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
Many people had it in the past without symptoms.
Why it's done
- Pregnancy with a possible exposure or flu-like illness
- Weakened immune system
Getting ready and what happens
- None.
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.
What the results mean
Recent infection in pregnancy
A specialist can discuss treatment and testing 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.
