One million patients help redefine normal blood test values
NCT ID NCT07433777
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study is analyzing data from up to one million people across Italy to establish better reference intervals for complete blood count tests. Instead of recruiting healthy volunteers, researchers will use routine lab results from electronic health records. The goal is to create more accurate, age- and sex-specific ranges that could improve how doctors interpret lab results.

- What this could lead to
- If successful, this could lead to more accurate and personalized reference ranges for blood tests, improving diagnosis across different ages and regions.
- What could go wrong
- This is an observational study using existing data, so it won't test a new treatment. The results may not apply to other countries or populations.
