Abstract The term “direct-to-consumer testing” (DTCT) describes all kinds of laboratory testing performed without the inclusion of a laboratory professional. It is thus performed in a gray zone between healthcare and consumers. The high volume of DTCT data as well as the ostensible feasibility of long-term data storage challenge medical professionals and consumers. No standards have been developed so far for the long-term storage of DTCT data. Unlike tests used in traditional laboratory medicine, many DTCT tests lack medical usefulness. This article describes the current concepts of DTCT and gives recommendations for the long-term data storage of DTCT data depending on the purpose of DTCT, the volume of data obtained and the possible medical implications of the test results.
