In excreted urine, a reliable "marker" that a pregnancy has initiated is human chorionic gonadotropin (hCG).
<h3>
What is human chorionic gonadotropin?</h3>
- The trophoblast cells that surround a developing embryo.
- Eventually give rise to the placenta after implantation generate the hormone known as human chorionic gonadotropin, which helps women recognize pregnancy.
- Some pregnancy tests can detect the HCG's presence.
- The placenta secretes a hormone known as human chorionic gonadotropin throughout pregnancy (HCG).
- It tells the body to stop menstruation and makes the uterine lining thicker to support an embryo in development.
- After fertilization, HCG levels increase and stay elevated for another 10 weeks or more of pregnancy.
- As accurate as blood tests are urine testing.
- An individual is pregnant if their HCG level is high.
- An individual is not pregnant if a qualitative HCG test is negative.
- After a few days, a person should repeat the test if they still believe they are pregnant.
