187 Patients Found New Answers Through Reanalysis of Genetic Testing: Jan 2026

Is a single genetic test result the end of the diagnostic journey?
At 3billion, we believe diagnosis is an ongoing process. That’s why we focus not only on the test itself, but on what comes after:
Reanalysis.

For all cases previously reported as Inconclusive or Negative,
3billion performs automated reanalysis through a continuous system.
Each month, dozens of reports are updated, revealing new diagnostic insights and possibilities.

Summary of Diagnostic Changes This Month

In January 2026, a total of 187 patients received updated reports through reanalysis. 

Why did the results change?

• 54%: Variant database updates
• 41%: Disease information updates
• 3%:  Additional clinical or phenotype data
• 2%: Segregation analysis

💡 This means that as clinical and scientific data evolve, the same patient data can lead to a different diagnosis over time.

How Does Automated Reanalysis Work?

3billion’s reanalysis system integrates updated variant and disease databases, along with internal interpretation models.
It also incorporates new phenotype and family history data submitted by clinicians.

Diagnosis doesn’t end with a single report.
It continues as the knowledge base grows— and 3billion’s automated reanalysis system ensures patients benefit from that progress.
