The cost of a pregnancy blood test for progesterone and HVG is about 150 yuan, which may vary slightly between different levels or hospitals in different regions. Women are not required to have an empty stomach before having their blood drawn. Generally, simply observing the condition of the gestational sac within the gynecological ultrasound in early pregnancy is not able to determine the growth and development of the early embryo. In order to assist in the diagnosis of embryonic growth and development in the uterine cavity, it is necessary to dynamically observe the levels of progesterone and HCG. Progesterone levels between 15-25 ng/ml are normal in early pregnancy, while HCG levels increase doubly with the number of days of menopause. If the HCG and progesterone levels are low, it is easy for a woman to have an aura of miscarriage, such as lower abdominal pain, a small amount of vaginal bleeding, or even an inevitable miscarriage.
