It says the technology has improved but still, the angle of the view, position of limbs, and/or cord placement can fool the eye, so it's just not a good idea to put faith in the ultrasound for ascertaining sex.
It may be correct in most cases, but it is still a subjective test. I wouldn't paint walls or buy expensive DNA-specific baby items until I knew for sure.
In her 35 years as a practicing Ob/Gyn, she has never seen a mistake like this with one of her patients, said Dr. Laura Corio a gynecologist with Mt. Sinai Hospital in New York.
That's a weird statement on a number of levels.
Maybe her patients didn’t rely on ultrasound to determine the sex.
One of my friends asked the screener, “What is it?” and they guy said, “It’s a fish.”
