I did one through child support years ago and that didn't take no more than 2 weeks. If you do the home test i guesstimate 3 to 4 weeks considering you have to mail it, wait for them to process, then mail results back to you.
Ok thanks do u know how long it takes to get back the results
Not sure about the home test but ive read online if done correctly its 99%. You pay 75$-150$ to send to i believe the same lab used for most dna test. Yes, you have to pay at doctors also. Only dna free is if you go through child support. They bill later to dad if child his but if not you have to pay.
