HCG appears in the blood and urine of pregnant women as early as 10 days after conception. Quantitative HCG measurement helps determine the exact age of the fetus.
How soon can a quantitative hCG test detect pregnancy?
hCG can first be detected in a blood sample about 11 days after conception. Levels of hCG continue to double every 48 to 72 hours. They reach their peak around 8 to 11 weeks after conception.
How soon will a hCG test show positive?
Detection of hCG depends on the timing of implantation, so hCG can normally be detected in the blood between nine and 16 days after ovulation. Urine hCG can be detected about two to three days after blood hCG can first be seen.
Can hCG blood test detect 1 week pregnancy?
To test your blood for hCG, a simple blood sample is taken from one of your veins, usually in the arm, through a procedure called a venipuncture. HCG is a hormone secreted in pregnancy and detectable beginning a week to two weeks (or more) after conception, depending on the test.
What should hCG be at 4 weeks 3 days?
Typical hCG Results
3 weeks: 5 – 50 mIU/ml. 4 weeks: 5 – 426 mIU/ml. 5 weeks: 18 – 7,340 mIU/ml. 6 weeks: 1,080 – 56,500 mIU/ml.
What was your hCG level at 4 weeks?
At 4 weeks pregnant, your hCG levels can range from about 10 to 708 mIU/mL.
How quickly does hCG rise after implantation?
The levels of hCG rise rapidly in the earliest days of pregnancy and can be detected around eight days after the estimated day of conception in the blood by the most sensitive laboratory methods. Home pregnancy tests can detect it a few days later in urine depending on their sensitivity.
What should be the hCG level at 2 weeks pregnant?
The placenta starts to produce HCG once the sperm fertilises the egg, therefore it usually takes around two weeks for the levels to be high enough to be detected by a pregnancy test. Average hCG levels: Less than 10 U/L in non-pregnant women. 10 to 25 U/L for a ‘borderline’ pregnancy result.
Does late implantation affect hCG levels?
By the end of the first week following hCG detection, late implanters showed lower mean levels of hCG. Daily hCG trajectories by time elapsed between ovulation and first hCG detection (“time to implantation”) for 142 clinical pregnancies during the first week of detection.
How do you read a quantitative hCG test?
An hCG level of less than 5 mIU/mL is considered negative for pregnancy, and anything above 25 mIU/mL is considered positive for 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.
What is quantitative pregnancy?
Quantitative hCG testing measures the actual amount of hCG present in the blood. It may be ordered to help diagnose an ectopic pregnancy, to help diagnose and monitor a pregnancy that may be failing, and or to monitor a woman after a miscarriage.

What is considered a high hCG level at 5 weeks?
hCG levels at 5 weeks should be about 19 to 7,340 mIU/mL. As you can see, it’s a big increase from week 4! And it just keeps getting bigger. hCG levels at 6 weeks will increase to around 1,080 to 56,500 mIU/mL.
