Hi Lits, a huge congrats on your pregnancy, wishing you a happy and healthy 9 months - your levels are looking great so far. I work in a lab where they do the hcg levels and the only reason the report says about the method is cos hcg is used for monitoring tumours as well as pg and for that, the same method has to be used all along. So as far as you are concerned, all is looking great so far - GOOD LUCK hun
