Can blood types determine paternity?

Unfortunately, using blood types to determine paternity is not an accurate or definitive way to prove an alleged father is the biological father of a child. What using blood types can do is prove an alleged father is not biologically related to a child. For example, if the assumed father has blood type – A and the child B positive it would not be possible for blood type A to produce a blood type B. Therefore, the alleged biological father could not be biologically related to the child.

How long does the DNA paternity test process take when using blood?
