A Note about Test Results in MyChart

You may see test results in MyChart before your provider.

We believe that sharing information builds trust and stronger relationships. Most test results are published immediately in MyChart, which means you may see results even before your provider.

  • Some results may be difficult to understand without explanation. It’s often best to discuss these together.
  • Every result is reviewed and you will be contacted with any results that are a cause for concern.
  • If you have an urgent concern, we encourage you to reach out to us.
