I'm sure it can. For that, you take a few cells from the placenta, whose cells have the same genome as the embryo's. It's still a surgical encroachment into the mother's body, and I don't necessarily think it's worth it, yet it can be done.
But I'm not sure if that's important for the conversation Clary's son will have with his (ex-) girlfriend. If I were him, my message to her would be something like this: "If it's my child, it has my support, just as morality and the law demand it. You may or may not have my support, depending on a lot of things. If this is not my child, on the other hand, neither of you has my support." I don't see how pre-natal diagnostics are strictly necessary to communicate this or to go through with it.
