Abstract:
A method is disclosed for monitoring local reactions, such as inflammatory responses, associated with injection sites. The method is performed using a temporary tattoo, which is transferred from a substrate to the skin of a subject, to measure the local reaction to an injection. A kit is also disclosed that can be used to perform the disclosed method. One example of the method includes transferring from the substrate to the subject's skin a temporary tattoo having a plurality of concentric rings and using the rings to measure the local reaction. For example, if the local reaction exceeds the boundary of the largest ring, the local reaction is considered clinically significant and additional medical interventions may be sought.
