Add on tests
Add-on tests If extra tests are required which were not already on the request form received, these can be added by sending a new request form to the laboratory. This must have the relevant patient details, date, time and in the clinical details section state: “Add-on test”. The plastic bag should be closed and sealed to avoid confusion about a missing specimen. These tests will be processed as routine. We regret that the laboratory currently has no means of processing urgent add-on tests.
