In EETA, the cost of a test executed by sensor v i on sensor v j at a distance d from each other is computed as the sum of the energy spent by v j to send the output sequence of a self-test to v i, and by v i to receive such outcome.
This analysis must begin during design because the inclusion of a self-test to uncover some of the more pernicious faults can reduce the number of conventional tests that the rest of the strategy must include, but only if the manufacturer executes it during production and makes the effort to eliminate the redundant tests.
This might be explained by the test specific properties of a self-test to detect allergies; after a positive result, consumers can adjust their lifestyle, a consultation with a doctor is often not necessary.
The control condition consisted of a PDF file of one page which gave general information about self-testing (definition of a self-test and the types of self-tests that are available).
It is therefore essential that appropriate consumer information will be developed which is tailored to the general and test-specific determinants of a self-test, to provide a solid basis for informed choices about self-testing.
The same technique was used to distinguish those who believed that they may make use of a particular self test kit in the future from those who did not think that they would do so.
In the modeling study of Seattle MSM, a self-test with a window period that was shortened from 90 to 42 days led to decreased HIV prevalence if testing frequency also increased 1.6 fold.
Conservatively assuming that 10% of people have used a self-test, a sample of 4200 people will allow estimation of the prevalence of the use of self-tests with at least +/-1% precision and 95% confidence.
Preferences for HIVST attributes varied across country income setting, type of approach, having performed a self-test for HIV and type of specimen collection.
8 As an example of the dangers of a lack of formal counseling with self-testing, one case report describes a homeless Latino MSM who tested positive using a diverted rapid test kit from a self-testing trial.
Results from a general public survey indicated that 32% of people had ever bought a self-test kit, including pregnancy testing, of some kind [ 31].
