Before all, new moms have to highlight that HCG level can be changed following to pregnancy period and normal level HCG is only one of important indicators of healthy pregnancy.
For new mother who want to know if their HCG level is normal or not, they can use home pregnancy test to measure HCG level since this hormone human chorionic gonadotrophin will rise steadily during the early part of pregnancy. If it is less than 5 mlU/ml (milli-International units per milliliter), you are not pregnant according to American Pregnancy Association standard. But if the level is above 25 mlU/ml, congratulations! You are (likely) pregnant. A transvaginal ultrasound can usually detect a gestational sac after the HCG levels have risen to 1,000 to 2,000. By seven to eight weeks after your last menstrual period, levels of HCG should have risen to between 7,650 and 229,000 mlU/ml. Levels of this hormone will usually top off at between 25,700 and 288,000 mlU/ml by nine to 12 weeks since your last menstrual period. By the third trimester HCG levels may have dropped to a range between 3,640 and 117,000 mlU/ml---still well above a reading of 5 or less for a non-pregnant woman. Wow!
