An hCG level of less than 5mIU/ml is considered negative for pregnancy, and anything above 25mIU/ml is considered positive for pregnancy.About 85% of normal pregnancies will have the hCG level double every 48 - 72 hours. As you get further along into pregnancy and the hCG level gets higher, the time it takes to double can increase to about every 96 hours.A transvaginal ultrasound should be able to see at least a gestational sac once the hCG levels have reached between 1,000 - 2,000mIU/ml. Because levels can differentiate so much and conception dating can be wrong, a diagnosis should not be made by ultrasound findings until the level has reached at least 2,000.
hCG levels in weeks from LMP (gestational age)* :
* 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 females: <5.0 mIU/ml
* Postmenopausal: <9.5 mIU/ml

if your not pregnant obviously your blood would not show that you are. you will start out at a low number of hgc level in your blood and it will get higher as long as your still pregnant. if not the level of hormone will go down until it reaches 0.. also it goes up quickly. when i first found out i was pregnant i had a home test be positive and the test at dr say no - so they drew blood. my level was 14 . two days later it was 22
