Imprecision-BV targets the test imprecision based on selected biological variation data and performance goals. Imprecision-BV is based on published "within-subject" biological variation data rather than consensus group performance. As such, Imprecision-BV is a tool to specify acceptable limits of imprecision. Use Imprecision-BV for any analyte with published limits.
Unity Real Time™ online uses the percent (%) biological variation specific for the performance goal. The software plots the ranges (decision limits) on a Levey‑Jennings type chart based on the selected performance goal and target value.
