WebSep 5, 2024 · What is a 95% reference interval? The 95% interval, is often estimated by assuming a normal distribution of the measured parameter, in which case it can be defined as the interval limited by 1.96 (often rounded up to 2) population standard deviations from either side of the population mean (also called the expected value). WebThe II compares the biological variation of an analyte within an individual to that between all individuals. The index predicts the usefulness of a reference interval. Most BTM have marked individuality (low II) meaning that the biological variation within an individual is much smaller than that between all individuals (Table 4). In such cases ...
