I was automatically tested for it, plus 100 other things at my 12 week appointment with all of my other blood work. I didn't ask for this test and was a bit taken back when they told me i was being tested for it. I was like OMG i don't have HIV and the Dr. laughed and said it was standard. But anyways, for the clinic i was going to, it was just one of many standard blood tests they gave me while pregnant so i would assume this is common practice.
