* 0-1 week: 0-50 mIU/ml
* 1-2 weeks: 40-300 mIU/ml
* 3-4 weeks: 500-6,000 mIU/ml
* 1-2 months: 5,000-200,000 mIU/ml
* 2-3 months: 10,000-100,000 mIU/ml
* 2nd trimester: 3,000-50,000 mIU/ml
* 3rd trimester: 1,000-50,000 mIU/ml
* Non-pregnant females: <5.0 mIU/ml
* Postmenopausal females: <9.5 mIU/ml
Abnormal Numbers
An HCG level that increases but is less than double the previous one is considered abnormal and suspicious of an ectopic pregnancy. Pregnancies that are both low in level and slow to rise are almost certain to fail. Singleton and
vanishing twin pregnancies have a wide range of acceptable HCG levels on a given day.
Greater-than-normal levels may indicate choriocarcinoma of the uterus, ectopic pregnancy, hydatidiform mole of the uterus, normal pregnancy, or ovarian cancer. Once you have had an ectopic prgnancy, you have an increased risk for another, so your HCG numbers may be monitored more carefully.
Lower-than-normal levels may indicate dead fetus, incomplete miscarriage, or threatened spontaneous abortion. Pregnancies destined to miscarry or to be ectopic (tubal) pregnancies tend to show lower levels (eventually), but often have normal levels initially. Some normal pregnancies will have quite low levels of HCG ò and deliver perfect babies.更多精彩文章及讨论，请光临枫下论坛 rolia.net
