Members of CVS/Aetna will receive one of two text messages or receive no text message at all. In the available for members condition, participants will receive a text message that says, "Two common kidney tests have been made available for members. By taking them, you could stay ahead of any problems and keep enjoying life. Schedule a doctor visit today to ask about them." In the Checked Health condition, the message will say, "Have you checked your kidney health recently? By taking two common kidney tests, members can stay ahead of any problems and keep enjoying life. Schedule a doctor visit today to ask about them." There will also be a group of members that do not receive a text message at all.

The investigators will examine the proportion of participants that book an appointment, proportion of new diagnoses for CKD, creatinine tests and/or albuminuria tests, proportion of participants that looked for more information after receiving the text message. The investigators will examine these metrics 6 months after all of the text messages have gone out ~8,637. The investigators will examine difference in conditions between the metrics listed above in the DV section. The investigators will compare the two conditions to each other, as well as to the group who does not receive a text message. The investigators will conduct a series of chi square tests/logistic regressions to examine the differences.
