is there a DNA kit I can buy with which I can check myself if my child is indeed mine? what can I do at home to find out the truth?
Go to a medical lab and have them handle this.
Yes, you can buy a home DNA kit, and send in samples from both you and your child. They send results in the mail. I would research which brand is best if that's what you want to do. Also, ask a doctor.
You can buy DNA kit for a paternity test. You can either buy the kit online at http://www.walgreens.com/store/c/identigene-dna-paternity-test-collection-kit/ID=prod4202920-product or ask from your local hospital if they sell. The kit is only for one supposed father, one child, and one mother (not obligatory).
Yes u can buy one at the store
