How reliable are prenatal paternity tests?

I have no doubts on who the father is, but because we haven’t been dating long and aren’t married, I know people will speculate once they find out.

My docs office said the Counsyl test doesn’t test paternity. And I was looking at other options online, are the prenatal blood tests reliable for determining paternity? Would like to have something definitive before we start telling people just In case a naysayer wants to spread any doubt. I’m 8 weeks right now

Also if you have a link or a test to recommend, I’d appreciate it

Update: His family doesn’t know about me so we are anticipating that when he says “Oh I’ve been dating a girl and she’s pregnant,” that will be a concern for them so we are trying to pre emptively address it because they are very traditional and will probably have issues when they find out.

UPDATE UPDATE: After calling around and finding out prenatal paternity is $1500 compared to $175 after baby is born, Dad seems fine waiting. He wasn’t going to ask me to do an amnio knowing it could risk the baby. So I guess if the family is adamant then they will just have to wait till the baby is born which I’m sure I’d need to do anyway at that point for documentation with the court and child support (if necessary)
