What is the beta-hCG level for pregnancy?
Standard hCG levels
| Pregnancy week | Standard hCG range |
|---|---|
| 6 weeks | 1,080–56,500 mIU/mL |
| 7–8 weeks | 7,650–229,000 mIU/mL |
| 9–12 weeks | 25,700–288,000 mIU/mL |
| 13–16 weeks | 13,300–254,000 mIU/mL |
What is hCG beta total pregnancy serum?
Ultrasonography and serial estimations of serum Beta Human Chorionic Gonadotropin (hCG) are used to detect or exclude an Ectopic Pregnancy (EP) in women presenting with vaginal bleeding or abdominal pain in the first trimester.
How early can serum hCG detect pregnancy?
How soon after conception can an hCG test be positive? The serum hCG test can be positive as early as 7-10 days following conception. However, in some pregnant women, the test is not positive 7-10 days after conception. This is because the time to implantation (and production of hCG) can be longer in some women.
What should my hCG level be during pregnancy?
An hCG level between 6 and 24 mIU/mL is considered a grey area, and you’ll likely need to be retested to see if your levels rise to confirm a pregnancy. The hCG hormone is measured in milli-international units per milliliter (mIU/mL).
When to take a blood hCG test to know if you are pregnant?
Blood hCG over 25 mIU/ml: You are pregnant! One single hCG reading is not enough to make a clear diagnosis. Several hCG tests 2 or more days apart give a more accurate assessment of the situation. The blood hCG levels should not be used to date a pregnancy since these numbers can vary so widely.
When do beta hCG levels go down during pregnancy?
Beta hCG levels usually double about every 2 days for the first four weeks of pregnancy. As pregnancy progresses the doubling time becomes longer. By 6 to 7 weeks beta hCG levels may take as long as 3 1/2 days to double. hCG normally reaches a peak level at about 8 to 10 weeks and then declines for the remainder of the pregnancy.
How long does it take for hCG to double in early pregnancy?
Between 1,200 and 6,000 mIU/ml serum levels in early pregnancy, the hCG usually takes 72-96 hours to double. Above 6,000 mIU/ml, the hCG often takes over four or more days to double. The gestational sac is usually seen on a transvaginal ultrasound once the hCG levels have reached between 1,000 – 2,000mIU/ml.
