Introduction: Reflective testing refers to the practice of adding on tests by laboratory staff. Little is known about what patients think of this practice.
Methods: We surveyed patients attending a general practice surgery and patients attending hospital outpatient clinics. We sought their views about the practice of adding on tests and about the information they received from requesting clinicians about their investigations.
Results: In both groups of patients, large majorities favoured an approach in which relevant additional tests are performed without consulting the requesting clinician or patient first. Most patients also felt that the requesting clinicians had provided a satisfactory explanation about what tests were to be performed and why.
Conclusion: Most patients are content to let NHS professionals add on relevant tests if this is felt to be in their interest.
