hCG stands for "Human Chorionic Gonadotropin," the pregnancy hormone, which is produced by the placenta and detected in the blood within a few days after implantation. When you test at home with a pregnancy test, you actually test for the presence of hCG in the urine. If hCG is present,...
For this reason, pregnancy tests are based on detecting hCG in blood or urine, since its presence is indicative of pregnancy. Specifically, pregnancy tests detect the beta subunit of this hormone, which is why they are also known as beta hCG tests. However, hCG hormone levels decrease to be...
it is known to double every 48-72 hours. Here, we are going to talk about how the HCG hormone can be detected, what is the normal level of the pregnancy hormone in the blood and many more. Also, we are going to take a look at the guideline to the levels of this hormone by ...

You can have a blood test if you want to definitively know your hCG levels since the levels vary at different times. However, one hCG test will tell you no more than the levels of that day or that point in time. What you are supposed to do is to ensure that you stay healthy and ...
In normal pregnancies, blood hCG levels increase rapidly after implantation, peaking around week 9–11. Due to this exponential increase, hCG levels are also used to diagnose abnormal conditions, such as ectopic and molar pregnancies, and to monitor miscarriages. Additionally, hCG level measurements ...
Tests can detect hCG hormone in blood about 11 days after pregnancy, after 12-14 days can detect hCG hormone in urine. During early pregnancy, in most women, hCG levels double every 48 to 72 hours until hCG reaches its peak in pregnancy at about 8-10 weeks...
FTS was based measurement of levels of pregnancy-associated plasma protein-A (PAPP-A) and free βHCG in the maternal blood as well as an ultrasound exam to measure the size of nuchal translucency (NT). The time at which patients referred was between 11 weeks of gestation and 13 weeks and...
