Paternity Testing With Blood

How does paternity testing process with blood work?

Performing a paternity test using blood will depend on whether you are using your result for legal or peace of mind purposes. Using blood samples like blood stains from a band-aid, tampon, or bloody tissue cannot be used for legal purposes. If you require a paternity testing result for any legal use. A blood card or blood draw is the commonly accepting sample collecting options available. There may be an exception to the rule if another type of blood DNA sample is available and a judge deems that specific blood sample acceptable.

Is a blood DNA test more accurate than a swab DNA test?

The testing accuracy for blood DNA testing vs buccal swab DNA testing is about the same. They have a 99% success rate of conclusiveness.

Does the alleged father and child have to submit blood samples when performing paternity tests?

Normally, unless there is a specific circumstance that either the alleged biological father

or the child is unable to use a blood draw or blood card method. Testing two different samples is an option that can be done but all parties involved with the paternity testing process normally have their samples collected using the same method.

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.
