h CG can be detected through two different types of blood tests, or through a urine test.
A quantitative blood test measures the exact amount of h CG in the blood, and a qualitative h CG blood test simply detects the presence of h CG.
Development The earliest change that can be seen through a vaginal ultrasound at this time will be the “decidual reaction,” which is the thickening of the endometrium.
The endometrium lining thickens as the blastocyst burrows into it.
A blood test can be used to monitor h CG levels and progesterone levels.
A key fact to remember when choosing an ultrasound is that a transvaginal ultrasound can detect development in the uterus about a week earlier than a transabdominal ultrasound.h CG Hormones Once implantation occurs, the pregnancy hormone Human Chorionic Gonadotropin (h CG) will develop and begin to rise.This hormone will signal that you are pregnant on a pregnancy test.Development Around 5 weeks, the gestational sac is often the first thing that most transvaginal ultrasounds can detect.This is seen before a recognizable embryo can be seen.
