Cut-off Levels

Cut-off levels are specific thresholds set in testing or measurement processes to determine whether a result is considered positive or negative. They serve as decision points; for example, in medical tests, a certain level of a substance in the blood might indicate the presence of a condition. If the measured value exceeds the cut-off, the result is flagged for further attention; if below, it’s usually considered normal. These levels help standardize results and guide clinical or operational decisions, ensuring consistency and clarity in interpreting data across different situations.
