Do twins produce more hCG?

Specifically, twin and multiple pregnancies might have 30-50% higher hCG levels than singleton pregnancies. Even so, a detection of high hCG levels can't reliably predict twin pregnancies. That's because hCG levels vary greatly between each woman, and there's a wide range of normal levels.
