After the fertilized egg implants, the growing placenta starts releasing hCG into your blood. Some hCG also gets passed in your urine. HCG can be found in the blood before the first missed menstrual period. This can be as early as 6 days after the egg implants.
How long does it take for hCG to show up?
For many of these tests, hCG can be detected in your urine about 10 days after conception. However, taking it after your missed period reduces the chance of getting a false-negative. There are a few things to keep in mind when you take a home pregnancy tests, including: Using your first morning urine when possible.
Where is hCG produced early in pregnancy?
Human chorionic gonadotropin is a hormone produced primarily by syncytiotrophoblastic cells of the placenta during pregnancy. The hormone stimulates the corpus luteum to produce progesterone to maintain the pregnancy. Smaller amounts of hCG are also produced in the pituitary gland, the liver, and the colon.
What week of pregnancy does hCG peak?
Typically, the hCG levels will double every 72 hours. The level will reach its peak in the first 8-11 weeks of pregnancy and then will decline and level off for the remainder of the pregnancy.
How long after implantation does hCG rise?
Different Types of Pregnancy Tests and How Soon to Take One
The levels of hCG doubles every 48 hours after implantation. So, if a woman experiences implantation bleeding, then it is better to wait for four to five before taking a blood test for accurate results.

What is the hCG level at 1 week?
Average hCG levels: Less than 10 U/L in non-pregnant women. 10 to 25 U/L for a ‘borderline’ pregnancy result. more than 25 U/L for a postive result.
What is borderline pregnancy?
A borderline result is generated by some assays when the hCG level is between 5 and 25 mIU/mL. Samples reported as borderline are considered indeterminate, and clinicians should request a repeat test within 48 to 72 hours or obtain a quantitative serum hCG.
Can you be 6 weeks pregnant and test negative?
There are frequent cases where a woman has been six weeks pregnant with a negative pregnancy test and had a healthy baby about 34 weeks later. If you’re sure of your dates but still testing negative at home, it might be worth visiting your gynecologist for a blood test or an early ultrasound.
At what hCG level will I miscarry?
Your levels will ultimately go back to 0 mIU/mL. In fact, anything less than 5 mIU/mL is “negative,” so effectively, 1 to 4 mIU/mL is also considered “zero” by doctors. If you have a miscarriage, the time it takes for your levels to go to zero varies based on how high your levels were at time of miscarriage.
Is hCG different for each pregnancy?
Levels of hCG can differ between individuals and between different pregnancies in the same person. Some people may naturally have lower levels of hCG than others. Taking measurements of levels throughout the pregnancy can indicate if the pregnancy is developing as expected.
What should hCG be at 6 weeks?
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|
