The practical question is under what conditions would the indicator be considered under- or overestimated?
For example, MDG Target 5 is: "Reduce by two-thirds, between 1990 and 2015, the under-five mortality rate, the obvious indicator is under-five mortality rate" – obviously the indicator is mortality, measured by rate of incidence of death [ 14].
During the clinical placement of the technologies under investigation, the indicators of patient acceptability/adverse outcomes: vomiting, crying, gagging, excessive arm/leg movements and other signs of distress [ 19] will be recorded by both the dental hygienist and dental nurse using an observational scale.
Consequently, many studies combine sensitivity with exposure or combine sensitivity with adaptive capacity depending upon the indicator under consideration.
Each indicator is obtained by solving an optimization problem aimed at maximizing a statistical distance (namely the Kullback divergence) between the distribution of the indicator under different faulty and fault free working modes.

Another problem encountered with fluorescent dyes is photodamage of the indicator under constant illumination generating less fluorescent species and a decreasing signal over time.
The oral fluid collection pad was placed under the tongue until the indicator turned blue or for five minutes in cases where the indicator did not turn blue within a shorter time.
The saliva collection pad was placed under the tongue until the indicator turned blue, or until 5 min has passed and transferred to a capped vial labelled with a bar code label corresponding to the bar code of the questionnaire.
