[|Human|] Hi there, I need to determine whether or not my brother girlfriend is pregnant with his baby.  On the date of the test her ChatDoctor levels were 800 and informed him that she was three weeks.  I have read up and according to some sites the ChatDoctor levels on three weeks sould be 0-50.  PLEASE assist
[|AI|]  HI, I understand your concern.  I feel there is confusion in counting the weeks.  - Chat Doctor at 3 weeks from is 5-50 flu/ml - Chat Doctor at 3 weeks pregnancy (about 5 weeks form LMP) is 18-7240mlU/ml.  However It's not possible to determine pregnancy duration/ father of the baby ... by Chat Doctor, as the levels vary with pregnancy & the person.  * So to know the duration of pregnancy by USG in early months can help in calculating possible paternity vaguely( by comparing with the day of sex) - Paternity can be confirmed only by chromosomal analysis.  Thanks.
