9 week sonogram12/20/2023 Instead of the hCG, after 6 weeks or an hCG above 6,000 mIU/cc, the health of the pregnancy can best be confirmed with a sonogram to confirm the presence of a fetal heartbeat. In general, after 6-7 weeks the best indication of a healthy pregnancy is a good fetal heartbeat. Blood hCG levels are useless for testing the viability of the pregnancy if the hCG level is well over 6,000 and/or after 6-7 weeks days of the pregnancy. Pregnancy blood hCG levels are not recommended for testing the viability of the pregnancy when the hCG level is well over 6,000 and/or after 6-7 weeks of the pregnancy. Can hCG levels tell you if your pregnancy is healthy? After 10-12 weeks, the hCG level increase will slow even further and eventually will even decline before reaching a plateau for the duration of the pregnancy.Ī normal hCG rise over several days prior to 6 weeks of the pregnancy usually indicates a viable pregnancy. It makes little sense to follow the hCG values above 6,000 mIU/ml as the increase is normally slower and not related to how well the pregnancy is doing. At an hCG level greater than 10,800 mIU/ml, there should be a visible embryo with a heartbeat.In general, when the hCG level reaches 7200 mIU/ml, a yolk sac should be seen.Above 6,000 mIU/ml, the hCG level often takes over four or more days to double.Between 1,200 and 6,000 mIU/ml serum, the hCG level usually takes 72-96 hours to double.As your pregnancy progresses, the hCG level increase slows down significantly.In early pregnancy, a 48-hour increase of hCG by 35% can still be considered normal.In most normal pregnancies, at hCG levels below 1,200 mIU/ml, the hCG level usually doubles every 48-72 hours and normally increases by at least 60% every two days.What are good hCG levels in early pregnancy? A urine pregnancy test would be expected to be positive around the time of a missed period or 14-15 days after implantation (which can be as early as several days before a missed period).įind out what your levels mean with our hCG calculator! hCG levels are detected in the blood as early as 2-3 days, and in the urine 3-4 days, after implantation. Implantation occurs on average, 9 days after ovulation (with a range of 6-12 days) or about 5 days before a missed period. hCG levels are best checked based on ovulation/fertilization day because the day of the last period can vary.An increase of >=35% in 48 hours can still be considered normal (Seeber 2006 Morse 2012).In a study of 20 patients in the first 40 days of pregnancy, the hCG concentration rose by at least 66 percent every 48 hours in 85 percent of viable IUPs but still, 15 percent of viable pregnancies had a rate of hCG rise less than this threshold.
