How To Prepare

It is important to know exactly when you took the last dose of the medicine for which you are being tested. Testing is usually done right before you take another dose. Ask your health professional for instructions about the timing of the test.

Tell your health professional about all the prescription and nonprescription medicines you are taking and any drugs (such as alcohol, marijuana, or cocaine) you are using. Sometimes these can interfere with testing.
