Frequently Asked Questions

What is the difference between an EHR and a patient portal?
An EHR is your digital medical record kept by providers. A patient portal is the secure online tool you use to access parts of your EHR, like test results and messages.
How can I access my health data?
Most providers offer a patient portal. You can also request copies of your records directly from your provider's office. Federal law gives you the right to access your health records.
Are wearables like smartwatches accurate?
Wearables vary in accuracy. They are good for tracking trends but not for medical diagnosis. Always discuss important health decisions with your doctor.
