Reference ranges from routine lab data in Italy

Reference Intervals With Indirect Methods in Italy

Observational Centro di Riferimento Oncologico - Aviano · NCT07433777

This project tests whether routine clinical lab records can be used to create reference ranges for lab tests so doctors can interpret patient results without recruiting healthy volunteers.

What this trial studies

The study uses existing laboratory and electronic health record data from multiple Italian hospitals to derive reference intervals using indirect statistical methods. Researchers apply algorithms and data-cleaning procedures to isolate likely healthy results from routine clinical datasets and calculate age- and sex-specific reference limits. They compare derived intervals across centers and demographic groups to check consistency and potential biases. This observational approach aims to reduce costs and selection bias associated with recruiting healthy volunteers for direct reference interval studies.

Who should consider this trial

Good fit: The project uses routine lab results from patients whose tests were performed at participating Italian hospitals and laboratories.

Not a fit: People who do not have lab tests recorded at the participating centers or whose data are excluded for privacy or quality reasons would not be part of this work and would not directly benefit.

Why it matters

Potential benefit: If successful, this approach could provide accurate, up-to-date reference ranges for many lab tests while lowering costs and including broader patient populations.

How similar studies have performed: Indirect methods have been applied in other countries and shown promising results for many analytes, though performance varies by test and population.
