What it measures
This shows whether your blood type is A, B, AB or O. The positive or negative part of your blood type, called Rh type, is checked by a separate test.
Why it matters for women
Blood type is part of routine early prenatal testing, along with Rh type and an antibody screen. If you’re type O and your baby is A or B, your baby may be more likely to have newborn jaundice, a yellowing of the skin that’s usually mild.
You might check it if…
- you’re pregnant or planning a pregnancy
- you’ve never learned your blood type
What your result may mean
High Blood type (ABO): what it may mean
ABO blood type can't be high or low, because the result is a category (A, B, AB or O) and not an amount. Your group can matter for matching blood if you ever need a transfusion. In pregnancy, a clinician may look at it along with Rh type and an antibody screen. If you're type O and your baby is A or B, your baby may be more prone to newborn jaundice (ABO incompatibility), a yellowing of the skin that can be mild. A meal, exercise or a passing illness can't change your blood type.
Low Blood type (ABO): what it may mean
There's no such thing as a low ABO result, because blood type can't be measured on a scale like most lab values. The report can only name one of four groups: A, B, AB or O. The plus or minus you may see after your blood type is your Rh type, and that can come from a separate test. No group can be called better or worse on this test, and each one can be perfectly healthy. If you're pregnant or may need a transfusion, your clinician can explain what your group may mean for your care.
