AFAIK a lone hcg result doesn't mean much. It is meant to double every 48 hours in a normal pregnancy..... sorry not much help!

THe important thing about HCG levels is the rate of increase. I think it's supposed to double every 48 hours. You can't tell anything much from one reading as everybody's baseline will be different.
Googling reveals this range:
3 weeks LMP 5 - 50 mIU/ml

4 weeks LMP 5 - 426 mIU/ml

5 weeks LMP 18 - 7,340 mIU/ml
6 weeks LMP 1,080 - 56,500 mIU/ml
7 - 8 weeks LMP 7, 650 - 229,000 mIU/ml
9 - 12 weeks LMP 25,700 - 288,000 mIU/ml
13 - 16 weeks LMP 13,300 - 254,000 mIU/ml
17 - 24 weeks LMP 4,060 - 165,400 mIU/ml
25 - 40 weeks LMP 3,640 - 117,000 mIU/ml
non pregnant 55-200 ng/ml

So as you can see BIG varietion is possible. Your level looks to be ok then for 5 weeks. Also - how sure of your dates are you? If you ovulated late you levels will be a bit lower as you aren't as far on as you thought. Are they reepeating the test?

here's a table.
as iWILLdothis says you need to have another test a couple of days later. Yours looks ok for 5 weeks but should double every 48 hours.

Good luck!

Good luck but don't get too stressed - I had hcg levels checked and although they increased they weren't happy as it wasn't quite as much as they'd have liked. I was so nervous at my scan at 7w thinking I'd lost a baby - turned out it is ID twins, so the levels are just an indicator and only really help if there's a big drop or it doesn't increase at all.
