I tested mine a couple months after he was born. I used the IdentaGene kit from CVS. It cost about 40 something in the store and the lab fee is about $129.
Funny thing is that when I was in the store I was looking for it but couldn't find it. I was told to ask this older black lady stocking shelves to help me. She was a sister somewhere about early to mid fifties. When we found the kit she was like...
Her: "So you can just do the test at home without anybody know or having to get any blood or anything?"
Me:"Yeah it's pretty convenient now."
Her:"You know, I should get lil <insert kids' nickname> such and such tested out. She 26 now"
Me:<stunned silence>
Her:"Yeah the one that's been raising her is a good man and been taking care of us all this time"
Me:<More silence>
Her"The one that I think might really be her daddy, he wasn't worth nothing, just good for making babies"
Me:<Silence> Purchased my sh*t and left.
In 3 about three minutes of us bonding looking for this item in this store this chick has pretty much told me that she let some old slu-foot n*gga get her pregnant and then placed the kid on another dude who had the means to take of her. For 26 f*cking years she has been lying to the child and this man and even the other dude.
