I want to find out who my baby's father is without a DNA test. Can I use the old fashioned blood type testing?

In brief: Too vague

Blood type testing can certainly exclude a designated person if their blood type is incompatible with that of the child.
For example, a dad who is ab would not have a kid that was an o. But narrowing down & proving someone is by this means is unlikely.There are some companies that offer dna tests for this purpose & some states will require this method to identify dads for child support disputes.

In summary, you can exclude a father, but not prove fatherhood.
