I am wondering about my child because my wife and I have had a rocky past,I don't really want her to know,is it possible to take a home paternity test without her signature,I have read somewhere that both parents have to fill out a form,is there anyway around this?is it true?

I just took a home paternity test and it says I am NOT the father. I do not trust this result and I will be taking a real dna test soon, but besides these home tests being unreliable can breastmilk affect the results of a dna test? Somebody here on yahoo with alot of experience says they did but I can't find anything anywhere else that says breastmilk affects dna results when using a swab. Anyone know?

Can anyone recommend a good home paternity test kit.
