Human chorionic gonadotropin hCG is a hormone normally produced by the placenta. If you are pregnant, you can detect it in your urine. After you conceive when the sperm fertilises the egg , the developing placenta begins to produce and release hCG. It takes about 2 weeks for your hCG levels to be high enough to be detected in your urine using a home pregnancy test. A positive home test result is almost certainly correct, but a negative result is less reliable.
Human Chorionic Gonadotropin (hCG) Blood Test
Pregnancy begins with the fertilization of the ovum and subsequent implantation into the uterine wall. The duration of pregnancy is counted in weeks of gestation from the first day of the last menstrual period and on average lasts 40 weeks. Presumptive signs of pregnancy include amenorrhea , nausea and vomiting, and breast enlargement and tenderness.
A pregnancy test attempts to determine whether or not a female is pregnant. The most common tests use markers found in blood and urine , specifically one called human chorionic gonadotropin hCG. Identified in the early 20th century, hCG rises quickly in the first few weeks of pregnancy, peaking at 10 weeks. Urine tests will typically show positive around four weeks after the last menstrual period LMP and are best done in the morning as hCG levels are then highest. Obstetric ultrasonography may also be used to detect pregnancy.
