Yeah! Me neither until my sister mentioned it. Don't know what we'll use in its place, its such a helpful test. (This was the test that first clued in the doctors of the woman who wrote Brain on Fire that she wasn't schizophrenic but was having some other organic brain disease, which turned out to be NMDA receptor antibodies causing psychosis in her case).
I LOVE genetics - it's what first interested me in biology in high school. In another life I'd be a genetic counselor or one of those genetic genealogy people who catch criminals. (If you haven't watched The Genetic Detective show on ABC you MUST watch it. ) It's truly amazing what we can do now.
