Pregnancy can be detected with a pregnancy test 8 to 10 days.
Many hormones can be used to detect and diagnose pregnancy, the most commonly used being human chorionic gonadotropin, or HCG. since the alpha chain in the HCG molecule is structurally identical to the alpha chain of luteinizing hormone, the specific HCG-beta chain is usually measured to avoid cross-reactivity with luteinizing hormone. A pregnancy test to detect if you are pregnant is to detect the level of beta-HCG in your urine.
HCG mRNA can be detected in the follicular bulb on day 2 after fertilization. on day 8-10, when the embryo implants in the endometrium, HCG can be detected in the serum or urine of the pregnant woman.
The most commonly used test is the radioimmunoassay method, which is taken by pregnancy tests and can be positive 8 to 10 days after conception.
Those who have stopped menstruating, have early pregnancy reactions or have a positive pregnancy test should go to the hospital in time to confirm whether they are pregnant or not, so as to avoid accidents.
