There are many major medical facilities in New York City, there must be one that is in-network and capable of doing the test. I'm in CT and just haven't gotten to doing the search, yet, as I have run out of options in CT. (Don't go to Yale New Haven even if it is a big name. Just don't. Trust me.) There has got to be a place in NYC or on Long Island that is good. Keep looking.

What about Philadelphia? She must be within reach of Philly, also, yes? Maybe there is a place there?
