HCG Levels in Pregnancy

--------------------------------------------------------------------------------
The following information is from Anne Frye (CPM)'s book: "Understanding Diagnostic Tests in the Childbearing Year" 6th edition

p. 108 "Normal hCG Levels in Early Pregnancy"
"HCG is detectable in the blood serum of approximately 5% of pregnant women by 8 days after conception, and in virtually all the rest by 11 days. HCG rises progressively from conception. Levels double on the average, every 30.9 hours until values reach 6500 mIU/ml (6,500 IU/L) at approximately the eighth week after the last menstrual period (LMP). After that the rate of rise becomes individualized, peaking between the 60th and 70th day (9 to 10 weeks) LMP. HCG decreases slightly between the 12th and 16th week post LMP, and then remains constant until birth. "


p. 111 "To Diagnose Pregnancy"
"A blood serum level of less than 5 mIU/ml (5 IU/L) can be considered negative and anything above 25 mIU/ml (25 IU/L) positive for pregnancy. If you are unsure, repeat the test in two days to see if there is an upward trend, which indicates pregnancy."

"Levels higher than expected for the weeks pregnant may be due to multiple gestation or inaccurate dates. ... Levels for normal pregnancy fall within the following wide ranges. You will note a discrepancy between the ranges of normal in the two tables below. The actual level can vary widely, and is not as significant as the amount and rate of rise, particularly before 10 weeks."


p. 112

PREGNANCY STATUS SERUM hCG LEVELS

from conception from LMP (mIU/ML or IU/L)
7 days ~ 3 weeks ~ 0 to 5
14 days~ 28 days ~3 to 426
21 days ~35 days ~18 to 7,340
28 days ~42 days ~1080 to 56,500
35 - 42 days ~49 - 56 days~ 7,650 to 229,000
43 - 64 days ~57 - 78 days ~ 25,700 to 288,000
57 - 78 days~ 79 - 100 days ~ 13,300 to 253,000
17 - 24 weeks~ 2nd trimester ~ 4060 to 65,400
25 wks to term ~ 3rd trimester ~3640 to 117,000
After several days postpartum nonpregnant levels (<5)"


"Results in Twin Gestation"
"Quanitative serum hCG tests detect multiple pregnancy approximately 9 weeks earlier than ultrasound. One small study (Jovanovic, 1977) found hCG levels in 15 singleton and 9 twin pregnancies were as follows:

DAYS FROM LMP hCG in SINGLTON AVERAGE GESTATION RANGE hCG in AVERAGE TWIN GESTATION RANGE
28 ~ 64.7 ~9.4 to 120 ~ 64.7 ~ 9.5 to 120
33 ~ 450 ~300 - 600 ~ 1,500 ~ 200 to 1,800
36 ~ 1,500 ~ 1,200 - 1,800 ~19,200 ~2,400 to 36,000
40 ~ 3,600 ~2,400 - 4,800 ~58,344 ~ 8,700 to 108,000
45 ~36,000 ~12,000 - 60,000 ~126,000 ~72,000 to 180,000
70 ~120,000 ~96,000 - 144,000 ~ 414,000 ~348,000 to 480,000"

Answer 2

HCG levels can vary from person to person and pregnancy to pregnancy. Higher HCG levels could indicate twins. As long as your doctor isn't worried, then you shouldn't be either. You can ask the doctor to do an ultrasound around 7 weeks to see if you are having twins. Any earlier and you might not be able see anything inside the sac yet. Congratulations and best wishes.

Answer 3

Hi.:) Was your Dr. concerned?Could be normal for you ,could be that you are having twins.Think about it this way and it may help you worry less about numbers...A lot of women do not have qualitative blood tests done early in pregnancy and never know what their numbers were ,tests are good but unless you are having an obvious problem I think they cause a lot of worry if they seem higher or lower.If you have any concerns ask your Dr.He/she can probably give you a better answer.HTH's and Good Luck:)

You could be pregnant with twins!

Levels of hCG in pregnancy


Human Chorionic Ganadotropin (hCG) is a hormone that can be detected in the urine and blood of humans. This hormone increases during pregnancy so it is common to measure the rise in level using Home Pregnancy Tests ( or HPTs, which measure hCG levels in the urine) or a hCG Beta test (which measures hCG levels in the blood serum). The hCG Beta is much more sensitive then the Home Pregnancy Test and you can usually get a positive result much earlier with a blood test than with the HPTs.
Usually the reference values for hCG Beta are as follows:

Men: less than 5.0 mIU/ml - Normal

Women: Non -pregnant - less than 5.0 mIU/ml - Negative/normal

*Borderline - Between 5.0 to 25.0 mIU/ml (you could be pregnant)

*Positive - Higher than 25.0 mIU/ml

(*) These are values within the first week and few days after conception.
When you are pregnant the level of hCG increases and usually doubles every two to three days. It then reaches a maximum level by the second or third month of pregnancy, followed by a decrease occurring in the third trimester.

Here are typical hCG Beta values in pregnant women up to 22 days post-retrieval (DPR) or days post-ovulation (DPO).

DPR or DPO Amount of hCG in mIU/ml

10 5 - 50

12 10 - 100

14 20 - 200

16 40 - 400

18 70 - 800

20 140 - 1600

22 180 - 3200

Here are the hCG Beta values given by the number of weeks after ovulation:

after the 1st week and 2 days 5.0 to 50.0 mUI/ml

Between 1st and 2nd week 5.0 to 500.0 mUI/ml

Between 2nd and 3rd week 100.0 to 5,000.0 mUI/ml

Between 3rd and 4th week 500.0 to 10,000.0 mUI/ml

Between 4th and 5th week 1,000.0 to 50,000.0 mUI/ml

Between 5th and 6th week 10,000.0 to 100,000.0 mUI/ml

Between 6th and 8th week 15,000.0 to 200,000.0 mUI/ml

Between 8th and 12th week 10,000.0 to 100,000.0 mUI/ml

Note: The levels of hCG for pregnant women with twins or more are usually higher than the values above, which represent the typical values for just one baby.
