, Reportable Ranges, and Test Unit Conversions
Reference range means the range of test values expected from 95% of fasting individuals presumed to be healthy. Reportable
range means the range of test values throughout which the measurement system’s results have been shown to be valid. The
following table contains the Reference Ranges (for adults) and Reportable Ranges applicable to the i-STAT System.
