In general, at 5 weeks gestation the range of normal values for hCG hormone is between 850-20800 mIU/ml.
The reason for such a wide range for normal hCG levels is that the hormone values are highly variable in each pregnancy. This also makes the particular value less important compared to the levels increasing at the expected rate (in an evolving pregnancy, hCG doubles every 2-3 days in the first trimester of pregnancy).
