    I have AGS. My levels are .32; anything over .10 is positive so mine are nearly three times the…read moreminimum positive result. The Public Health nurse who called me said I should see an allergist and get a prescription for epi pens because AGS is weird and even with low levels I could have an anaphylactic reaction (and as it turns out the absolute gastrointestinal misery I went through that spurred me to get the testing *was* a form of anaphylactic reaction). Unfortunately I chose this place. Over $600 to be told the AGS levels on my blood test were "likely a false positive" and therefore no Epi was prescribed. Visit notes list several things that were not actually done and says I likely have "food intolerance", not an allergy. Completely disregarded the fact that AGS is a reaction to a SUGAR molecule while the limited scratch tests he did on me check reactions to PROTEINS (which is why they are NOT reliable for testing for AGS). Did NOT prescribe an Epi for me, so I just starved my way through a two-week camping trip for fear of potential reaction. My visit notes also suggest a "pork sausage challenge" at the office over 4 hours to rule out AGS. That's NOT the way AGS works. With AGS you can eat something one time and not react at all, and have the exact same thing two days later and have a bad reaction. It's a crap shoot. It's just plain dangerous to suggest to someone they're not AGS based on the fact that they don't react within a few hours to *one* in-office challenge. What happens when someone celebrates with a nice steak dinner because this doctor said they had a false positive, and they wake up in hospital or worse because *that's* when their body decided to react?? I also do NOT appreciate the complete lack of transparency with respect to pricing. Prices and fees should be clearly communicated BEFORE testing so the patient can make an informed decision as to whether to proceed. I feel like the over $600 I was charged for this one short visit with minor testing was a massive overcharge. I won't be going back.

    Dr. Vuong was laughing and reading City View with a nurse. I had a full-on panic attack while I was…read morein the waiting room . Waiting half naked to get poked 86 times and not feeling well. This to me was not professional at all. Dr Vaughn was not nice at all. And because of this I had a panic attack and needed a female nurse to be in the room. I would definitely not recommend go somewhere else. I should have.
