The most sensitive, accurate and reliable pregnancy test is a blood test for the presence of beta HCG (human chorionic gonadotropin), often just called beta. The HCG is produced by the embryo, and is the embryo's signal to the mother that pregnancy has occurred. Beta HCG levels vary according to the gestational age. In a non-pregnant woman, they are less than 10 mIU/ml. They are typically about 100 mIU/ml 14 days after ovulation in a healthy singleton pregnancy. They should double every 48 . In order to definitively know your hCG level it’s necessary to have blood tests. hCG levels can vary at different times of the day, from day to day and week to week. Remember – a one off hCG reading doesn’t provide much information; only what the level is at that specific point in time. It’s the pattern of readings and levels which gives a far more accurate indication of the status of . Human chorionic gonadotropin, or hCG, is a hormone produced during pregnancy in the cells of the placenta. Especially in early pregnancy, the amount of hCG present in the mother's body rises rapidly. In fact, it is the hormone detected in the urine by at-home pregnancy tests.. Normal hCG levels in pregnancy vary, but when women test above 25 mIU/mL, they’re pregnant. hCG levels can reach a height of nearly 300,000 mIU/mL by 9-12 weeks. Low levels do not necessarily mean an unhealthy pregnancy, but hCG levels can be rechecked every 48 to 72 hours.. hCG usually doubles every 48-72 hours very early in pregnancy and there is also no single "normal" hCG level during early pregnancy. Implantation occurs on average 9 days after ovulation (range 6-12 days) or about 5 days before a missed period. hCG levels are detected in the blood as early as 2-3 days,.
