Good: Your doctor should have explained that levels less than 10 are considered negative, at most labs.

Speak with your MD: Your b-hcg has declined dramatically, however, it has plateaued and is now rising. Are the recent b-hcg values elevated? Normal values are usually less than 2, but normal values may vary by the laboratory doing the test. Your prognosis should be excellent, though you may need to be treated with a chemotherapy regimen called ema/co. Please speak with your oncologist.

Molar pregnancy: Very good. You most likely need to be placed on birth control pills to keep pituitary production of bhcg from interfering with the blood test.
