Human chorionic gonadotropin, or hCG, is produced by the placenta during pregnancy. hCG can be detected by a blood test around 3-4 days after fertilization or ovulation, and about 3-4 days after implantation.
The role of a normal hCG count is to maintain the corpus luteum, which is responsible for progesterone production in early pregnancy. Progesterone helps to keep the lining of the uterus thick for a healthy pregnancy.
If there is not enough hCG present in the woman’s body then the lining of the uterus will begin to deteriorate and prevent implantation and pregnancy to continue.
What is the normal hCG count in pregnancy?
There is a wide range in hCG levels in what is considered a normal hCG count in pregnancy. In most normally developing pregnancies hCG levels and the hCG count in pregnancy will double every two to three days early on, then double every 3-4 days.
The beta hCG level count can be monitored several times to see if it is rising appropriately.
Low hCG count in pregnancy
A low hCG count in pregnancy may indicate a miscalculated date of conception, an ectopic pregnancy, or a possible miscarriage. However, a perfectly healthy pregnancy may have low hCG counts and levels.
High hCG count in pregnancy
A high hCG count in pregnancy may indicate a miscalculated date of conception, a molar pregnancy, or a multiple pregnancy
What can interfere with hCG levels and the hCG count?
Some fertility drugs usually hCG injections containing hCG may affect your hCG levels. Other than that, other medications including antibiotics and oral contraceptives will not affect your hCG level. If you are taking a fertility medication that would affect your hCG count then your health care provider should discuss with you how this would affect your tests.
