Hi doctor,

My wife went through sequential IVF 23 days back. I am attaching her hCG reports. Kindly check them. Thank you.



Welcome to icliniq.com. Human chorionic gonadotropin (hCG) is produced during pregnancy. It is a hormone that supports pregnancy by allowing for the production of progesterone. There is sequential rise in hCG (attachment removed to protect patient identity) which suggests pregnancy and it can be confirmed by ultrasonography. Non-pregnant levels are below 5 mIU/mL. Just be careful not to be overstressed, avoid lifting any heavy weights, continue with your medicines and follow-ups regularly.

Hi doctor,

Here we are worried about the hCG level count. Is this a normal growth or ectopic or tubal? Can you please tell us the reason for this slow growth?



Welcome back to icliniq.com. Thank you for your feedback. The hCG levels should increase by at least 53% every two days. There is a wide variation on the normal range of hCG. Since values are still rising so I do not think there is any problem although it is slow which could be due to delayed implantation in some cases or due to ectopic pregnancy. The normal levels of hCG, 3 weeks after your LMP (last menstrual period), is 5 to 50 mIU/mL. Levels peak at about 12 weeks of pregnancy and reach about 300,000 mIU/mL and then peak off. So, as such there is nothing to worry about. A transvaginal ultrasound examination is the best tool right now to confirm this is an ongoing pregnancy and to rule out ectopic or tubal pregnancy to clear the doubt. You can check for heart beat of fetus which usually is seen 23 to 24 days after embryo transfer by transvaginal ultrasound and in 1 month by transabdominal ultrasound.
