Reducing Lab Turnaround Times: A Data-Driven Approach

Turnaround time (TAT) is one of the most critical metrics for genomics laboratories. Clients expect fast results, and labs that deliver consistently shorter TATs gain competitive advantages, higher client satisfaction, and increased revenue. However, reducing TAT requires more than just working faster—it demands a systematic, data-driven approach to identifying and eliminating bottlenecks.

Why Turnaround Time Matters in Genomics

In genomics, turnaround time directly impacts research timelines, clinical decision-making, and client satisfaction.

Client Impact

• Research timelines - Delayed results push back publication deadlines and grant milestones
• Clinical applications - Longer TATs delay patient diagnosis and treatment decisions
• Project planning - Unpredictable TATs make it difficult for clients to plan downstream work
• Competitive pressure - Clients will choose labs with faster, more reliable TATs

Business Impact

• Client retention - Faster TATs improve client satisfaction and retention
• Revenue growth - Shorter TATs allow labs to process more orders
• Premium pricing - Labs with consistently fast TATs can command premium pricing
• Market reputation - TAT performance becomes part of your lab's brand

Industry Benchmarks

Typical genomics lab TATs vary by service:

• Whole Genome Sequencing - 4-8 weeks standard, 2-3 weeks expedited
• Whole Exome Sequencing - 3-6 weeks standard, 2-3 weeks expedited
• RNA Sequencing - 2-4 weeks standard, 1-2 weeks expedited
• Targeted Panels - 2-3 weeks standard, 1 week expedited

Leading labs achieve TATs that are 30-50% faster than industry averages through systematic optimization.

Identifying Process Inefficiencies

Once you have data, use it to identify specific inefficiencies.

Value Stream Mapping

Map your entire workflow:

• Document every step from sample receipt to delivery
• Measure time for each step
• Identify value-added vs. non-value-added activities
• Calculate process efficiency (value-added time / total time)

Root Cause Analysis

For each bottleneck, identify root causes:

• Equipment issues - Downtime, capacity constraints, maintenance needs
• Process issues - Inefficient workflows, unnecessary steps, poor batching
• People issues - Training gaps, workload imbalances, communication problems
• System issues - LIMS limitations, integration problems, data flow issues

Waste Identification

Identify and eliminate waste:

• Waiting - Samples waiting for processing, results waiting for review
• Over-processing - Unnecessary QC steps, redundant validations
• Transportation - Moving samples unnecessarily, inefficient routing
• Inventory - Excess reagent stock, sample backlog
• Motion - Unnecessary staff movement, inefficient layouts
• Defects - Rework due to errors, failed runs, quality issues
