Poor health literacy and inappropriate test prescribing hamper the value of laboratory medicine. The disintermediation between test producers and interpreters may happen both in Point of Care Tests, where doctor mediation is provided, but laboratory expert supervision is not, and in Direct to Consumer Testing, where no medical mediation is provided at all. In these cases, the respect for patient's autonomy must not preclude the principles of non-maleficence (as an individual concern) and justice (as a societal concern), as wrong test interpretation can generate confusion, anxiety, inappropriate social behavior, useless medical examinations and considerable cost increase. Considering how different is patient ability to understand test results (if any) and handle any physical and psychological consequence, promoting health literacy and professional laboratory mediation become crucial professional priorities. The aims of this review are 1) to describe the importance of health literacy on laboratory test interpretation, medical advice and therapeutic compliance; 2) to discuss doctor-level, patient-level and caregiver-level educational interventions in light of the four principles of the value-based framework (personal value, technical value, allocative value and societal value). Based on these premises, the authors support the need to enhance health literacy in patients, help doctors improve the communication of results and validate commercial tests under the scrutiny of scientific community.

Background: This study examined the moderating role of e-health literacy (eHL) and patient-physician communication in the relationship between online diabetes information-seeking behavior (online DISB) and self-care practices.
