Human Chorionic Gonadotropin (hCG)  during pregnancy

By: Joe Hing Kwok Chu           按此看中文。

There is great variation in Human Chorionic Gonadotropin (hCG) levels during pregnancies.

Not pregnant: 5 mIU/ml

 8-10 weeks into pregnancy: 30,000-200,000 mIU/ml

Absolute value not important. Changes in value is important.

Human Chorionic Gonadotropin (hCG) should doubles about every two days during the first 10 weeks.

High levels of Human Chorionic Gonadotropin (hCG) may indicate: choriocarcinoma of the uterus, ectopic pregnancy (outside the uterus), Downs syndrome in fetus, hydatidiform mole of the uterus, normal pregnancy, or ovarian cancer.

Guideline to hCG levels during pregnancy:

hCG levels in weeks from LMP (last menstrual period) (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 females: <9.5 mIU/ml

絨毛膜促性腺激素 (hCG) 與懷孕關係

血清中絨毛膜促性腺激素 (hCG)：

没懷孕: 5 mIU/ml

 懷孕 8-10 周: 30,000-200,000 mIU/ml

绝對值是不重要。值数變化才是重要。每两天絨毛膜促性腺激素 (HCG)的數值應作雙倍上升。

• 最後一次月經來臨之3 周後:  ----- 5 - 50 mIU/ml
• 最後一次月經來臨之:4 周後   ----- 5 - 426 mIU/ml
• 最後一次月經來臨之: 5 周後   -----18 - 7,340 mIU/ml
• 最後一次月經來臨之:6 周後    -----1,080 - 56,500 mIU/ml
• 最後一次月經來臨之7 - 8 周後-----7, 650 - 229,000 mIU/ml
• 最後一次月經來臨之9 - 12 周後:-- 25,700 - 288,000 mIU/ml
• 最後一次月經來臨之13 - 16 周後:17 - 24 周後 13,300 - 254,000 mIU/ml
• 最後一次月經來臨之17 - 24 周後:  4,060 - 165,400 mIU/ml
• 最後一次月經來臨之:25 - 40 周後  3,640 - 117,000 mIU/ml
• 没懷孕的婦女: <5.0 mIU/ml
• 绝經後的婦女: <9.5 mIU/ml
