous benchmark of 5 hours and 2 minutes.

The team subsequently applied this process to samples obtained from the Boston Children’s Hospital neonatal intensive care unit to demonstrate a same day workflow from blood to report. The work was described today in the New England Journal of Medicine.

This achievement demonstrates that it is possible to create a timeframe in which a lab can receive a sample and return actionable information back in under 8 hours and still keep pace with a high-volume neonatal intensive care unit — a great improvement from current timeframes which are at least two days but more frequently greater than 5 days. This difference could be profoundly beneficial.
