Reference intervals: verify, establish and transfer
Does the package-insert interval fit my population and my method? How do I build my own? Three calculators and a guide: verify with 20 individuals, establish with 120 or more (direct method) and estimate from the results the laboratory already has (indirect method). Content is in Spanish.
You need 20 results from reference individuals and the published interval; or 120 or more results per group; or an export from your system. Data are processed in your browser.
