Cred ca in cazul acesta sunt corecte mai multe variante. Probabil si cele pe care le-ai gasit tu se folosesc in paralel. Cred ca in cele din urma toate inseamna acelasi lucru. Mie cel mai bine imi suna "valoarea-prag".
Definitia in engleza se potriveste cu definitia in romana: What does “Cut-off level” mean?
Essentially, it means separating the positives from the negatives. In drug and alcohol testing, a cut-off level is a level at which the concentration of a substance in your breath, urine, or saliva, indicates a safety risk. So if your sample tests below the cut off level, your test has a negative result, and if your sample is equal to or above the cut-off, your test result is positive.
