Ontario Lab Results

What you need to know about your Ontario Lab Results in myUHN
  • You have the option to view your lab test results and pathology reports from other labs and hospitals in Ontario
  • These results are stored in the Ontario Laboratories Information System (OLIS)
  • Accessing these results, as well as your UHN results, gives you a more complete record of your care.
  • Since OLIS stores most Ontario lab results, the lab tests you have at UHN will show in both the UHN Results and Ontario Lab Results sections of myUHN.

  • Your results may change or be updated after you see them
  • You may see your results before you see your doctor at your next appointment
  • If you have questions, your health care team will explain your results
  • Your health care team will contact you if they need to see you sooner than your next appointment
Which labs provide information to OLIS, and what types of lab tests do they include?

The way my lab information appears in UHN Results and Ontario Lab Results is different. Why?

Since myUHN is getting these lab test results from different systems, some of the information you see will be different.

Your doctor is the best person to help you understand what your lab results mean. If you have questions about your lab test results, please contact the doctor who ordered the tests.

Does my health care team at UHN have access to my Ontario Lab Results?

The doctor who ordered your lab tests will receive your results directly from the lab. Others in your health care team, such as your family doctor, may have access to these results depending on where they are stored and the systems they use.

Do I get email notices when there are new Ontario Lab Results in myUHN?

No. myUHN is not alerted when there are new results from OLIS.

Who can I contact if I have questions about my Ontario Lab Results?

Please contact the doctor who ordered your tests if you have questions about the results.

What is a Consent Directive?

A Consent Directive gives you or your substitute decision maker, the option to restrict access to your personal health information in your electronic health record. If you do not want to share your health information with members of your health care team, you can restrict access by asking for a Consent Directive to be added to your record. This means when a health care provider tries to access your record, a notice will appear indicating your record is blocked.

Restricting access does not mean your record will be out of date. New information will continue to be added throughout your health care journey. You can unblock your record at any time. Once applied or removed, you will receive confirmation that your Consent Directive is in place, or has been lifted.

To add or remove a Consent Directive, visit the eHealth Ontario privacy website.
