cut-off value

— For diagnostic or screening tests, the value used to divide continuous results into categories; typically positive and negative


cut-off point, cut point, threshold

Full explanation:

For diagnostic or screening tests that have continuous results (measured on a scale), cut-off values are the dividing points on measuring scales where the test results are divided into different categories; typically positive (indicating someone has the condition of interest), or negative (indicating someone does not have the condition of interest).


For example, the cut off for someone having a fever (measured on the Celsius scale) is 37.0 (the average human body temperature), a cut off below which treatment is not recommended for adults is 38.9, and a cut off below which a fever usually is not dangerous is 39.4.
