Preparing For Your Lab Visit
For your convenience, Memorial Hermann Diagnostic Laboratory locations are walk-in labs -- no appointment is necessary. Wait times will vary depending on the number of patients, and are typically longer in the mornings.
Find a Memorial Hermann Diagnostic Laboratory location near you.
In preparation for your lab visit, please do the following:
- Get an order for a lab test from your healthcare provider. A diagnostic lab order can be printed or digital. If your healthcare provider doesn’t give you a printed lab order, please contact them prior to your lab visit to confirm that it was sent electronically.
- Confirm with your healthcare provider about any lab test preparation instructions. Ask if you need to fast (stop eating for a period of time), drink more or less water than usual and/or avoid certain medications before the test.
When your lab test results are available, you can view them at EverydayWell.com.
