Normal hCG (human chorionic gonadotropin) levels in a non-pregnant girl typically fall within the range of 0.02 to 0.8 IU/L.
Here's a breakdown:
-
Non-pregnant women and girls: The expected hCG level is very low, as hCG is primarily associated with pregnancy. According to the reference, normal levels in premenopausal women range from 0.02 to 0.8 IU/L, and this would also apply to girls.
-
Pregnancy changes everything: It is important to understand that hCG levels drastically increase during pregnancy. These levels usually double every few days in early pregnancy and can range from 20,000 to 200,000 IU/L. But, this only applies if a girl is pregnant.
| Condition | hCG Level (IU/L) |
|---|---|
| Non-pregnant girl | 0.02 - 0.8 |
| Early Pregnancy | Increases rapidly, doubling every few days |
| Pregnancy (around 10 weeks) | 20,000 - 200,000 |
In summary, for a girl who is not pregnant, an hCG level between 0.02 and 0.8 IU/L is considered normal.
