question about a blood work?

I had blood work done on Feb 4, 2009. On my screening sheet is stated:
GA @ U/S  BLOOD DRAW: 10 WEEKS(CRL)
Now if I go back 10 weeks does that mean 10 weeks ago i conceived or 10 weeks ago is how far along I am (lmp)?.

CRL refers to crown to rump which is measurement of the fetus from an ultrasound.  This means you conceived approximately 8 weeks earlier.
