The most common approach has been to use diagnostic reference level (DRL), which is a 75th percentile of the mean doses for a sample of patients close to the standard size, typically 70 kg or, in some countries, 60–70 kg. The purpose in cases of DRL is to detect outliers (higher 25th percentile cases) from a sample.
