Every child has just one biological father. But sometimes you need a paternity test to identify the real father. And certain legal situations involving custody and child support require PROOF of fatherhood.
Later in life, an adult may become curious about his biological roots and need to verify his birth father. That's what happened to me. And that's how I got interested in DNA testing.
In all these cases a DNA test can uncover the truth.
I was adopted and eventually decided to search for my biological father.
Eventually, I found the man my deceased birth mother had named as my father. In my case, comparing our DNA proved that he was NOT my father.
One of the DNA tests used by adoptees to uncover unknown parents has turned out to be a great option for finding and confirming a child's biological father.
This test, called Family Finder, is great insurance against a negative result. That's because it provides important clues to the child's ancestry even if the tested man proves not to be the father. What's more, the cost is surprisingly low.

Many labs can do the standard test. Some are better than others. For some specific tips on choosing a lab see my page on DNA Testing Labs.
One leading lab that I can recommend without hesitation is this one:
You can confirm the father's identity before the baby is born with prenatal testing.
If the child's father is deceased--or just unwilling to be tested--you can sometimes acquire his DNA through forensic DNA testing.
DNA and The Law
DNA testing has had a huge impact on child custody laws.
In addition, women can use DNA testing to gain child support from deadbeat dads.
And men can use it to protect themselves against paternity fraud.
In some cases you can eliminate a potential father through a comparison of blood types. If you know all the blood types and get lucky, this might avoid the need for DNA testing.
