The amount of time between your request for your medical information and the approval of your access to that information is completely dependent on the medical organization from which you are attempting to gain access to your information.
You can check the status of your connection by clicking "My Account" in the top right corner of the page, then selecting “My Connections” from the drop-down list.
If nothing is in this list (see image below), please consult this article if you need assistance in adding a connection to a medical organization.
