That just sounds like a test of her hCG levels which really doesn't tell us anything does it?
Actually, it says a lot if you're the interested couple or a doctor.
If she has low levels of hCG, it might indicate a miscalculation of the date of her pregnancy, a miscarriage, a blighted ovum or an ectopic pregancy.
If she had high levels of hCG, it might mean that there was a miscalculation of the date of her pregnancy dating, a molar pregnancy or a miscarriage.
