HCG levels from normal twin pregnancies

NORMAL TWIN PREGNANCIES

Twin pregnancies tend to show higher HCG levels on a given day of pregnancy. However, there is a large variation in HCG levels between pregnancies, and great overlap exists between single and twin pregnancies.

The values below are from a group of 29 normal twin pregnancies. Because this is a very small group of patients and because lab assays vary, it is important not to rely on these values to determine whether your pregnancy is viable, a single, a twin, etc.

• Check with your physician about your own levels
