There are trade-offs to the increased capacity to test and the rapid turn-around of the results: the accuracy of the tests in the field drops. For testing to be safe and effective the quality of instructions and information available is as important as technical validation or accuracy. It is vital that people understand how to do the test, and that the supporting material is clear and legible.
What we are doing
We are co-designing instructions that ensure confidence and accuracy, hence optimising the use of LFT in mass community testing.
We are using information design methods, and following traditional information design methodology (discovery, transforming, making), and evaluating the effectiveness of the design prototypes. Initial pilot work looked at blood testing, and we are now building on it to tackle swab testing in community mass testing context.
We are evaluating the usability of instructions and device through remote participant observation, questionnaires, seeking qualitative feedback sessions with end-users to gather impressions about prototypes.
