If the Lab Vendor you are working with accepts electronic lab orders, simply click **eOrder** from the Lab Order Form - you do not need to fax the lab order to them. [Click here for more information about eOrdering](/articles/Electronic-Lab-Order-Form).
The workflow outlined in this article is an example of a way you can share test orders with testing facilities. Adjust the workflow (e.g. what you attach) as needed.
## Faxing orders to test vendors
After you create and sign any lab, radiology (imaging) or other test orders in Elation, you can electronically fax it to a test vendor via the Letter to Provider feature.
1. Locate the order that you’d like to send in your patient’s chart. Hover over the order, and click **Actions** -> **Provider Letter**.
1. In the **To** field, type the fax number of the vendor. If a search result appears in the [Provider Directory](/articles/Using-the-Provider-Directory) dropdown, click on the result to select an existing contact.
* If no results are found, press the **TAB** key on your keyboard and a dialogue window will appear prompting you to save the fax number to a new contact. Select **Organization**, type the name of the vendor, and click **Save**.
1. Type a subject and message to the vendor as needed.
2. Next, click **Select Chart Items to Attach**.
1. Check off the box for **Patient Demographics** and click **Attach Items**.
1. At the bottom of the letter, check off the box for **Also fax copies of attachments**.
2. Click **Sign & Send** to fax the order to the vendor.
To fax the order outside of Elation with your physical fax machine print the order by clicking **Actions** -> **Print** and then use your fax machine.
