What Sahara helps with
Sahara does not create or approve proxy access, and it cannot get around a decision Mount Sinai Health System makes. That stays with Mount Sinai Health System.
Once you can sign in to MyChart, Sahara is a free, read-only view of the record you are authorized to see, with general education from MedlinePlus for supported medications, labs and conditions, in English and Spanish. You connect through the MyChart authorization page and can disconnect at any time. Sahara does not give medical advice or interpret results.
