Ammonia

How To Prepare

Do not eat, drink anything other than water, or smoke for 8 hours before having an ammonia blood test.

Avoid strenuous exercise just prior to having this test.

Tell your doctor if you:

• Are taking any medicines. Many medicines can interfere with test results. Your doctor may instruct you to stop taking certain medicines for several days before having an ammonia test.
• Smoke or drink alcohol.

Talk to your doctor about any concerns you have regarding the need for the test, its risks, how it will be done, or what the results may mean. To help you understand the importance of this test, fill out the medical test information form (What is a PDF document?).
