Inaccurate diagnoses |
Inaccurate diagnostic kits may lead to individuals undertaking harmful behaviours, either as the result of a false positive or a false negative [15, 16]. |
Inaccurate understanding |
Individuals may misunderstand test results or accuracy of those results [17, 18]. |
Insufficient pre-test support structures |
By enabling individuals to diagnose themselves away from health care settings, self-testing kits may mean individuals undertake test without the pre-test counselling by health care professionals and/or counselling services, potentially leading to psychological harm [14, 19, 20]. |
Insufficient post-test support structures |
By enabling individuals to diagnose themselves away from clinical settings, self-testing kits may mean individuals receive test results without the support of health care professionals and/or counselling services [20, 26]. |
Deter necessary service interactions |
By enabling self-diagnosis, self-tests may lead to individuals consulting clinicians about their health less frequently, meaning conditions other than those being tested for are left undiagnosed for longer. |
Undermining obligations to others |
By performing tests in private, individuals may be less likely to inform others of diagnosis (e.g. contact tracing) [26]. |
Undermining relationship to others |
By supporting an overly individualistic model of health care, self-testing may be inappropriate for health care, which tends to privilege close relationships and human interdependence [17]. |
Threat of testing becoming mandatory |
Danger of self-testing being made obligatory, either legally or through social pressure (e.g. during an epidemic) thereby infringing individuals’ right ‘not to know’ [14, 59]. |
Privacy breaches through theft of kit |
Individuals’ right to privacy may be infringed through theft and/or misuse of the diagnostic kit [26]. |
Privacy breaches through use of test data |
Where test data is stored and analysed remotely, individuals’ right to privacy may be infringed through misuse of data (including onward sale to third parties). |
Cost and unequal access |
If the cost of the diagnostic technology is sufficiently high, distribution based on ability to pay may exacerbate existing health inequalities [14, 20]. |
