Hi i would like to know what this test means? is my wife pregnant or not? choriogonadotropin intact+beta subunit a 631 iu/l

Depends on why test: Numbers are just numbers, with little meaning unless one knows the whole picture. A woman who is trying to see she is pregnant, and has a pregnancy test result above 25 IU/L (mIU/mL), is presumed pregnant. That means she tested because she missed her regular period, or she is having early pregnancy symptoms 2-3 weeks after sex. As always, life's interpretations depend on the big picture.
