Welcome to the forum :)
As far as I know the Research lab collects data from four eBay sites - eBay.com, eBay.uk, eBay.ca and eBay.au
After you send your keyword to the labs a report will be generated which includes data from all four eBay sites mentioned above.
To view the results simply click on the gray arrow beside your keyword and a drop down menu of the different reports will be available for you.
For example, you can see the competition and demand for all four eBay sites.
Hope this helps
