I was just told that a Level I u/s, done in your OB's office, can be off by up to 2 lbs. either way.
But a Level II u/s, done at the high risk (etc.) office, is only ever off by 2 OUNCES.
Is this true? Because if so, zomg. I'm going to birth a toddler at this rate.
Re: Level II u/s more accurate than Level I for weight?
