If you google "does Ravgen give results over the phone", apparently the answer is yes. Did the copy of the result they sent have a different answer than the one she was given over the phone?
You've asked questions about all of this a lot of times. What exactly has happened? Did you get a document from Ravgen that said you are the dad and you are still nervous? Did you call Ravgen yourself? Did you send them a copy of the document and ask if it is legitimate? Or, do you really not doubt it that much but are just nervous in general?
Brooklynguy, if you think the mother has created a false document, you might just call Ravgen. I can't learn online whether that information is privileged to the mom, but it wouldn't hurt to call and ask - at least that way you could clear your head of the questions as to whether she forged a document.
I'm not sure whether you have a right to the information, under possible HIPAA laws, but you won't be hurting anything by just putting in the call.
