Here are the ranges for the lab that we use in our practice. These will not necessarily be exactly the same ar your practitioner's lab as values vary slightly by lab.

Weeks after conception and hCG levels:

0-1 week: 0-50 IU/L
1-2 weeks: 40 - 300
3-4: 500 - 6,000
1-2 months: 5,000 - 200,000
2-3 months: 10,000 - 100,000
2nd trimester: 3,000 - 50,000
3rd trimester: 1,000 - 50,000
Non-pregnant females: <5.0
Postmenopausal: <9.5

As you can see, there is great variation in hCG levels. It isn't the absolute value that matters in these results, but the change in values. In a viable embryo, doubling generally takes place every 36 hours.
