Good to knowOne result rarely tells the whole story. Your provider looks at your results together with your symptoms, exam, and other tests.
What the test is
Most people catch CMV without symptoms.
Why it's done
- Mono-like illness with a negative mono test
- Pregnancy concerns
- Newborns who fail a hearing test
- Transplant patients
Getting ready and what happens
- No preparation is needed.
How the test is done
- A health worker cleans the skin, puts a band around your arm, and draws blood from a vein with a small needle. It takes a few minutes.
- Newborns may have a saliva or urine test.
What the results mean
Recent infection in pregnancy
Talk with a specialist about testing and monitoring the baby.
Questions to ask your provider
- What do my results mean for me?
- Do I need to repeat this test or have other tests?
Risks
A blood draw is very safe. You may have slight pain or a small bruise where the needle went in.
