The positivity rates of serum hCGβ, intact hCG, and total hCG were 6%
(1/17), 47% (7/15), and 42% (8/19), respectively, with the latter two
having significantly higher positivity rates than hCGβ (p = 0.041). Both
intact and total hCGs showed similar values. The median value of hCGβ,
intact hCG, and total hCG before treatment was 0.1 ng/mL, 4.6 mIU/mL,
and 4.5 mIU/mL, respectively.
