Why are TSI test observations made 18 to 24 hours after incubation?

TSI (triple sugar iron) test observations are made 18 to 24 hours after incubation because this time frame allows for the characteristic reactions to occur. The test is designed to differentiate between bacteria that can ferment glucose, lactose, and/or sucrose and produce acid and gas. Observing the reactions within this time frame ensures accurate interpretation of the test results.
