What's this test for?

This test is ideal if you're RhD-negative and pregnant and need to find out your baby's RhD status. Knowing whether your baby is RhD-positive or RhD-negative helps determine whether you need Rh immune globulin (RhIG) treatment to prevent a condition called hemolytic disease of the fetus and newborn. It's a simple blood draw from you — no procedures on the baby are needed.

What's included in this test?

This test looks specifically for the RHD gene in tiny fragments of your baby's DNA that circulate in your bloodstream during pregnancy. Detecting this single genetic marker is enough to determine whether your baby is likely RhD-positive or RhD-negative, which is the key piece of information needed to guide Rh-related pregnancy care.

What happens after I get my results?

Your results will appear in your account along with a clear explanation of what a positive or negative fetal RhD result means for your pregnancy. If the result suggests your baby is RhD-negative, routine RhIG treatment may not be necessary, though this should always be weighed against your full pregnancy history and current guidelines. A standard lab report is available for download from your account, and because this is a one-time screening test tied to a specific pregnancy, retesting isn't typically needed unless advised for a future pregnancy. You can also revisit your report anytime using the trends feature to keep a record for your records.

How can I naturally support a healthy Rh-incompatible pregnancy?

While there's no natural way to change RhD status or prevent alloimmunization on your own, you can support a healthy pregnancy overall by keeping up with all recommended prenatal appointments and screenings. Eating a balanced, iron-rich diet and staying well hydrated supports healthy blood volume during pregnancy. Avoid missing any scheduled RhIG doses or follow-up testing, since timely treatment is the main way to prevent complications from Rh incompatibility.

When will I get my results?

Results are typically ready within about 7 days after your sample is collected. You'll receive a notification once your report is available in your account, so there's no need to call and check.

Who should consider this test?

This test is meant for pregnant people who have been identified as RhD-negative through routine blood typing. It's especially useful early in pregnancy to help guide decisions about whether Rh immune globulin treatment is needed later on. If you're unsure of your blood type, that should be confirmed first before considering this test.

What symptoms indicate I may need this test?

Rh incompatibility itself doesn't cause symptoms in the pregnant person, so this test isn't based on how you feel — it's based on your blood type. If you know you're RhD-negative, that fact alone is the reason to consider this test, regardless of symptoms. Your prenatal blood type screening is what typically triggers the need for this test.

What does a positive RHD result mean?

A positive result suggests your baby is likely RhD-positive, meaning there's a chance your immune system could react to your baby's blood cells if they mix during pregnancy or delivery. This is why RhIG treatment is often recommended in this situation, to prevent your body from forming antibodies against RhD-positive blood. Rare false positives can occur, so results are always considered alongside your overall pregnancy history.

What does a negative RHD result mean?

A negative result suggests your baby is likely RhD-negative, which means there's generally no risk of Rh alloimmunization for this pregnancy. In this case, routine RhIG treatment may not be needed, though this decision should still take your full clinical picture into account. Keep in mind that rare false negatives are possible due to genetic variations in the RHD gene.

How often should I retest?

This is typically a one-time test per pregnancy, since it's checking a fixed genetic trait of your current baby that won't change as the pregnancy progresses. If you become pregnant again in the future, a new test would be needed for that pregnancy. There's no benefit to repeating this test within the same pregnancy unless specifically advised.
