How can I know my blood type without a test?
Without drawing blood A person may be able to use a saliva sample to test for their blood type, as some people produce the characteristic antigens in their saliva.

Can O+ and O+ have a baby?
An A+ parent and an O+ parent can definitely have an O- child.
What would a child’s blood type be if the mother is type O and the father is type A?
A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter. This couple could have children of either blood type A (O from mother and A from father) or blood type B (O from mother and B from father).
What happens if one parent is O positive and the other O negative?
Children who inherit an A-O combination will be type A, but, remember, they could still pass that O gene off to their children. As a result, their child could wind up as type O if the other parent passes them an O-type gene, too. That last fact explains how O-positive parents can have O-negative kids.
Which blood type is most fertile?
A woman’s blood group could influence her chances of getting pregnant, scientists have found. Those with blood type O may struggle to conceive due to a lower egg count and poorer egg quality, while those with blood group A seem to be more fertile.
Can a child have a different blood type than both parents?
No it doesn’t. Neither of your parents has to have the same blood type as you. For example if one of your parents was AB+ and the other was O+, they could only have A and B kids. In other words, most likely none of their kids would share either parent’s blood type.
Can a child have type O blood if parents have A and B?
To be O, you usually need to get an O from both mom and dad. But an AB parent usually has an A and a B version, not an O. So they usually can’t have an O child. Except, of course, when they can.
Can blood type change?
Usually, you will have the same blood type all of your life. However, in some cases, the blood types have changed. This has been due to unusual circumstances, such as having a bone marrow transplant or getting certain types of cancers or infections. Not all of the changes in blood type are permanent.
How do I find out my child’s blood type?
Blood Inheritance The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be A. For instance, a parent with O blood with 2 O genes and a parent with A blood with 2 A genes will have an A blood type child with one A gene and one O gene.
Is my child’s blood type on their birth certificate?
If you don’t already know your blood type, finding record of it can be difficult – blood type isn’t on your birth certificate and is not typically listed in records from routine lab work. So, you may need to do a blood type test – and that’s actually quite simple.
